Gnutella, or some other freeware, will be up tomorrow taking its place. And the next generation won't make the mistake of a centralized server. These next guys will design something that has nothing to do with ownership, and therein lies the crux. At base this has very little to do with distribution channel rights. At base this is fundamentally about the nature of intellectual ownership.
Intellectual ownership is something that musicians take for granted.
For some reason, these guys assume that after they release their new CD, every copy bought should generate revenue. Face it, the only reason they believe it is because they know no other way. The constant stream of revenue via a distribution channel is an assumption that doesn't hold up to scrutiny. The underlying belief is that a creative product, once created, should receive payment for every copy. Picasso got paid once for selling his paintings.
