Facebook is set to announce it’s digital music service which will post the music you listen to directly to your Facebook wall – friends can click and listen for free. 

Despite rumors swirling around the web Facebook is not building it’s own music platform. They have instead  partnered with online music services Spotify and Rhapsody, Rdio and MOG. This is an obvious win for Facebook as they gain access to another piece of crucial data to build onto your social graph. Instead of simply knowing what you claim to like via the information input on your profile they’ll actually know what you like based on the music you listen to. Users can also benefit by being able to join in and listen to that track for free. Publishers may then gain more sales as new music is exposed to a wider audience.

It’s being suggested that in addition to music, television shows and movies are planning on being implemented. Facebook will likely provide more information at the F8 Developers Conference happening in San Francisco on Thursday.

The downside of course is that unless Facebook has something up their sleeve, your stream is about to get really cluttered. Anyone remember MySpace and the poor poor horrible implementation of music on that social network?! I certainly hope this is something that can be disabled.
