But the Earth Refused to Die is the 97th track in the Undertale Soundtrack. It references An Ending and plays during the Genocide Route, before fighting Undyne the Undying. It's composed mainly of chanting, white noise, and a heartbeat.
- The title of the track is a possible reference to Chrono Trigger, where if the player is defeated by the game's final boss, they get a unique "game over" screen that reads "BUT... THE FUTURE REFUSED TO CHANGE."
- The song plays at a lower pitch in the game compared to the soundtrack version.
