Trivia

• The tracks Dump, SWORD, NORTHERNLIGHT, GLACEIR, BIT ROOTS, ERAM, BURNING EYES, Hammer of Justice, Volume Adjustment, Catswing, AIRWAVES, and Concert for you are not visible on the Bandcamp release of the soundtrack when viewing the store page, but when purchased the tracks are present when played through the collection or when downloaded. They are always visible in the Steam, Apple Music, and Spotify releases at all times.
• The titles of some of the tracks from Chapter 4 only capitalize the first letter of the first word (sentence case), rather than using title case like most other track titles. These tracks are Old wooden rafters, Another day in hometown, The distance between two, Wise words, Piano that may not be played that well, Need a hand!?, The place where it rained, and Concert for you.
• The Japanese titles of Flashback (Excerpt), Sandy Board, Adventure Board, Query?, Board Clear!, Paradise, Paradise, SOUTH OF THE BORDER!!, KING OF ROLYPOLY, Big City Board, Doom Board, TV WORLD, It's TV Time!, Breath, Black Knife, Dump, SWORD, NORTHERNLIGHT, GLACEIR, BIT ROOTS, ERAM, BURNING EYES, C, ATRIUM, From Now On (Battle 2), 12am, 13am, Dark Place, SPAWN, and GUARDIAN are written in English.
• Like some of the other Chapters in Deltarune, Chapters 3 and 4 use a few tracks directly from Undertale without including them in its OST.
  • Confession is used during Lanino and Elnina's resolution at the end of the battle with Rouxls Kaard.
  • A version of Live Report, cut short to remove Mettaton's leitmotif, plays during one of Tenna's game show sequences.
  • Tenna's dialogue is occasionally accompanied by musical cues, two of which are brief samples of Fallen Down and His Theme.
  • In Chapter 4, a bitcrushed version of Tem Shop plays when Kris is prompted to imagine the Knight, only to imagine Jockington and Temmie instead.
  • Thundersnail plays while racing the Annoying Dog up climbable pillars in the 3rd Sanctuary.
