Pretty much every single band plays to a genre though. A metal band is obviously a metal band, and so on and so forth. Saying that genres are pointless is a bit silly, because everyone is working within some kind of confines and boundaries, whether they realise it or not. Just by picking up a certain instrument you are straight away narroing possibilities. And what is really wrong with opperating within a genre anyway? Even or bands who don't, if there music is shit, it is shit, even if it is unclassifiable.
