The Sparta remix began on YouTube around 2008, when editors started chopping Leonidas's 'This is Sparta' kick scene from Zack Snyder's 300 into rhythmic electronic tracks. The format, sometimes called Sparta remixes or Sparta bass, became a staple of YouTube Poop and meme edit culture, with thousands of versions remixing cartoons, games, and movies the same way. Numbered uploads like this one are typical of soundboards archiving individual remixes. The joke endures because the formula is endlessly reusable: take any dramatic line, chop it to a beat, and it becomes an anthem.
