Music is just "Broken Heart Of Ender" from Minecraft Dungeons 1. The song itself is for the bossfight in the Echoing Void DLC in the end dimension, which is filled with void, which is one of the reasons why I chose that specific song since Abyss is a "void entity", plus its the only song I could think of when I thought "music I could use for Abyss".
