Yeah, Diamond Dogs is the best.
I also think Lodger has a really cool cover. Recently I was in a student short film and my character had to get hit by a car, and when I was lying dead on the road, I tried to replicate Bowie's Lodger pose. Unfortunately the director told me to lie on my side, so the allusion was ruined.
Damn, just about all of Bowie's covers are bitchin'...Only ones to my mind that suck are LD, Tonight, NLMD and the two Tin Machine albums.
Love me and I will be your friend
Love me love me till the end
Until the occasion arises
Then I will kill you.
