This mod replaces every single song in The Binding of Isaac: Rebirth (+ Afterbirth DLC) with appropriate songs from the Crypt of the Necrodancer soundtrack by Danny Baranowsky, A_Rival and FamilyJules7x. Also includes fan mashups from Xeni Kobalt.

Installation:
Put the contents of the archive in "steam/steamapps/common/The Binding of Isaac Rebirth/resources".

I used music.xml so it won't be compatible with other mods that use music.xml.


The best part of this mod: FLOOR MUSIC HAS SHOPKEEPER SINGING AS LAYER!
