Not a Major issue here, just wanted to bring to your attention that any music disks added by data packs and not mods will be converted from the music disk u had to C18's 11 music disk. If it can just hold and remember nbt data I'm pretty sure they'd work properly with data pack disks.

Hey! Thanks for reporting. Can you please link the datapack you have this issue with? Thanks!
