Somebody (2024) Video (MV)

Somebody That I Used to Know is a song written, produced and performed by Belgian-Australian musician and singer Gotye, featuring vocals from New Zealand singer Kimbra. The song samples Luiz Bonfá's 1967 instrumental song "Seville", with additional instrumentations of beats and a xylophone playing a melody based on "Baa, Baa, Black Sheep".

The song was released in Australia and New Zealand through Eleven Music on 5 July 2011 as the second single from Gotye's third studio album, Making Mirrors (2011). It was later released by Universal Music in December 2011 in the United Kingdom, and 20 January 2012 in Ireland and the United States. "Somebody That I Used to Know" was written and recorded by Gotye at his parents' house on the Mornington Peninsula in Victoria, Australia, and is lyrically related to the experiences he has had with romantic relationships.

Commercially, "Somebody That I Used to Know" was a global success and became both artists' signature song. It reached the top of the charts in Australia, New Zealand, the United Kingdom and the United States, as well as 25 other official charts, and reached the Top 10 in more than 30 countries.

It was the most commercially successful recording of 2011 in Flanders (Belgium), the most successful of 2012 in Canada, Israel, the United Kingdom, the United States and Wallonia (Belgium), and the most successful of the 2010s decade by an Australian artist in Australia. It is certified multi-platinum in ten countries, including Diamond in Australia. Globally, "Somebody That I Used to Know" has sold more than 20 million copies, becoming one of the best-selling digital singles ever. In addition to the Hot 100, it was also placed at the top of Billboard's Year-End Adult Top 40 and Alternative Airplay charts, and many other charts around the world. On Spotify, the song has been streamed more than 1.7 billion times.

In 2024, Gotye and Kimbra released a remix of the song alongside Fisher, Chris Lake and Sante Sansone.
