This song was also used for television ads for Boohoo.com, Deezer and America's Next Top Model. The song was widely supported on BBC Radio 1 and other UK national radio stations.

Mason is the stage name of Dutch music DJ & producer Iason Chronis (born 17 January 1980). He had a number one on the UK Dance Chart in 2007 with his track "Exceeder". Exceeder had originally been an instrumental and had received a vinyl-only release in the UK in 2006. The new version of the track, "Perfect (Exceeder)", was a mashup with American rapper Princess Superstar's song "Perfect" and reached number 3 on the national British chart in January 2007. The track was a big hit in many countries worldwide. He also had chart success in 2011 with his song "Runaway", which was a modern version of "Runaway" by Eruption, and "Boadicea", featuring Róisín Murphy, in 2016 with "Fashion Killa" (feat Stefflon Don), and with many club releases since. Mason is the owner of the record label Animal Language.

In 1995, he started doing DJ performances, initially in and around Amsterdam but later abroad. In 1999, he took a four-year course in Music Composition and Performance, which he graduated with honours and for which he received an award from the Dutch Royal Family. He used his violin skills during his DJ sets between 1999 and 2005. During his world tour with Tiësto in 2004, he played the violin during a live performance of "Lethal Industry", as well as being Tiesto's warm up DJ.
