The biggest debut of 2012 doesn’t belong to a glossy pop act like One Direction or Justin Bieber.
Sure, those boys have hordes of teenage girls ready to download their music at the drop of a tweet, but they’ve got nothing on the scruffy gents of Mumford & Sons, whose new disc, Babel sold 600,000 copies in its first seven days. (The next-best opening? Bieber’s Believe, with 374,000 in week 1.)
