MAIN THEME (MENU MUSIC)
In the Little Nightmares 2 files, multiple variations of the main theme can be found. The earliest version is distinct, featuring a different key and arrangement. The second version begins slightly earlier and includes changes in the choral arrangement during the third part. Additionally, there are separate stems from another rendition of the main theme, which is closer to the third part of the first version, yet completely different.
Wilderness
This audio file can only be found in the files of Little Nightmares 2. Judging by the name, it was probably an early version of the wilderness theme. The Nome theme motif is present in it, So i imagine it's probably related to that one concept art of the nome treehouse. It's a track made up of low-pitched, resonant tubular bell chimes.
tOGETHERNESS
A slightly different version of the theme "Togetherness," which plays during Mono's encounter with Six, in the files. This rendition is featured in the Gamescom 2020 Gameplay Trailer for Little Nightmares 2 and can only be found in the soundtrack release, but one semitone lower pitched.
HUNTER'S THEMEs
There is a completely different version of the hunter's chase theme in the files, under the name of "HuntingGrounds". There are separate stems of that track in the files of both the demo and the final game. The audio above is a mix of all of those stems. There is also a different version of the stinger that plays when the hunter is shot, being the only difference the presence of the fly swarm sound near the end.

SIGNAL TOWER'S PULSE

(Mus_TowerPulse) is a codename for the old version of Disposable Entertainment, which is the track that usually plays in every single Signal Tower scene. There are three versions of this track in the files. The first one has five stems separated in the files, but in the first audio file i mixed them together. The second one is slightly the same as the final one, except that the "chorus" isn't as intense and the synth bass at 1:00 is..odd. The third version is closer to what we got, except that the Boy Choir is way louder than the rest.
