Also, unlike Napster, Scour Exchange keeps all its users on one central server, unlike Napster who has about 15 servers which have ~4000 users each. And yes, SX is awash in pr0n, but if you really need videos, try IRC, though SX's music selection is usually quite good. I think Scour has the ability to replace Napster, should Napster become stopped/banned, as other products like gnutella use too much bandwith with the decentralized server approach, and aren't nearly as well developed/easy to use.
