De Vet Du (literally “You Know It” in Swedish) is a Swedish music group formed in 2010 mixing humor and sarcasm in their lyrics. The four friends Christopher Martland, Johan Gunterberg, Tor Wallin, and “DJ Hunk” (aka Fredrik Thernell) started the band in Lidingö, a suburb of Stockholm.

Originally they uploaded funny videos on Youtube, then moved to music and posted their first song “Dansa Är Kul (Men Jag Föredrar Å Supa)” (meaning “dancing is fun, but I prefer to drink”) in May 2010.
With further, quite often parodical titles and explicit lyrics, they released their debut album Shit Va Pin in 2012 under the label Universal Music Sweden and hit the Swedish charts. It was followed up by another charting single “Kär i en kändis” in 2013.
In 2014, they released their second album RadioMusik which also became a success in Sweden.

In 2017, they participated to Melodifestivalen 2017 (annual Swedish song contest), qualified for the semi-final with their song “Roadtrip” and released they third album: Skiprate.
