RIM With BalcBerry Music

Another music cloud base has appear and its BlackBerry Music. Doesn't want out from the competition from Apple, Android and even Microsoft, BlackBerry decide to launch its own music cloud. Details are sparse, but supposedly the P2P system will be called BBM Music and allow you to distribute songs and playlists amongst your BBM contacts. Obviously, there will need some sort of licensing system or DRM implementation (can't re-share tracks you got from someone else, for example) to prevent rampant piracy, but what RIM is thinking is not known yet. The subscription is $5 a months, but whats in the package is not known and also there is a 50 limit song, maybe for every user but payment means more?
