Sometimes it's a form of love just to talk to somebody that you have nothing in common with and still be fascinated by their presence.

You can know or not know how a car runs and still enjoy riding in a car.

You create a community with music, not just at concerts but by talking about it with your friends.

I couldn't talk to people face to face, so I got on stage and started screaming and squealing and twitching.

I notice when I'm at a party where I don't know anybody - even if I have nothing in common with somebody - we can still talk because we were raised by the same TV and cartoons and movies.

With pop music, the format dictates the form to a big degree. Just think of the pop single. It has endured as a form even in the download age because bands conform to a strict format, and work, often very productively, within the parameters.
