Nightcore began in the early 2000s with a Norwegian duo who sped up dance tracks and raised the pitch, giving the style its name. The sound spread online in the 2010s through YouTube uploads that paired the remixes with anime artwork, which tied nightcore closely to anime and gaming culture. Fans began applying the treatment to pop, rock and meme songs of all kinds.
