Gotye's 'Somebody That I Used to Know' was the biggest selling song of 2012 in the US.

The Belgian-Australian singer's track sold 6.8 million copies, beating Carly Rae Jepsen's 'Call Me Maybe', which was second, with 6.4 million sales.

'Somebody That I Used to Know (Featuring Kimbra)' became a phenomena in 2012, catapulting the previously unknown artist to the spotlight. The song has sold over 10 million copies worldwide and reached number one in more than 23 national charts, becoming the fourth most downloaded track of all time.

Speaking of the track, Gotye - real name Wouter De Backer - said he doesn't mind if it's his only successful single.

He said: "I would take a sort of perverse pleasure if a certain part of the public think of me as a one-hit-wonder. I'd be in some good company."
