I do. Basically the more I like a band/album the more it gets played. So most Pumpkins CDs get played quite a bit, Green Day CDs do well, I think one of my most played CDs is We Have Come For Your Parents by Amen. Then there are some bands/albums that I like but rarely bother to listen to, simply because though they're good I have other stuff that I prefer.
Quite often I try and look through my CDs and pick out one I haven't played in a long time though.
And then there a few duds I own which I'm quite happy not to listen to

They're literally just a few out of all 600+ though.
