Album which you have listened to most?

We all have favourites and we all keep going back to them every now and then. Some maybe permanently lying next to our systems and have been for years.

Is there an album or two or three at the most which gets most of your attention and is played on your system most often? Not necessarily the best sounding but the one which you are emotionally attached to.

I thought I would ask for a single album but to make it easier for all you may name three of them.

If you have have had the album for more than five years, it qualifies for inclusion here.

The reason I decided to post this message is because I am interested in buying something interesting and if there are only ten people responding it means 30 albums for me to be on the lookout for.

Thanks a lot for your input (if you have read this far I know you will post your three albums also) :-)
Miles Davis "Kind Of Blue".
Pink Floyd "Dark Side Of The Moon".
Radiohead "Kid A".

So what if you feel kind of Blue, me too for a long time but in a good way. :)
I have a couple that I seem to listen to more. Paradise Theater by Styx and The best of The Doobie Brothers. For Styx, it's Too Much time on my hands and Doobies, pretty well both sides. Hall and Oates is up there as well.
