In a recent press release Sony dumped quite a surprise: Playlouder MSP and Sony BMG are teaming up to form a peer to peer music swapping network, that will put the substanial catalog of music already held by Sony online for all to share. This isn't a free ride, however. Though apparently all music on the network can be downloaded and traded at will, there is a subscription fee that goes along with it plus very heavy auditing and fingerprinting. The article calls it a walled garden. For those into legal file swapping, this looks like it may be one of the best bets so far. A very large collection that will grow fast, let you download as much as you want, and still keep the big boys happy. With all P2P though, this is sure to cause controversey.
