Spotify Volume Fun!

I was talking with a friend about how cool it would be if people could see how loud you are listening to music if you click on their name, it could be visible along with the song, so people know how much of a jam it is (or yknow, wether they will hear your notifcation or not)!  Soundcloud and Bandcamp would be cool, maybe windows media player and groove would be kinda cool as well!
