When it comes to controversial peer-to-peer
file sharing capabilities in using the fast track protocol, Kazaa Media Desktop is always the first thing that comes into our minds. Most of us are also aware that Kazaa is used to exchange MP3 music and movie files over the Internet. The official client of Kazaa is free of charge, and it is financed by Spyware and adware, even if the official site displays a "No Spyware" reminder. What makes it controversial is the number of copyright-related lawsuits filed against Kazaa. In using Kazaa, you will be able to search or download contents that are shared by other users of Kazaa or prime content providers.
