Joe Esposito recorded You're the Best in 1984, and it became closely linked to The Karate Kid, where it accompanies Daniel LaRusso as he prepares for and competes in the All Valley Karate Tournament. The song was originally written for another boxing film before finding its home in the karate story, which helped cement its association with training and perseverance. Since then it has been reused in sports coverage, commercials and online edits, where its instantly recognizable chorus signals an underdog rising to the occasion.
