My World is the debut extended play (EP) by Canadian recording artist Justin Bieber. It was released on 17 November 2009, by Island Records. The album is considered the first half of a two-piece project, later being supplemented by his debut studio album My World 2.0 (2010). After signing a recording contract in light of his growing popularity on YouTube, Bieber worked with collaborators including his mentor Usher, in addition to producers Tricky Stewart, The-Dream, and Midi Mafia. Its music incorporates pop and R&B styles, and lyrically discusses teen romance and coming of age situations.
