Reception[]

The soundtrack has been widely praised by games press and fans, with Eric Van Allen of GamingTrend saying, "The soundtrack to Undertale reinforces [the game's] earth-shattering moments, knowing just when to rise and fall, and the frequent use of melodies and themes subconsciously manipulates your heart throughout the whole experience. Each song is reminiscent of a time when melodies had to be simple yet discernible, and each piece finds a way to grow outside the realm of chiptunes without losing that simplicity."^[3] Jim Sterling praised the soundtrack as "a damn fine collection of unforgettable tunes."^[4]

Trivia[]

There are eleven tracks in total that are used in a diegetic context, being Memory, Spooktune, Spookwave, Ghouliday, Ooo, Oh! One True Love, Oh! Dungeon, Long Elevator, Barrier, Your Best Nightmare,and She's Playing Piano.
Song That Might Play When You Fight Sans and Good Night are the only songs that do not play in-game.
