The latest entry in the series of mods that changes music to that dumb meme song

You just install it like a regular mod, but here's a guide anyway:

VANILLA AND AFTERBIRTH
1. unpack the file
2. click on folders until you find a folder named "music"
3. copy that
4. go to Steam\steamapps\common\the Binding of Isaac Rebirth\resources (somewhere in one of your Program Files folders)
5. just paste the folder in there

AFTERBIRTH+
1. unpack the file
2. copy the folder (not the one that ends with ZIP, the one inside)
3. go to Documents\My Games\Binding of Isaac Afterbirth+ mods
4. paste it in there
