I think musical stlyles and genres are the result of musicians limiting their range of aural input and practice to something they are familiar and comfortable with. Genres are limiting. Personally I think I am a rock guitarist cause I love metallic shredding but I'd rather aspire to being like a jazz player than being like a standard rock guitarist and I love jazzy scales and big weird chords. I'm sure similar thing happen for many musicians opearting within a genre, they're trying to get out of their pigeonholes and take flight as it were.

Usually I hate rap! But I heard a brilliant rapper locally who rapped really fast and really rhythmically and his lyrics were funny and thought provoking at the same time. What's going on then? Talent, that's all, the guy was great no way would I tar him with the MTV brush.

So basically I don't respect people slagging off entire genres at once, some players are better and some mix a genre you don't like with one you do like and pick up some hybrid vigour.
