Justin Bieber's chart record to land the biggest first-week sales in the US so far this year.
Bieber's Believe album originally sold 374,000 copies in its first week, with the UK folk band's second LP Babel smashing the 18-year old's achievement by shifting 600,000 units to score their first No.1 on the Billboard 200 countdown.
According to Billboard, Mumford & Sons first-week sales also eclipse Madonna's MDNA which sold 359k copies in its first week, while Pink's The Truth About Love managed to sell 280k - leaving her in fourth place.
Babel has also claimed the second biggest first-week digital sales ever after it was downloaded 420,000 times, with only Lady GaGa's Born This Way album selling more.
GaGa's sophomore LP still remains the biggest digital album ever in terms of sales over its first seven days after selling 662,000 downloads when it went on sale in May 2011.
