No more free mp3s?

The recent cascade of law suits started by the RIAA (Recording Industry Association of America) and targeted at individuals uploading or downloading considerable amounts of copyrighted material over P2P networks, surely made a lot of people think twice before searching and downloading new songs from networks like FastTrack. With this unpreceeded number of lawsuits, and the ambitiousness with which the RIAA is trying to end this phenomenon, the future of file sharing is certainly a bit cloudy. Without the massive amounts of mp3s and videos, I doubt that these P2P networks could be of any use to anyone. Some claim that P2P Radio Networks will become the next attraction, as they would allow people to host their own radio shows without illegal bindings, but it isn't that sure that after removing illegal file sharers, people will consider themselves forced to buy CDs or online mp3 subscriptions.
Hundreds of individuals have been sued, many of them settling without trial, as the RIAA is using the controversial method by which it can subpoena an individual or ISP, without any court order and can then demand the identity of the user.
