I discoverd the Free Music Philosophy by reading an article by Ram Samudrala on the mp3.com site.

The article was entitled "The future of music" 

I've been very impressed by the Ram's ideas, because they were exactly my ideas!!! So i began to follow the links that pointed to ram's site where this  philosophy is well explained.

But, what is FMP? In Ram's words:
"It is an anarchistic grass-roots, but high-tech, system of spreading music: the idea that creating, copying, and distributing music
must be as unrestricted as breathing air, plucking a blade of grass, or basking in the rays of the sun. "

If you want to know more, visit Ram's site following one of the links in this page. The link on the FMP logo points to the FMP "manifesto", but i think that the best point to start is the "The future of music" article.
