I'm still on Kazaa. I have Kazaa Lite Resurection though, which is pretty free of spyware and shitty stuff. I had regular Kazaa before and it totally messed things up, but this version is fine.
get the simple version of limewire off the internet, then once you got it, click the 'programs' button and type in 'limewire pro' and download the real version you'd normally have to pay for.
