Nina Girado

During the nationwide community lockdown amidst the COVID-19 pandemic, Nina staged a two-hour acoustic concert via Facebook Live. The live streaming was held on April 6, 2020 as a treat to her fans and followers, gathering a peak of over 30,000 concurrent viewers. Her live cover of Crash Landing on You soundtrack, "Flower," gained popularity on social media. She later performed the song on variety show ASAP with Morissette.

Nina is a lyric coloratura soprano, possessing approximately four-octave vocal range and the whistle register. She takes good care of her voice, saying "I always order Halo-halo without ice. If I want to eat ice cream, I have to let it melt first or else microwave it. I also don’t eat spicy food or mint candies [...] Of course, it was hard for me [...] But you get used to it." She maintains a healthy food diet to easily recover from throat infections. She sings at least twenty songs a day for practice. In 2011, Nina was featured in a short documentary aired by South Korean network tvN Asia where she was filmed re-attending the Center for Pop Music of the Philippines for vocal training sessions. Apart from her chart-topping original songs, Nina became known for doing cover versions. She described her sound, saying "I can say that the songs I sing in my albums very much represent who I am [...] I try to make it my own even if it was done originally by another artist."

Music critics shared the same opinion on Nina's vocal ability. Baby Gil of The Philippine Star described her voice as "sweet but definitely multi-octave," commenting "This is surely her strongest point and it is really a blessing to know that she can skillfully wield her vocals to conform to the demands of every song." Leonardo Belen from Manila Bulletin complimented her range and technique, saying "Her voice range always amazes people, reaching the highest notes with extreme control and with a sentimental timbre. She renders her songs with emotion and soul, thus made her the Soul Siren." Professional writer-editor Ginnie Faustino-Galgana stated "There is no doubt that Nina is one talented singer. Her vocal range is decidedly wide. Her voice itself has proven itself youthful and adaptable to any beat." Freelance writer Resty Odon said in a review, "Nina can afford to do just covers because she has a voice that’s easy to love." In terms of song selection, he adds "She works the range and volume she sounds best in." She was ranked at No. 6 on the Top 20 Filipina Divas list by the Female Network. She was recognized as one of the Top 10 Singers in the Philippines by the Tinig Awards.

On June 19, 2017, Nina made an appearance on Wish 107.5's Wish Bus roadshow where she performed Charlie Puth's "Attention" and her hit single "Jealous".

Nina had her acting debut for the indie film DAD: Durugin ang Droga, which is an advocacy film promoting awareness on drug addiction. The film was directed by Dinky Doo J.

In February 2015, Nina made a special appearance on the 20th-year anniversary of variety show ASAP where her performance of "Vision of Love" with fellow singers Juris and Kyla became a trending topic in social media. After taking a break from showbiz, Nina publicly announced her secret marriage with husband Coy Enriquez and giving birth to a baby girl, Ysabelle Louise, on December 24, 2015. In an interview with Philippine Entertainment Portal, she expressed her decision to keep her personal life private, stating "I chose to be quiet and just go on with my life normally. I have people in my life who are also into their privacy. [I don't want to drag them in my world] which is totally different to theirs." She added that she is not hooked in social media and she often just post pictures to promote her shows. In 2015, she became part of TV5 reality singing competition Rising Stars Philippines as one of the judges. On June 14, 2016, she was featured on the debut single of R&B duo Joshua Desiderio and Lloyd Zaragoza (JO.LLO), entitled "Ikaw ang Bida."

Nina began dating fellow acoustic singer and PAGCOR official Jimmy Bondoc in 2002. During their relationship, the couple acquired real estate properties in Boracay which were later sold after their break-up in 2005. Reportedly, Nina's family was not in favor of their relationship. In November 2005, she began dating fellow musician Nyoy Volante who was also her close friend at the time. They became close while working on the El Niño, La Niña (2004) concert and her self-titled studio album. The couple broke up in May 2007 due to unresolved financial conflict. A year later, Nina began dating businessman Enrico "Coy" Enriquez. The two met through Dard Enriquez, Coy's brother, who became Nina's band guitarist. In November 2009, Nina announced her engagement with Enriquez. In 2015, they were secretly married after an eight-year relationship and she gave birth to a baby girl, Ysabelle Louise, on December 24, 2015 via painful normal delivery. She labored for 13 hours and decided to give birth without anaesthesia to feel the sacrifices of being a mother.

On January 25, 2013, Nina staged her comeback concert at the Music Museum entitled Nina Reborn, accompanied by the release of her first album under Viva Records entitled All Good. The concert had its cable television premiere on May 4, 2013 at 9:30P.M. PST on Filipino cable channel PBO (Pinoy Box Office). Manila Bulletin gave Nina Reborn positive response, saying "Nina as a powerhouse singer is a given, but the seeming restraint she demonstrated that night was just as effective and lent her vocals more heft and soul." The Philippine Star stated, "Nina is one of those interpreters who can take on any song [...] The results are very good." All Good consists mostly of original songs, with five cover versions of OPM classics. The album was a critical acclaim, with The Philippine Star explaining that its purpose is "not to surpass her previous achievements, but to empower its belief that [Nina] has more to offer as a recording artist." Journal praised the album's sound, stating "A more mature Nina is what people will hear [...] All Good is a suite of beautiful songs." "Sa Isang Tingin" was released on February 23, 2013 as lead single for the album. It was described to having a "strong melody [that is] somewhat influenced by high-recall Tagalog songs of the yesteryears." Despite being claimed as an official single, no music video was recorded for the song's promotion. On March 3, "Hurting Inside" was released as a promotional single, accompanied by a lyric video published on Viva Records' official YouTube page. On October 22, "When the Love Is Gone" was used as theme song for the 2013 romantic drama film of the same title.

Several Asian pop artists have covered Nina's original songs. In 2009, South Korean boy band Super Junior recorded "What If" (2003) for their album Sorry, Sorry. In 2010, Japanese singer Yoshika covered "Someday" (2006) for her album Redwood Tree. On January 1, 2013, Jessica Jung of Girls' Generation and Krystal Jung of f(x) performed the same song in the TV special Girls' Generation's Romantic Fantasy.

On May 8, 2012, Nina signed a five-year recording deal with Viva Records, following the expiration of her contract with Universal. In an interview, she stated that during her Love2Love2Love concert in 2010—which was produced by Viva Entertainment, the label's head Vicente Del Rosario, Jr. expressed interest in managing her career. However, she has already signed under Universal at the time. Shortly after her separation with the label, she transferred to Viva with the help of Geleen Eugenio. She expressed working on a new album, saying that it will have "the same Nina sound [...] New songs maybe, can be cover, can be original, but we’re eyeing on original songs." She also planned to do acting workshop in Singapore, stating "I myself, honestly, don't know much about acting. So if ever I will star in a movie, I'm not half-baked, I'll be prepared. And also for myself, I want to be prepared, especially if I'm heading straight into a new direction." Nina posed on the Burlesque-inspired cover of Playboy Philippines magazine's May—June 2012 special issue where she is seen nude, only her private body parts being covered. She stated that it was personally her decision to do a daring shoot, and later explained that it is her way of "immortalizing herself in her best shape yet." She also mentioned working on a big theatrical play as preparation for her acting debut. In October 2012, she appeared in a cameo role for the film A Secret Affair, where she performed the movie theme song "Don't Say Goodbye". In the last quarter of 2012, she was given a weekly segment on TV5 variety show Wil Time Bigtime entitled "InstaJam," and was promoted to regular performer in 2013 for the segment entitled "Mini Concierto" under the show's new title Wowowillie.

On February 5, 2011, she staged a pre-Valentine concert with the Sessionistas at the Araneta Coliseum entitled ASAP Sessionistas 20.11. Her performances of "Note to God" and "Got to Be There" were applauded by fans and critics alike. Following this, she was cast as Megara and Deianira on Hercules 12, a pop-emo musicale, but later dropped out due to conflicts with her schedule. On March 18, 2011, she was invited as Philippine representative to perform at the Pattaya International Music Festival 2011 Galaxy Stage in Thailand where she was presented the "Golden Key to the City of Pattaya" by the city mayor. Among other Asian performers she joined are Derrick Hoh, Golf & Mike, Chin Chinawut and Ice Saranyu On March 25, 2011, she was featured in a short documentary, along with Gary Valenciano, which was aired on South Korean network tvN Asia. In June 2011, issues of maltreatment to her former personal assistant surfaced the news.

In August 2011, she joined the ASAP Sessionistas' second U.S. tour which ended in September. In December 2011, she became part of concerts by Noel Cabangon and Duncan Ramos. In the same year, she was featured on the albums of Kris Aquino and Cabangon.

Late in 2010, Nina revealed that she was recording a studio album set for release in mid-January 2011. It was originally set to be the first of her two-album recording deal with her new label, Universal Records. After a couple of push-backs, Stay Alive was finally released on November 19, 2011. In choosing such title for the album, she explained, "It's like some people are saying that I'm gone [...] So I’m here to say that I’m still here and staying alive." She called the album "special" due to the fact that she contributed from its musical production to the cover art design." Stay Alive was a universal acclaim, being called "futuristic and edgy" by critics who also predicted that it "may set new trends in Filipino music," tagging Nina as the new "dance diva." Philippine Entertainment Portal praised the album, stating "Stay Alive is a testament to Nina's evolution as an artist and determination to be a better performer." "Dance" was released on October 6, 2011 as the lead single from the album. Nina explained, "The carrier single is a dance song for it to be different from my previous albums." The song is described as "an upbeat track with a catchy melody." Its music video was released on December 9, and features Nina in Gaga-ish costumes while performing a dance routine. Due to lack of promotion, the song failed to achieve commercial success. On January 30, 2012, "However Much Love" was released as a pre-Valentine promotional single. The song was critically acclaimed, being called a "standout" by Abby Mendoza of Philippine Entertainment Portal. It was a commercial success as well, becoming Nina's first chart-topper since 2008. On February 13, she staged a pre-Valentine concert entitled Update Your Status... at the Music Museum which supported the album. In the same month, she expressed disappointment with the album's lack of promotion, saying "[Universal] always have a meeting, but no actions are initiated. They give us schedules that are not really followed. When it's already okay, then they cancel it." On April 14, she staged another concert at the Music Museum, entitled Timeless: Tribute to a Diva, which was dedicated to late pop diva Whitney Houston. "Believe in the Dream" was released on April 24, 2012 as the third single from Stay Alive, accompanied by a lyric video.

In November 2009, Nina was one of forty Filipino artists who contributed to "Kaya Natin Ito", benefiting the victims of Typhoon Ondoy. She was vocally coached by Regine Velasquez and was asked to do an impromptu whistle as her solo part on the song. All proceeds from the sale of the song went towards the disaster relief efforts of the Philippine Red Cross and Gawad Kalinga. On June 30, 2010, she was one of the Universal Records artists who performed the song "Bagong Pilipinas", composed by Ogie Alcasid, for the inauguration of Philippine President Noynoy Aquino.

Later, she performed on Aquino's victory street party with Kyla, Jay R and Jed Madela. On October 22, 2010, she had a concert at The Terraces, Ayala Center Cebu entitled Think Pink.

In January 2009, ASAP, a musical variety show on ABS-CBN where Nina has been a regular performer since 2003, paired her with other artists who are also in-demand performers in various bars and restaurants. Among them are Duncan Ramos, Aiza Seguerra, MYMP, Sitti and Richard Poon, forming a group called the "Sessionistas." The Sessionistas became the most-requested jamming segment on the show, leading the ABS-CBN management to stage the ASAP Sessionistas Live concert at the Araneta Coliseum. The concert at the big dome was sold-out, and it was followed with other sold-out concerts in Cebu City, Batangas City and in their U.S. tour. On May 8, 2009, Nina was invited as special guest on STAR World's variety talk show, Asia Uncut, making her the second and last Filipino to appear in the show, next to Lea Salonga. During her interview, she was officially declared as the "Asia's Soul Siren." In 2009, Nina publicly announced that she would file an estafa (fraud) case against ex-boyfriend Nyoy Volante's parents, Evangeline and Oliver, due to failure in fully settling their debts amounting to ₱1.4 million in total. She decided to finally take legal action after the couple broke the compromise agreement between the two parties.

In September 2009, Nina released her fifth studio album, Renditions of the Soul, another cover album which came from her special weekly acoustic radio show of the same title which aired on Wave 89.1 during Friday and Sunday evenings. The album gave her record-producing debut when she produced all the album's tracks herself. It was well received by critics, with Manila Bulletin stating "The 17-track album is more emotionally subtle, yet the songs just have as equally powerful messages like her previous hits [...] Nina’s singing perfectly renders the message of every selection: Love, longing and the purity of emotional surrender." "I'm Yours" was released in May 2010 as the only commercial single from the album. Warner held a sing-along contest for Nina fans and the winner got the chance to be on the single's music video. However, the single had no promotion, since Nina has left the label during its release. The video barely features her, and just shows some of her photos from the Renditions of the Soul album photo shoot. The album was commercially successful, being able to reach Platinum status in July 2010 despite having the least promotion.

In 2008, Nina released another cover album, where Warner collaborated with Diane Warren for the second time. It is entitled Nina Sings the Hits of Diane Warren, and consists of successful ballad hits written by Warren. The album was certified Gold by the PARI after one week of commercial release, and eventually, it turned Platinum. Its official singles include the Aerosmith original, "I Don't Want to Miss a Thing", and the Faith Hill original, "There You'll Be", which Nina describes as a "thank you" to her fans. She expressed her gratitude in an interview, saying "I still have much to fulfill [...] I owe it to my fans [...] showering me with love and unbridled affection." The album was panned by critics, with Titik Pilipino stating "To be honest, what [they]'ve been expecting at this point in Nina's career is an album of original compositions suited to her voice [...] she didn't have to shout and be a vocal Chinese acrobat." OPM critics reacted negatively to the kind of musical process she was doing, noticing that her most popular albums, Nina Live! and Nina Featuring the Hits of Barry Manilow, contain covers. Her most popular singles, "Love Moves in Mysterious Ways", "Foolish Heart" and "Through the Fire", are also revivals. In an interview with the entertainment press at Red Box, Nina defended herself, saying "It's fulfilling to sing any song, maybe a cover or an original song, just the fact that I'm singing is fulfilling enough." She further stated that her fans were the ones who requested it. In the same year, she was featured on the self-titled debut album of Gabby Concepcion.

In 2004, Nina was honored as the Singing Ambassador of Goodwill by the Center for Pop Music Philippines for performing for the less-fortunate institutions, fund-raising concerts and inspirational talks to students. She also became part of the recording for the song "Biyahe Tayo", which was used to promote Philippine Tourism (WOW Philippines), mentioning the different provinces, scenic spots, and events of the country.

In an interview with SNN: Showbiz News Ngayon's Kris Aquino which aired in February 2009, Nina stated that she would file an estafa (fraud) case against Volante's parents, Evangeline and Oliver, for failing to settle their debts. She explained that in 2007, the couple borrowed ₱1.4 million from her. The following year, Oliver issued several checks as payment. However, some of the checks bounced. In July 2008, she entered into a compromise agreement with the couple under which Evangeline immediately paid her ₱300,000 in cash. The couple also agreed to settle the balance of ₱1.1 million in monthly installments—from August 20, 2008 to February 20, 2010. They issued her nineteen post-dated checks which were signed by Oliver. She said that she was able to encash some of the checks. However, the rest of the checks—which totaled ₱550,000—were not honored due to insufficient funds.

In August 2007, Nina was chosen by Sean Lim, director of sci-fi indie film Xenoa, to record the theme song, "Collide", for the movie. The song was nominated for Best Song Written for Movie/TV/Stage Play on the 2008 Awit Awards. In October 2007, she re-released her self-titled album in a special limited edition entitled Nina Featuring the Hits of Barry Manilow. The album consists of two discs—the standard edition and a 9-track compilation which features her renditions of Barry Manilow originals. It is also considered to be a product of her Very Manilow concert at the Music Museum. "Somewhere Down the Road" and "If I Should Love Again" were released as commercial singles, and both peaked at number two on local charts. A few days after the release of Nina Featuring the Hits of Barry Manilow, Warner and Club Myx (the label) released her first remix album in collaboration with DJ Dense Modesto, entitled Nina in the Mix: The Dense Modesto Remixes. Also in 2007, she became part of Thor's cover album Soul Obsessions... Duets with Thor, singing a Mariah Carey original, "Whenever You Call". In 2008, Nina Featuring the Hits of Barry Manilow earned a Platinum certification by the PARI, making Nina (the album) double platinum.

In November 2007, Nina won the Monthly Champion title on ABC-5's Shall We Dance? where she competed against bossa nova singer Sitti and actress-comedian Tuesday Vargas. She and her partner, Efren Ibo, performed a freestyle-jive inspired by Beyoncé's song "Irreplaceable". Judge Audie Gemora was impressed with her performance, commenting that she both sings and dances cleanly. World Ballroom Champion and judge, Ednah Ledesma, congratulated Ibo for bringing out the best in Nina. Another judge, Regine Tolentino, reacted positively, saying she and Ibo took their dance to another level. The episode aired on December 2, 2007. On January 18, 2009, Nina competed against Iya Villania and Sitti on ABS-CBN's Magpasikat, a temporary replacement for the suspension of the noontime TV show, Showtime. She received positive comments and opinions from the judges, which led her to be the winner, sharing the title with Sitti. Later during the show, it was announced that Showtime would be back on its regular time slot after a court granted a Temporary restraining order (TRO) from the Court of Appeals against the 20-day preventive suspension by the Movie and Television Review and Classification Board (MTRCB). In May 2011, she joined The G-Force Project dance recital, performing a burlesque dance.

In 2006, she released her self-titled album which earned her the most nominations (eight) for the Awit Awards. Later, she was criticized for releasing too many covers, and got in a feud with her ex-boyfriend Nyoy Volante's parents when she filed a lawsuit against them. She regained success in 2009 after performing and touring with the Sessionistas. In the same year, she released her last studio album under Warner, Renditions of the Soul, which was taken from her Wave 89.1 radio show of the same title. The album was both critically and commercially successful. She signed a recording deal with Universal Records in 2010, and represented her country in the Pattaya International Music Festival a year later.

Nina released her self-titled fourth album in August 2006. She decided to release a self-titled album due to the fact that she has already established her name as an artist, and would like the public to know her as who she really is. She also admitted that Nyoy Volante was an inspiration for the album, saying "[Volante's compositions] were just so beautiful and inspiring that eventually I was encouraged to create an all-original album." Titik Pilipino praised her in a review, saying "Nina does almost everything right [...] She’s more refined, polished." On the November–December 2006 issue of MYX Mag, Mike Luis of Freestyle reacted positively to the album, stating "The mid-tempo tracks are groove-worthy, the slow jams are sexy, and the two remakes were nicely done." "I Do", a song that is heavily influenced by R&B-dance, was released as the album's lead single, but it was the second single, "Someday", that topped the local charts, staying in the position for eight weeks. "Someday" also received positive response from music critics. The Philippine Daily Inquirer described the song as "introspective, traffic-stopping [...] that boasts of a rich melody and Nina’s emotive panache." In 2007, she released the third and final commercial single, "I Can't Make You Love Me", which was both critically and commercially successful. The song topped the radio charts and became a critical acclaim, with the Philippine Daily Inquirer stating "Bonnie Raitt’s anthemic song for the lovelorn is hard to top, but Nina gives a beautifully dressed-down version."

In June 2006, Nina became the spokesperson for Goldilocks Bakeshop, and released her "considered-to-be" first ever physical single, "Araw Mo", a birthday song used for the promotion of Goldilocks' 40th anniversary of service. Sales of the single entirely went to charity, the Leukemic Indigents Fund and UNICEF. Aside from Goldilocks, she has done a commercial for Ellips Cologne, with fellow acoustic singers Nyoy Volante, Luke Mejares, and Jimmy Bondoc–each rendering an excerpt from songs identified to them like “You're My You” (Volante), “Let Me Be the One” (Bondoc) and “Because of You” (Mejares) on the commercial. Her songs were also used for Colgate and Nescafé commercials. She was even chosen to be the first Filipina to endorse Sennheiser microphones. She also became a testimony for Gan Advanced Osseointegration Center (GAOC). Mango, Levi's and Mark Alexander became her sponsors. In 2007, Nina strutted onstage during "The Lion King" segment of Furry Tales fashion show, after not being included on the "Penshoppe Denim" segment. She has become part of musical variety show ASAP on ABS-CBN, variety game show Wil Time Bigtime on TV5, and has hosted her own weekly radio show on Wave 89.1 entitled Renditions of the Soul.

In 2005, Nina temporarily broke away from the urban-influenced sound to record covers of classic love songs. She came out with her first live album, Nina Live!. The album is composed of classic love songs from the 1970s to the 1990s, which she recorded live at the PHI Resto and Bar in Metro Manila on January 30, 2005. According to her, the idea of a live album started when Warner saw her performing on different bars and lounges. The label told her, "Why not put it in CD form or in a DVD, so that the people could take home [her] show." The first single, "Love Moves in Mysterious Ways", was released in February 2005 along with the album. It peaked at number one on local charts for twelve consecutive weeks, becoming Nina's biggest hit to date. Before the second single was released, Nina Live! was already certified 3× Platinum by the Philippine Association of the Record Industry (PARI), eventually selling 90,000 units in the Philippines. "Through the Fire" is the second official single which also peaked at number one for a week. The song features her highest recorded vocal register in full chest voice to date. "Constantly" was released as the third official single and was immediately followed by the final commercial single, "I Love You Goodbye". Nina Live! sold over 300,000 copies in the Philippines in 2009, certifying 10× Platinum (Diamond) by the PARI and becoming the fourth best-selling album in the Philippines. Is is also the best-selling live album and best-selling album of the 2000s. The album allowed Nina to become the first female artist in the Philippines to receive a Diamond certification. Overall, she is the third artist next to Jose Mari Chan and Eraserheads. Aside from outstanding commercial performance, Nina Live! was well received by OPM critics. In a review, Titik Pilipino stated "this album only proves that Nina can do wonderfully with covers."

Nina Live! was later released in home video, and was followed by a concert at the Araneta Coliseum. In 2005, Nina was listed at No. 75 on Philippines' FHM 100 Sexiest Women in the World. In the same year, she collaborated with American singer Joe Pizzulo in his album, All the Best. In 2006, she dated long-time friend and fellow acoustic singer Nyoy Volante, but the two broke up a year later. In February 2006, she was chosen to sing the theme song for I Will Always Love You, which eventually became the highest-grossing movie of GMA Films. In June of the same year, Goldilocks Bakeshop chose her as spokesperson for their 40th anniversary (40 Thoughtful Years), where she recorded the promotional song "Araw Mo". In the same year, she appeared on Hotsilog: The ASAP Hotdog Compilation, covering Hotdog's seductive ballad "Lumapit Ka".

Sarah Geronimo has cited Nina as one of her influences. She expressed wanting to sing with Nina for her 2005 concert The Other Side at the Araneta Coliseum. Morissette Amon has stated that Nina's rendition of "Foolish Heart" (2002) inspired her on the use of whistle register. She also credits Nina's toned-down vocal style as it influenced her to be "steady" [sic] in terms of singing. She paid tribute to Nina in one of her recorded live performances. X Factor contestant and singer Katrina Velarde also performed a medley of Nina's popular songs in one of her concerts. Regine Velasquez has cited Nina as one of her favorite artists and has performed Nina's original songs in her live shows.

In a career spanning over a decade, Nina was cited as the artist who popularized the acoustic phenomenon in the Philippines. In 2004, the Philippine Business Excellence Award named her as the No. 1 Female R&B Singer in the country. In addition, MEGA listed her as One of the Women to Watch in 2004. In 2009, Nina Live! was certified Diamond by the PARI, becoming the fourth biggest-selling album in OPM history. It holds the record for best-selling live album and best-selling Filipino album of the 2000s, also making Nina the first female Diamond recipient in the Philippine music scene. She was named as the best-selling female recording artist of 2009 by the Guillermo Mendoza Memorial Scholarship Foundation. In 2011, Wave 89.1 Urban Music Awards presented her a Special Achievement Award for her contributions to the music industry. Aside from her commercial success, she has earned ten Awit Awards.

In early 2004, Nina became part of the recording for the song "Biyahe Tayo" which was used for the WOW Philippines...Biyahe Tayo! campaign. The campaign was founded for the promotion of Philippine Tourism. Artists who participated in the campaign included Lea Salonga, Sharon Cuneta, Francis Magalona and other famous Filipino acts. In November of the same year, she was chosen by popular American songwriter Diane Warren to record the Cyndi Lauper original "I Don't Want to Be Your Friend", which became a chart-topping hit in the country, for Warren's love songs compilation album Diane Warren Presents Love Songs. She is the only Asian artist featured on the album. In the same month, Warner Music Philippines released a Christmas album which features her and some of the label's in-demand acts at the time, including Christian Bautista, Kitchie Nadal, Dice & K9, Paolo Santos, Thor and Artstrong. The album was followed by their first major concert as a group, held at the Folk Arts Theater, entitled Pop Ko 'To! The All-Star, All-Hits Concert. In the same year, she appeared on the debut albums of Bautista and her brother, King.

Apart from singing, Nina plays musical instruments such as piano and acoustic guitar. She credits her older brothers for her interest in playing instruments. Her first live television appearance playing the piano was during the Pop Ko 'To! The All-Star, All-Hits Concert (2004) where she performed "I Don't Want to Be Your Friend." She believes playing the piano is the key to becoming a songwriter and composer.

In December 2003, Nina released her second studio album, Smile, accompanied by its lead single, "Make You Mine". The album's sound is bigger and bolder than her debut album's, consisting of upbeat rhythmic jams and powerful sentimental ballads. "Make You Mine" was described as a "rich harmonic chemistry of Nina's mesmerizing vocals and hypnotic urban-style beats with a blend of funky strings, an upbeat R&B piece that offers a blissful listening experience." It became her third number one single, making Nina the first female OPM artist to have three number one singles in a span of one year. The following single, "A Girl Can Dream", features her labelmate Christian Bautista in the music video. The song peaked inside the top five of charts. "Sayang Naman" is the first Tagalog single that she released and it became the last commercial single from the album. It reached the top ten of local charts, but is considered to be her least successful single at the time. Smile gave Nina her songwriting debut when she wrote the song "Can't Say I Love You" in it. The song was described as a "sensually engaging ballad."

In the last quarter of 2002, Nina released her debut album under Warner Music, entitled Heaven, alongside her first single of the same title. The album is inspired by contemporary R&B and pop music, and it was well received by critics, with The Philippine Star stating "Heaven is quite a package. Production is sleek and Nina’s delivery, smooth [...] it is never heavy nor frenetic. It is instead used as a stable base for Nina’s sweet but definitely multi-octave singing voice." The lead single, "Heaven", did not really become a commercial hit despite peaking inside the top ten of Philippine charts. In December 2002, "2nd Floor" was released as a radio-only single. Even though the song was not commercially released, it charted inside the top ten and won her the Best R&B Song award on the 16th Annual Awit Awards in 2003. "Jealous" was released as the second official single and it became Nina's first number one hit, topping various Philippine charts for three weeks. It also allowed her to grab the Best New Artist award on both Awit Awards and MTV Pilipinas Music Awards in 2003. The third commercial single is her acoustic version of Steve Perry's "Foolish Heart", which became her second number one single as it charted even better than her previous releases. The song was a critical acclaim, being described by critics as "proof of Nina's musicality." "Loving You", a Ric Segreto original, became the last commercial single from Heaven. It did not top the local charts, but peaked inside the top five. In October 2003, the album was re-released when it reached the double platinum mark.

Nina has cited Mariah Carey as major influence in her singing career, notably in her debut album Heaven (2002). She is known to have a similar vocal range, musical style and prominent use of the whistle register. She has performed Carey's songs both in her arena concerts and small venue live shows. Early in her career, Nina admitted that she never attempted to watch concerts before she became a recording artist until Carey's Charmbracelet Tour in Manila. In an interview, she stressed the originality of her sound, saying "It's not like I want my career to imitate or even be compared with [Carey]'s. In the end, I want to be acknowledged as a singer of my own brand of music." Aside from Carey, she has cited Whitney Houston, Alicia Keys, Gary Valenciano, Ella Mae Saison and Regine Velasquez as influences. She has collaborated with international acts including Diane Warren, Joe Pizzulo, The Cascades, Fra Lippo Lippi, Keith Martin, Kenji Williams, David Pomeranz, Lea Salonga, Billy Crawford, Charice Pempengco and Arnel Pineda of Journey.

Nina has recorded music videos with dance steps and professional choreography, including her singles "Heaven" (2002), "Make You Mine" (2003), "I Do" (2006) and "Dance" (2011). She has also incorporated dancing in her song numbers during live concerts and stage performances, notably in Nina Just Wanna Have Fun (2005), Nina... The Diamond Soul Siren (2010), Update Your Status... (2012) and Nina Reborn (2013). During her shows, she has performed the songs "Get Right," "It's Like That," "Radar," "Hot n Cold," "Wings" and "Price Tag" with choreography. "Staying Alive," "Only with You" and "I Came to Dance" (2011) are original songs that she performs live with synchronized dance routine and back-up dancers. Nina's choreography consists of various genres, including pop and ballroom dance. She had a recurring appearance on ASAP's pop/hip-hop dance segment "Supahdance Plus." When she was a kid, Nina took up ballet classes but soon stopped to focus on singing. In 2010, she pursued ballet along with playing tennis to keep herself physically fit. In 2020, she flew to South Korea to undergo K-pop dance workshop.

In 2000, she finished Accountancy while performing for different bands including The Big Thing, MYMP, Silk and the Essence. After college, she recorded an amateur demo CD with the help of a friend. It was composed of three tracks including her rendition of Steve Perry's "Foolish Heart", "Breathe Again" and "Against All Odds (Take a Look at Me Now)." The demo was recorded in a home studio with only a guitar for accompaniment. Her brother King brought her demo to different recording labels. Ricky Ilacad, who was managing director of Warner Music Philippines at the time, listened to the recordings and immediately planned to sign her up even without seeing or hearing her in person. Two months after her father died of a heart attack in the U.S., Nina signed her first recording contract with Warner.

Nina's musical style and voice have set some remarkable trends in OPM and acoustic music. According to The Philippine Star, "Nina deserves to be called as one of local music's treasures. Her album titled Nina Live! became a benchmark in acoustic recording." The album's format has influenced and has been adapted on the live recordings of artists such as Freestyle, MYMP, Sitti, Christian Bautista, Rachelle Ann Go and Aiza Seguerra. Music critic Remy Umerez of Journal wrote, "Nina set the bar high for female singers of her generation with the multi-platinum success of her solo albums in the mid-2000s." In a review for All Good (2013), Yugel Losorata of The Philippine Star opined that the album "reflects [Nina]'s mindset of thanking back the local music scene that has provided her blessings other lady acts can only dream of."
