My World 2.0 is the debut studio album by Canadian singer Justin Bieber, released on March 19, 2010, by Island Records. It is considered the second half of a two-piece project, being supplemented by his debut extended play  My World (EP) (2009). 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. The record follows in the vein of My World, incorporating pop and R&B styles, and also experiments with hip hop elements. Lyrically, it discusses teen romance and coming of age situations.
