In terms of albums with no bad songs, Rammstein's Reise, Reise and Metallica's Ride The Lightning (well, except Escape).
Albums that only slightly miss the mark are Slipknot's Subliminal Verses (Opium of the People and Welcome) and Mastodon's Leviathan (I Am Ahab/Island).
I realize I'll get trolled but 21st Century Breakdown by Green Day only has one or two bad songs as well, and it's one of the few albums I can stand consistently listening all the way through.
...
Oh, shit, nearly forgot.

Best metal album ever made, IMO.
