"Fight On!" first plays in the battle against the Air Buster, and is used for every boss battle in the game after it, excluding the multiple battles with Jenova, Hojo and Sephiroth. "Fight On!" also continues to play following the battle with Rufus at Shinra Headquarters, and continues until the "Crazy Motorcycle" sequence begins. "Fight On!" is the twentieth track of the Final Fantasy VII: Original Soundtrack first disc.
