shared music

I don't know what it is, but part of the joy of listening to a song on the radio is knowing that countless other people are listening to that very song at the same time. Say, for instance, I have that particular band's CD and can listen to the song being played on the radio at any time - I'll still feel a little bit more connected to the song if I listen to it over the waves along with everyone else. Even if I'm alone in the car or in my room, it still feels like a shared experience.
