Justin Bieber - My World (2009)

This is R&B-tinged pop from a superstar in the making. After being plucked from YouTube and paired up with R&B megastar Usher, Justin Bieber made his pop debut with My World, a mini-album that shows off his supple voice, optimism-charged outlook, and—most crucially—his sweetly romantic charm. The percolating synths of “One Time” and gently strummed guitars of “One Less Lonely Girl” highlight the crush-inducing appeal of his still-unchanged voice, while Usher’s cameo on the slow jam “First Dance” doubles as a torch being passed by a fellow pop prodigy.
