Limited vinyl LP pressing of this 2009 release by the Canadian pop sensation. My World is the debut extended play (EP) by Justin Bieber. 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. It's music incorporates pop and R&B styles, and lyrically discusses teen romance and coming of age situations. Two singles were released from My World, both of which became international successes. It's lead single "One Time" reached the Top 20 in five countries' singles charts, while it's follow-up "One Less Lonely Girl" peaked within the Top Ten in Canada and Top 15 in the United States.
