In September 2011, Facebook began letting users see what music friends were listening to on the popular streaming music service Spotify. The social network announced today that it will soon roll out the next part of its music service.

The “listen with” feature will allow users to listen along to what friends are playing in real time. Users can also listen together in a group while one friend plays DJ. To see which friends are listening to music, look for the music note in the chat sidebar. Hover over their name and click the Listen With button. The music will play through whichever service that friend is using.

Users will also have the option to chat about what is playing and as more people start listening, a group chat will begin. Because of this, the social network has also introduced some new privacy settings to go along with the new feature. “Only the people you’ve shared your listening activity with can see when you’re listening with a friend,” states Facebook in its Help section.

Privacy settings can be controlled through the App Settings page after installation. Users can also remove songs that have been listened to from their Timeline through their private activity log.

This feature is great for musicians and other music related businesses as it increases awareness across the social network. As an individual starts listening with friends, he or she can also discover new songs or artists that might have gone unnoticed otherwise.
