Kazaa [KAZAA] shares a similar history as
Napster [NAPS], with law suits, court trials, public file sharing network protocols and clients, and eventually becoming a legal on-demand music streaming service, with the option of unlimited downloads.
When you sign up for the 7 days FREE trial period, a credit card is required. It seems that you download song tracks with a "plugin software" and files are DRM-protected Windows Media Audio. Those *.WMA-files stop playing from hard disk drive when your subscription has expired.
KaZaA may be the worst online music subscription service i know with a tiny database of 1,000,000 song tracks. If someone wants to review it, leave some negative comments, or similar, please do so.
I dont feel tempted at all to test their service!!
