[Feature Request] Vanilla Music gets slightly muffled if underwater or in a really deep cave

[Dashy22]

Might not be the best feature request but it would be cool.
Maybe when underwater it would also slightly muffle other sounds but I think that the music muffling would be the nicest.
And for the cave idea, I feel you would have to be below -30 to start being muffled and it shouldn't be as noticeable as water.
