lots of stuff posted that I agree with, OK Computer yes, DSotM, WYwH and Animals certainly, Rumors yep, but on the zep I'd go with
Houses of the Holy
and others for me are
Bringing Down the Horse - wallflowers
Are You Experienced - Hendrix
The Hissing of Summer Lawns - joni
Aja - steely dan (also Katy Lied, Pretzel Logic, and Royal Scam)
Living with the Law - Chris Whitley
Kind of Blue - miles davis
Born to Run. that's right. Born to Run is a perfect album.

and finally, I'm gonna have to agree with Bat Out of Hell.

(I'm sure my list of perfect albums, of which these are just off the top of my head right now and just a few of, is going to be vastly different than the "perfects" of others. I'm okay with that.)
