In 2015, Littooij released two extended plays called Met de tijd mee, deel 1 en Met de tijd mee, deel 2. Included on the EPs is the single "Sexy als ik dans", among others.

His song "Beauty & de brains" was released as single and was certified Platinum by the NVPI. Littooij started working on his first studio album, Zo van ah yeah. It was released in March 2014 through Pacemaker Music. Several singles preceded the album, including "Hoe", a Platinum-certified collaboration with Miss Montreal and "Mannenharten", a collaboration with BLØF (the title song of the movie of the same name). The album reached the second position on the Album Top 100.

With the 2014 single "Sexy als ik dans", Littooij achieved his first success in Belgium. It reached the peak position in the Ultratop 50 and was certified Platinum by the Belgian Entertainment Association. The single also performed well in his own country, where it became his third Platinum-certified single. When King Willem-Alexander visited Littooij's home city of Dordrecht on Koningsdag 2015, Littooij was chosen to end the festivities with a performance of "Sexy als ik dans".

During his education at the Herman Brood Academy, Littooij developed a passion for songwriting, especially for writing Dutch songs. Littooij participated in the 2012 talent show De beste singer-songwriter van Nederland (English: "The best singer-songwriter of the Netherlands"), broadcast by VARA, BNN and 3FM. This was a great opportunity to reach a broader, national, audience for his self-written songs. In the first episode, Littooij performed his song "Beauty & de brains", which became an instant hit. Although Littooij lost the competition in favor of Douwe Bob, he had achieved national fame and popularity.

In 2009, Nickelodeon asked Littooij to be part of a new-formed dance and music trio called Zirkus Zirkus. With Zirkus Zirkus, he released several singles and one studio album called In de tent. The trio was aimed at children and they appeared on TV in several Nickelodeon programmes. The trio had some moderate success: three singles charted on the Single Top 100. In 2011, they split up.
