This full-length sequel, My World 2.0, in stores March 23, won't likely affect any adults not in the direct blast radius of Bieber's target range. That said, the kid seems to know what he's doing.
Those who dismiss Bieber out of hand are missing out on a seriously good pop record, one that mines vintage teen-pop themes but plays like a primer on 2010-model bubblegum.
My World 2.0, his debut full-length album, is far sharper than it needs to be, an amiable collection of age-appropriate panting with intermittent bursts of misplaced precociousness.
It effects a musical anachronism, albeit a catchy one, but in this sped-up recycling moment all styles all at once are grist for the mill.
