One interesting aspect I find with music as opposed to other entertainment media is that the enjoyment level can actually increase each time you return to a given piece, and that you can return to them again and again and never get tired of them.

I've probably listened to the Beatles' "White Album" several hundred times (I'd say once every few weeks over the course of over twenty years), and I keep on finding new things to enjoy in it.

I doubt if I've watched my favorite movies more than about a dozen times each.
