You're the Best was recorded by Joe Esposito and became famous in 1984 when it soundtracked Daniel LaRusso's tournament montage in The Karate Kid, after originally being considered for Rocky III. Its association with training, determination and a final victory stuck, and the chorus was later lifted out of context for short online videos, sports highlights and reaction edits. Because the melody is instantly recognisable even without the film, it still signals an underdog triumph in just a few seconds.
