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: "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."

Meanwhile, analysis company Neilsen SoundScan revealed Adele's 21 album was the biggest selling in the US for the second year running, with 4.41 million copies sold in 2012, following from 5.82 million in 2011. The album has not left the US top 40 since its release in March 2011. In second place for US album sales in 2012 was Taylor Swift, with her latest, Red, followed by One Direction's debut album, Up All Night in third.
