I stopped using Kazaa and all it's forms a few months ago. Now I use
Soulseek and find whatever I can off of
MP3.com. Soulseek is really good, you can't even compare it to Kazaa. It has a lot of "underground" and harder to find music while still having stockpiles of mainstream music. It also comes with chatrooms, which surprisingly, are very good. They have the odd moron come in now-and-then, but for the most part it's full of knowledgeable people.
Oh, in case you want to browse my files [when I'm online], my username is 'alexjs'.
