VOID UPDATE
If this does not work, try removing the mod from your Afterbirth+ mods folder and relaunch the game, it should work, I'd recommend doing this anyway just in case.
If it still does not work, unsubscribe, completely uninstall PCIM and resubsribe.

Changes:
-The Void and Delirium Boss battle have classic themes, showcased in 39Games' latest video.
-Panning effect removed from Burning Basement, Flooded Caves and Dank Depths, sorry if I made anyone sick!
-All music track's volume modified to match a certain level.
-Small fixes.
