RIM's cloud based music service named BBM Music is currently undergoing limited beta testing and is expected to be available to BlackBerry users by the end of this year for a monthly subscription price of $5.PhoneArena has reviewed the application and provides some pictures and videos of BBM Music in action. The applications interface is divided into 4 tabs - Home, Profile, Connections and Store. You can share the songs you have added with your BBM friends much like the Spotify service allows you to share your playlists with your Facebook friends. While the BBM community is quite large, it will be nice to see this feature extended to other social networks like Twitter and Facebook in the future.
