or just simply good and bad music.
with genres usually comes an image associated with it. Those images usually go in and out of fashion, and so does the music thats associated with them.
Its like in the UK at the moment, nothing but these pussy indy bands playing in my local clubs, full of kids who go along in their trillby hats to be part of something, but in 10 years? will they still be walking around in a trillby hat, or wearing a new rave tshirt? no, dont count on it.
thats one of the things that warmed to this type of music (metal, to generalise), is because most of the people have a passion for what they listen to, and will keep listening to it, i mean, go to a metal gig, theres usually people from all generations that turn up.
to summarise, i dislike all these genres, because all it does is segregate the listeners tastes, if i told someone at a party, i listen to Rainbow, they'd probably say, oh really, and look at me funny, not really wanting to talk about my taste of music, or theirs, because they probably think my taste is weird, and not fashionable enough (basically trendy elitism), But if i said, I listen to led zeppelin, theyd probably go, oh yeah, great shit. Then id ask them what their favourite zeppelin album was, and theyd say, errrrrm that one with stairway to heaven on it.
to summarise again - Genres make people biased against music, for example, "i wont listen to this because its metal" but "ill listen to this, because i like the band T-shirts"
thats a pretty bad way to explain it, but i get it allot with my friends, who will refuse to listen to my music, in the car for example, based on the genre, name of the band, etceetc, before they even listened to a sample, then they say, your such a cynical bastard, when i say i dont like this fucking R&B, Rap, or watered down power choorded wank
