add an option with the others that goes something like "Replace 11 disc with the sound of nothing" which would basically fix any double playing music some people tend to have.

This is the thing I've came up instead of looking for conflicts and it works out really well, I mean the only bad thing is that disc 11 is soundless but who listens to that disc anyway lol

Also I just thought, since this wasn't responded to, I might add that how about some kind of preset saving?
So if someone wants to update datapack they don't have to setup everything from zero
