"Babel" by British folk rockers Mumford & Sons won the coveted Album of the Year award at the 55th Grammy Awards on Sunday.

They beat "El Camino" by The Black Keys, "Some Nights" by fun., "Channel Orange" by R&B singer Frank Ocean and "Blunderbuss" by Jack White, at the climax of the music industry's biggest awards show.

The top prize largely came as a surprise after Mumford & Sons lost out in other key categories, although they took the Best Long Form Music Video for "Big Easy Express."

Mumford & Sons had been nominated for Grammys the previous two years, including for Record of the Year in 2012, but had not taken home a prize until Sunday.

Meanwhile, "Somebody That I Used to Know" by Gotye featuring Kimbra won the coveted Record of the Year award at the 55th Grammy Awards on Sunday.

The song beat "Lonely Boy" by The Black Keys, "Stronger (What Doesn't Kill You)" by Kelly Clarkson, "We Are Young" by fun., "Thinkin Bout You" by Frank Ocean and "We Are Never Ever Getting Back Together" by Taylor Swift.

Belgian-Australian Gotye had already won the 2013 best pop duo/group performance and best alternative music album for "Making Mirrors," his third studio album.

He was presented with the best record award by pop icon Prince. "We're pretty huge fans, we've grown up listening to his music ...that's pretty cool," he said, speaking backstage.

"We didn't expect to win... There are so many amazing artists and pieces of music... it's a little bit flabbergasting," he added.

"Somebody That I Used to Know" has been a hit in several countries.
