Gangnam Style by South Korean artist PSY was released in July 2012 and became a worldwide phenomenon through YouTube, where its music video was the first to pass one billion views. The song's electronic beat and signature horse-riding dance spawned countless parodies, flash mobs and reaction videos. Short clips spread as meme sounds because the hook is instantly recognizable. More than a decade later it remains one of the most reused viral dance tracks for goofy, high-energy memes.
