you could always try Kazaa, or the probably now-superior LimeWire, or bit torrent.
these 3 are the dominating forces in peer to peer sharing. you cannot get kazaa lite any more, which is kazaa but it loads faster and has no advertising etc. but you can still get the normal kazaa, always helpful.

I havent tried LimeWire but i hear good things about it, and even that it may be better then kazaa.
its just a shame audiogalaxy closed down.
