Mumford & Sons have a big debut on Billboard 200. Their second album "Babel" easily tops the chart as it sells 600,000 copies in its first week, according to Nielsen SoundScan. The number marks the biggest debut this year, surpassing Justin Bieber's "Believe" which sold 374,000 copies in its first week.

420,000 of the albums sold were from digital downloads. It's the second-biggest digital sales week ever, placing behind Lady GaGa's "Born This Way" which sold 662,000 downloads in 2011.

In terms of overall sales weeks in 2012, the Marcus Mumford-fronted band's follow-up to "Sigh No More" is put one place behind Adele's "21". The "Someone Like You" hitmaker's sophomore set sold 730,000 copies in its 52nd week, thanks to the boost it received from the Grammys.

Two other rock bands, Green Day and No Doubt, enter the chart at the second and third place respectively. "Uno!" by Billie Joe Armstrong and co. sells 139,000 copies, while the Anaheim-originated group's "Push and Shove" moves 115,000 copies.

The entrance of three new releases pushes Pink's "The Truth About Love" to the fourth place after staying atop the chart last week. It sells another 94,000 copies, down 66|percent|. Following it at No. 5 and 6 respectively are other new entries, Lupe Fiasco's "Food and Liquor 2: The Great American Rap Album Pt. 1" (89,000) and Deadmau5's "Album Title Goes Here" (58,000).

The rest of the spots in the top 10 belong to holdovers. The G.O.O.D. Music "Cruel Summer" compilation presented by Kanye West falls from No. 2 to 7 with 55,000, Dave Matthews Band's "Away From the World" slips 4-8 with 36,000, Little Big Town's "Tornado" drops from No. 5 to No. 9 with 34,000, and The Killers' "Battle Born" steps down from No. 3 to 10 with 31,000.
