Undertale Complete OST

The Undertale Complete OST is a soundtrack album for Undertale, available on Fangamer. It includes every track from the original UNDERTALE Soundtrack along with eight additional tracks released afterward, for a total of 109 tracks. Most tracks were composed by Toby Fox, including cameos from Coda and Flashygoodness.

A subset of tracks from this album is available as Undertale Collector's Edition OST sold on two CDs along the Undertale Collector's Editions, also available on Fangamer. The track Mad Mew Mew is absent from this edition.

Official track list

The track list is divided into five LP records, each with an A and B side:

• LP1 Side A: Ruins (tracks 1 to 14)
• LP1 Side B: Snowdin (tracks 15 to 29)
• LP2 Side A: Waterfall (tracks 30 to 47)
• LP2 Side B: Hotland (tracks 48 to 63)
• LP3 Side A: Core (tracks 64 to 71)
• LP3 Side B: Castle (tracks 72 to 77)
• LP4 Side A: Hopes (tracks 78 to 85)
• LP4 Side B: Dreams (tracks 86 to 92)
• LP5 Side A: Determination (tracks 93 to 100)
• LP5 Side B: Bonus (tracks 101 to 109)

The additional eight tracks are placed in LP5 Side B. The track Song That Might Play When You Fight Sans has been moved from place 72 (LP3 Side B) to place 29 (LP1 Side B), and the track Menu (Full) has been moved from place 93 (LP5 Side A) to 101 (LP5 Side B) compared to the original soundtrack. These changes aren't reflected in the Collector's Edition OST.
