Australia's Wally De Backer, aka Gotye, has won Record of the Year at the Grammy Awards.
It was Gotye's third Grammy of the night.
The Melbourne-based 32-year-old earlier won for best alternative music album and best pop duo/group performance.
Past winners of record of the year include Frank Sinatra, Michael Jackson, Whitney Houston, U2, Coldplay and Olivia Newton-John.
Somebody That I Used To Know, featuring Kiwi singer Kimbra Lee Johnson, has sold more than 13 million copies worldwide, was No.1 in 18 countries and in the key US market, it was the biggest selling single in 2012.
It sat on top of Billboard's Hot 100 in the US for eight straight weeks.
De Backer was up against The Black Keys, Kelly Clarkson, Taylor Swift and Frank Ocean for record of the year.
The Best Record award was one of three gongs for the Melbourne-based 32-year-old, who earlier won Best Alternative Music Album and Best Pop Duo/Group Performance
'I recorded it mostly in a barn on my dad's block of land southeast of Melbourne, Australia, so I have to thank Dad and my Mum for setting up a lot of weird equipment in a barn near their house,' De Backer told the crowd on Sunday at the 55th Grammy ceremony under way in downtown Los Angeles.
In the Alternative Album category, De Backer's Making Mirrors was up against Fiona Apple (The Idler Wheel), Tom Waits (Bad As Me), Bjork (Biophilia) and M83 (Hurry Up, We're Dreaming).
'I don't really feel worthy of being up here,' a surprised De Backer said.
In the Best Pop Duo/Group Performance Gotye was nominated for his global hit, Somebody That I Used to Know, which features Kiwi songstress Kimbra.
'I obviously have one major person to thank and that is Gotye, Wally De Backer, for having me be part of this incredible song and this incredible journey,' Kimbra said.
Somebody That I Used Know has topped the No.1 singles chart in 18 countries, selling more than 12 million copies worldwide since its Australian release in July 2011.
The hit was also the most downloaded song on iTunes of 2012 and the most streamed song according to Spotify.
The other nominees in the category were Florence + the Machine (Shake it Out), fun. (We Are Young), LMFAO (Sexy and I Know It) and Maroon 5 featuring Wiz Khalifa (Payphone).
Record of the year, one of the most prestigious gongs in the music industry, will be announced at the main awards ceremony about 2pm (AEDT) on Monday at LA's 20,000-seat Staples Center indoor stadium.
