Music is a pyramid.
An awful lot of dross at the bottom, that has you running in the opposite direction
A large middle section of stuff which is okay right time, right place, but you don't want to hear it too often
The apex of the pyramid is small enough already. If you start slicing off different genres, particular performers, particular styles, different national origns etc you end up not really liking much at all. What's left is less music, more a fashion accessory.
