Hello guys, I think I've gone for ages. haha :)

Carl Falk is a songwriter. He wrote 'What Makes You Beautiful', 'Live While We're You', 'Kiss You', and so on (you can see it on the tracklist) for One Direction. He also wrote 'Starships' and 'Pound The Alarm' for Nicki Minaj. He wrote many songs for famous artists such as One Direction, Demi Lovato, Westlife, Akon, Taio Cruz, Nicole Scherzinger, Labyrinth, Nicki Minaj and so on
