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.
