OI... I'm a rock music fan - love all those ones you've listed (except Prince - not my cup of tea at all lol) but I also listen to other things. While rock music is my music of choice, I've been known to play all sorts of other things - including the odd bit of rap which, although not a favourite of mine I do find some of the lyrics clever and one of the boys listens to it a lot.
Personally even though there are some genres of music which I really dislike and personally think is "crap" or whatever, I also believe that we
need all these different genres just to keep music moving forward and without all the various types of artists - be they sex gods like Aerosmith and the Chillis - or gangsta rappers (none of whom I can name LOL - in fact the only rap artist that I can currently think of is Eminem - whose lyrics crack me up at times) we would be in a dire place indeed where music is concerned.
(the only people that should be shot are the manufactured pop bands

)
