Ok, Ive tried just about every P2P software thier is out there. And hands down winmx had the best selection of music anywhere (you could DL full albums and live show). The key word was had cause it all changed a couple of weeks ago, cause now they don't have shit. I dont' know what happened or where everyone went but everything was gone. Anyways Kazaa lite is good but full of spyware and viruses. The latest thing I have been using is Shareaza. Its a new P2P program that searches a bunch of networks including Edonkey, Gnutella 1 & 2, morpheous, and even some kazaa hubs. I stongly recommend that everyone DL's 1.9 beta and checks it out:
