I appreciate all the above mentioned forms of music as they all have their place, but for me personally I like powerful music. I don't dance, so I don't really care if it has a certain groove, although groove definitely helps. Metal is the most powerful music I can think of sonically, so thats pretty much what I prefer. But I also like music with emotion, like some instrumental electronic music and some mellow SRV every once in a while. But some music doesn't stir me at all, and thats pretty much what I wont listen to. Modern country is an example of this. Sure, sometimes you can relate to the lyrics, but theres nothing there musically (although there is quite a bit of musicianship in some songs). Pop also seems to have little to no depth to me, so I don't care for it much either.
