Another consideration: earworms. I find getting a song stuck in my head to be somewhat aversive.
Edgar Allan Poe puts it this way:
It is quite a common thing to be thus annoyed with the ringing in our ears, or rather in our memories, of the burthen of some ordinary song, or some unimpressive snatches from an opera. Nor will we be the less tormented if the song in itself be good, or the opera air meritorious.
You know the drill - If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
