Burn in Despair!

Every time you die, your grip on this world slips away.
Every time you die, your friends forget you a little more.
Your life will end here, in a world where no one remembers you...

Asriel Dreemurr during the second phase of his fight

Burn in Despair! is the 88th track in the Undertale Soundtrack. It is a faster and more heavily action-oriented remix of You Idiot. It plays during the first part of the second phase of the boss fight with Asriel at the end of the True Pacifist Route. The soundtrack version is slightly faster than the in-game version.

Trivia

• This track's beat was possibly inspired by the guitar section of Pokey Means Business!, or Cease to Exist in Japan from EarthBound. It could also be inspired by the song The Oracle from Secret of Mana. Notably, Toby Fox has referenced both games in previous songs he has worked on for Homestuck.
• The game's audio file is the shortest, though Long Elevator is shorter in the OST.
