Not sure why most Fabric packs don’t have this mod but Etched would be a fun mod to have in AOF 5. It allows people to create their own music discs and either use in-game sounds (anything that shows up in /playsound) or importing music via Soundcloud/Bandcamp URL or MP3/OGG/WAV files. Imagine having a music collection in-game that everyone can listen to and can be used as a discovery tool. That’d be pretty neat.
