Trivia
- It is possible that Twilit Waters and The Dark were originally meant to play in some of the cut biomes such as the Deep Arctic and Methane Ice Caves.
- By using the F1 debug menu, names for the tracks can be seen as they play. Most of these names differ from the final titles they were given on the album.
- Most of these in-game track names are very placeholder sounding, such as "Safe Cave 2", while other tracks have much more unique names, for example the track titled "The Void" is called "Spectre" in game.
- Most songs in-game were remastered closer to release, with a few tracks getting cut or having their purpose changed.
- For example, the track titled "Sam's Discoveries" on the album, was actually the Crystal Caves theme in earlier EA builds.
- The Deep Twisty Bridges initially had a song that was an early iteration of the track "Far Less Alone".
