I don't think so. Instead of playing anything, there is just no music in the shop. The store loop into and store loop are in the music file, and the metadata xml doc is in resources. The other mods I have installed aren't interfering and are in their own respective folders in the music file. Maybe the store loops need to be in their own folder?
Because this mod is Afterbirth+ only I believe.
Hit me up if you still have problems and maybe tell me what's wrong
You should get it if you get the chance. It's really good.
