The album features original score composed by Hans Zimmer and John Powell, and a cover of the disco song "Kung Fu Fighting" performed by CeeLo Green and Jack Black (who also plays Po, the lead character).

About the opening cue, "Hero", he called it "a wistful flute-led melody that sounds nearly identical to Howard Shore's "Hobbit" theme from the Lord of the Rings trilogy.

"[11] Writing for the website Film Music Institute, Adam DiTroia said "Kung Fu scores tend to fail when they try to hit every punch and kick, and Zimmer and Powell are smart enough to go for a cumulative wallop instead of going for every action move.
