500 Greatest Albums of all Times

Yes, Rolling Stone Magazine is at it again with a new version of subject, that is on the newsstands now. Some think there is a bias in the list, others dismiss it as a marketing stunt. So my question is simple, and numerical, how many of these albums do you actual;y currently own, in any media form. All who answer with '500' will get to go to New York and be an unpaid intern at Rolling Stone for five years, no expenses paid.
