This resource pack replaces MOST of the music in the game with Kevin Penkin's amazing Made in Abyss soundtrack. It also replaces the textures and item names of the record discs to fit with their new songs.
To my knowledge at the moment the only music not replaced is the creative mode songs.
You'll have to find out yourself which songs play where, but i've done my best to make them fit where they play as I didn't want their placement to be random and unfitting. The music disc choices were limited as using music longer than their original track will cut them off, so I chose songs which are the right length.
Here is a list the music disk songs and the inspiration for their art.
