You're the Best was performed by Joe Esposito and featured in the 1984 film The Karate Kid, where it plays during the tournament montage as Daniel advances against the odds. Written by Bill Conti and Allee Willis, the song became inseparable from 1980s underdog stories despite receiving limited chart success on release. Its chorus later spread widely online in sports highlights, parody montages and motivational edits, where creators reuse the sincere, over-the-top encouragement to make ordinary achievements feel like championship moments.
