This mod adds music from several Minecraft Series games like Minecraft, Minecraft Story Mode and Minecraft Dungeons.
It seems that the mod does not work when you do not own/have space age installed. it'll just error out on "Failed to load mods: Error in assignID: space-location with name "aquilo" does not exist. source: electric (damage-type)"
Hmm, I'll see what's wrong when I'm free. Anyway, thanks for your feedback!
Made a fix by splitting data.lua into two script versions - spaceage/no spaceage
