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