Custom Music Resource Pack Not Working

[RSNightKing]

Game Version 1.20.1

Forge Version 47.3.7

Mod Version 1.1.1

I was attempting to replace the ender dragon (Jean)'s battle music from the MC Dungeons Enderman to custom music from a resource pack, and it didn't appear to be working. The music plays fine when using the playsound command, but the music doesn't start when I get near Jean. The music is under the path minecraft:music.the_end_at_hand

I have linked the resource pack below.

Thank you for your time.

I don't know why, but only his built-in music works in the mod, that is, to make it work, you need to replace the original in the mod with your own... honestly, I tried to ADD custom files in every way, but they refuse to work. So for now, just replace unused tracks for other mods with your own.

it’s because the latest update attempted to account for neutral mobs, but broke everything else eg. the wither has no boss music, neutral mobs still don’t even work, among a few other issues. I’ll be releasing a patch once I have time to work on it again, which should be soon.

Apologies, and if you want to fix the issue I’d suggest trying to downgrade the version you’re using.
