Facebook Music to simplify streaming music access

Back in May, Facebook launched its official music element intending to implement new music functionality. However, an official outline of things to come has not been released yet. TechCrunch has posted some details regarding this matter based on its sources that highlight some universal music-access solution for Facebook users. Thus, Facebook Music is planned to become a new wave of adding all the music activity taking place on other music services – namely subscription services like MOG, Spotify and Rdio – into the Facebook stream. Thus, users will be able to play the music through their respective service and playlists on their profile wall. Apparently, the plan is to enable users to listen to music and playlists posted by friends using a different service. What are your thoughts on this?
