o when I imagine someone who likes noise music a lot, my first impulse is to think they must in some sense "enjoy unpleasant things" (an obvious category error)

The same things happen to me in reverse: I find industrial music (pop or metal) quite pleasing, but the whole point of industrial is to add factory noise (for example those typical of a sawmill) to otherwise plain music, so I at least can understand why as a genre it doesn't have a wide community of supporters.
