This is more of a question than a bug report.

I like the Terrafirmacraft music and I like the original minecraft music so usually when my pack updates the TerrafirmaCraft jar I go inside the jar file (with mc, midnight commands) navigate to assets/minecraft/sounds.json and set replace:false (instead of true).

Would it be possible to override this with a datapack or resource pack somehow or make it optional via client config? I've read the pages on datapacks, resource packs and sound.json on the minecraft wiki, but I'm not clear if I would be able to set replace:false after it has already been set to true.
