Napster was the best IMO, but those days are over. Morpheus came pretty close but now there new software and servers suck, IMO. After Morpheus I switched to Kazaa, but after learning about the spyware, I ran adware to remove D3B, cydoor and all the other crap included with Kazaa. After I did a system restore I tried Kazaa Lite, which is just like Kazaa but no spyware, BonziBuddy, popups or any ads period. I fully recommend Kazaa Lit, but as always make sure you have an antivirus program that updated and possibably a firewall just to be safe.
