I thought this was an interesting label to put on people as well. It reminded me of people I know that are the antithesis of "music lovers"-where a music lover looks for what is new and cool, trying to know about new music others haven't heard yet, a music hater has a narrow view, only listening to what they know they will like, deliberately not seeking out or listening to music recommended to them. It may not be accurate, but in a way it is "music hating".
