Interacting with a friend while he listens to a song

When I acess Spotify by the computer, I can see in real time the songs that my friends are listening to. It would be interesting to express reactions to these songs. The power switch also send a message to a friend would turn Spotify on a social network instead of simply a music player. Create a tab on the mobile app so we could see in real time what our firends are also listening would be something very interesting too.
