A playlist for the Roblox game Undertale: Last Corridor,  in wins order (of characters, not skins, exceptions being little hyper and little god) and including removed/unreleased tracks and singleplayer tracks where they're different. 
UFR Papyrus's theme was taken down, and I can't find it anywhere so I'll have to wait for an official reupload or risk copyright.

Undertale Last Corridor

The playlist has all of the ULC's original soundtracks, old versions of said tracks, and some fan-made tracks that I think would end up in the game or would fit.

Playlist Picture is taken from an ULC Illustrative Image in Roblox, I thought it would be cool.

going to either
1. archive this account and do my own thing on a new one
2. move the older songs to a new account and make it an archive

running out of uploads

This is a scrapped song I made while Epic was still hired, we were going to collab on it
Unfortunately I had to scrap it cuz of the drama regarding Epic + He got fired...
Will I remake this song from the ground up again? Maybe maybe not

This song was still heavily unfinished so that can explain why it just doesn't have any percussion at all

ULC - SHADOWS DIE TWICE (Scrapped)

Made by Epicified for LittleHorror Sans's RAGE phase.
Removed due to drama.

[LITTLEHORROR Sans] Crashout

Made by Epicified as a Lobby Track for the upcoming Casino Update.
Removed due to drama.

[THE CASINO] Lobby Track 5

Made by KnuckleDuster for LowTier Sans's second theme.
Was then used for LittleLowTier Sans.
Removed due to drama relating to the source inspiration, LowTierGod.
