The Gray Album is really addictive. I think I'm most fond of "Encore" (which segues nicely from "Glass Onion" to "Savoy Truffle" halfway through) and "December 4th" (which samples "Mother Nature's Son," I think). And the fusion of "Helter Skelter" with "99 Problems" is so compelling that I'm having trouble imagining either song any other way.

The only annoying part is that I no longer own a copy of The White Album for purposes of comparison. In the old days, the solution to this problem would have been as easy as a trip to Dave's room.
