Preferring game consoles to DJ booths, German producer TheFatRat made his name as a copyright-free music source beloved by gamers and YouTube creators around the world. • Before releasing music as TheFatRat, Christian Büttner made background music for TV, commercials, and radio under his own name. He also coproduced “Mignon Mignon”—a chart-topping 2010 French hit by the virtual singing mole René la Taupe—and rapper Lupe Fiasco’s 2012 track “Audubon Ballroom.” • TheFatRat’s 2014 single “Unity” typifies his signature mix of retro chiptune blips, highly produced electronic boom-baps, and annunciated vocals. When El Salvadorian YouTuber Fernanfloo used “Unity” in an intro, TheFatRat's popularity sky-rocketed. • Quite fittingly, TheFatRat’s music has been used in actual video games, including Rocket League and Dota 2.
