Well if you have been looking for g-d's personal p2p program; you have found it.
%100 legal, %100 free. No spyware or malware. They have all 4 major record labels on board as well as many smaller niche labels. This results in a library with 25,000,000 songs. Bigger than iTunes library, by a lot. In fact its 5 times bigger.
So how is this possible? Based on the number of songs you download, you are bombarded with a variety of different in-program ads. They are all contained within the p2p program so no spyware or malware gets onto your computer. I'm sure they have some tricky method of making sure you watch the ads; such as if you minimize the program the downloads pause. And i believe they limit the amount of simultaneous downloads to 5-10 at a time; but who cares? Its free, its legal, and its the biggest music library available on any program legal or not.
