This mod adds R.E.D.M by VHS Dreams as a standalone track in the menus and in game.

To use this mod, you will need BeardLib and its Music Module addon:

Beardlib: https://modworkshop.net/mydownloads.php?...&did=14924
Music Module Addon: https://modworkshop.net/mydownloads.php?...&did=18107

Install those mods like you would any other BLT mod, and then add this mod to your assets/mod_overrides folder (Create this folder if it doesn't exist)
Once installed, the song will appear in the menu, same as the game's default songs.
