My old player only holds 9 CDs, so until I change a disk, the same music plays in the background continuously. It makes my music an evolving thing that normally gets constant, small changes.

Since I really only listen to music in the car I have one disc with about 50 files on it that I listen to over and over. And since I like them I don't seem to mind it. In the truck I have a 6 disc changer, so the first three discs are basically the same 50 songs :) and the last three locations are empty.

If I do get a chance to listen to music at work it usually is the same (though different than the 50 above) music.. a little more quiet but still very enjoyable.

When it's new, maybe. But I've got a 300 disk changer, so I normally just hit random. It's always an adventure in "name that tune"
