Option to disable Piece of Power/Guardian Acorn music?

[Llammissar]

It's been annoying for decades so the ability to just make seeds less obnoxious about it would be nice!

EDIT: also the nag message for them, maybe?

Hard-mode removes them completely from the game, maybe that helps? (They interact a bit odd with the music system, so I'll have to see if I can come up with a patch that doesn't break things badly)
