I mean, anything can be a squick, I guess. Music is one of those things that I seem to be unable to avoid clicking on, even though 95% of the time it is super disappointing. So I guess it's not even a squick? But it will make me back out at the first sign of wrongness.

Those medical issues are the ones that like, annoy the crap out of me, but I can force myself to ignore them, if I enjoy something else about the show/fic/whatever. Can't do that with music, though.
