  • "Lancer" is titled "I'm The Bad Guy!" in the Music Shop.
• In the background of "ANOTHER HIM", static noises that were used in Giygas's theme from EarthBound can be heard.
  • Additionally, "Weird Birds" is likely a reference to the unorthodox leitmotif heard throughout EarthBound's soundtrack.
• "Before the Story" originally debuted as a part of a dynamic theme for the PS4/PSVita versions of Undertale. The theme is named after Undertale's Ruins, and depicts Undertale's Home with Waterfall's light blue stars overhead.

• "The Legend" is the only song that changes time signatures during the song, from 4/4 to 6/8 near the end.
• "Lantern" plays 0.95x slower in-game compared to the official soundtrack version of the track.

  • "Hip Shop" plays inside Swatch's Color Cafe.
  • "Empty Town" plays before the Darkners from Chapter 1 are brought from the unused classroom and into Castle Town, after which the track "My Castle Town" plays for the remainder of the time there.

  • "The Chase" plays in Annoying Mouse Room 3 before Berdly shows up.
