Facebook has been releasing many music related apps and the sort, as of late. Their newest addition to “social music” is called “Listen With Friends”. How it works is you listen to a song on your music player (Spotify most likely) and your friends can see what your listening to. If they choose to, they can click on what it is your listening to and listen along with you live. I think this could be another great way to share music with your firends. I’m not sure how many people might actually use it, but it is a cool feature to spread music in real time.
