Mumford and Sons sold 600k of their new CD ‘Babel’ in the first week which marks the biggest selling debut of the year. Babel‘s amazing sales far outshine the next-best debut of the year, Justin Bieber’s Believe, which sold 374,000 copies in its first week.

“Of the 600,000 copies that Babel sold, a whopping 420,000 (72 percent) of them were digital albums. That’s the second-biggest digital sales week ever behind Lady Gaga’s Born This Way, which sold 662,000 digital copies thanks, in part, to its controversial 99-cent deal on Amazon.”

The Music business is exceptional with absolutely no formula or guidelines. One week it’s a Korean gangsta rapper, the next week it’s a couple of white guys with banjos.
