Gotye and Carly Rae Jepsen look set to top the list of music acts with the UK's best-selling singles of 2012.
While the official list of the year's top singles has yet to be compiled, The Official Charts Company reports that Gotye and Kimbra's Somebody I Used To Know is already the top selling single of the year, being the first track to reach the one million sales mark in the UK earlier this year.
Carly Rae's single Call Me Maybe, which has also sold a million copies, is on track to be the second biggest selling song of the year, with fun.'s We Are Young featuring Janelle Monae tipped to take third place.
David Guetta's Titanium, Nicki Minaj's Starships and Jessie J's Domino have also sold well throughout the year and are expected to make the top 10.
Meanwhile, Cheryl Cole has finally hit the million sales mark with her debut solo single Fight For This Love - three years after it was released in 2009.
The Official Charts Company's managing director Martin Talbot said: "Many congratulations are due to Carly Rae Jepsen and Cheryl Cole, who have joined Gotye to make it three million sellers this year.
"The fact that there has still only been 125 million sellers over the last 60 years indicates just quite how impressive a landmark it is to reach."
