I have to say, there are a few incredible games that I just cannot play because the callouts and/or music just drive me nuts. I happen to be one of those folks who gets music stuck in my head - I think it's called getting an earworm.
So for instance: Lord Of The Rings is a very good game and I happen to be a fan of the theme. But those callouts! "2 Souls of man!" "3 Souls of Man" . . . AARRGGH! And I had a Metallica, which I loved, but I really don't care for heavy metal music. So although I truly enjoyed playing it I'd turn the music off and listen to something else while playing it. THAT didn't last. Really detracts from the intended theme. Sold it.
What callouts/music have kept you from playing/enjoying/buying a game?
