Actually ad aware will NOT get rid of that particular problem with Kazaa so I highly suggest you get that program off your system asap.
Lately I've been using Audigalaxy (not too bad), Blubster (my favourite so far) and Mirc.
As for mirc channels I pretty much only use one since its the only place (for the most part) to get the tunes I like. Its on Dalnet under #stonerrock .
