You're the Best was written by Bill Conti and Allee Willis and performed by Joe Esposito for The Karate Kid in 1984, where it played over Daniel LaRusso's tournament montage. The song did not become a major chart hit at the time, but the film's lasting popularity turned its chorus into shorthand for 80s motivational success. It has since been quoted and parodied across television, sports broadcasts and online video, and the short chorus loop survives on soundboards because a few seconds are enough for anyone to recognise the joke or the genuine hype.
