Tons of bands don't even have websites. Like Nicole above me said, who needs websites when Myspace serves all their needs and allows networking?
Anton, myspace is a great tool and can be very informative/comprehensive, HOWEVER, like other fads before it, myspace can become a thing of the past very quickly. This will leave a ton of bands in the dust with no official home on the web. A band's .com/.net will always be around and is permanent and will never go out of style.
