YouTube sensation Justin Bieber's debut album piles on the production values and features songs written by Justin Timberlake and Usher, as well as a Cardigans cover (the standout song "Love Me"). While he infuses his lines with plenty of emotion, he relies heavily on electronic gimmickry to guide his still-maturing vocals. Regardless, the danceability of these tunes can't be denied, and if you're looking for pop hooks and perfect ringtones, My World could not work harder for your affection.
