Gangnam Style was released in July 2012 by South Korean rapper Psy as a satire of Seoul's upscale Gangnam district lifestyle. Its music video, built around the now-famous horse dance, became the most-viewed video in YouTube history and the first to pass one billion views. The track's hooky electronic beat and comic choreography turned it into a worldwide dance craze, parodied by celebrities and politicians alike. Though the peak passed, the riff remains a go-to shorthand for instant party energy and early-2010s nostalgia in memes and short videos.
