I dont know about the cookies blockin, but blubster doesnt install any sptware, its spyware free. Working version its 1.2.3
there is a new vesion (2.0), still beta, but will be finish soon....yes blubster have some pop ups, but as long as you register you can block them (yes register is free also) . Downloads are fast lots of mp3 although is still a growing community, 10,000-12,000 people online mostly. I have use from napster to grokster etc and the one i really like for mp3 its blubster, the only thing need it is more people online!!!!
