WOW, the bulk of my listening falls into this category.
Aerosmith: Get Your Wings
Asia: Pick a song from the SECOND album.
Black Sabbath: I MUCH prefer what I call the "prog years" (SBS - Never Say Die) over the "classic years" (S/T through Vol. 4)
Cheap Trick: All Shook Up
Deep Purple: LOVE Fireball, and actually enjoy much off the first three (Rod Evans) albums
Genesis: I LOVE ...ATTWT and Abacab
Gabriel: I prefer the first one and US over SO.
Grateful Dead: I prefer Anthem Of The Sun and Terrapin Station over the "classics", American Beauty and Workingman's Dead
Iron Maiden: I prefer Dance of Death (and to a lesser extent The Final Frontier)
Elton John: Tumbleweed Connection and Breaking Hearts
Judas Priest: I LOVE LOVE LOVE Point of Entry. I think that's one of their best albums.
Kiss: Unmasked and The Elder are both favorites
Oasis: Be Here Now and Standing On The Shoulder of Giants (the more they channel the Beatles, the more I like them)
Ozzy: Other than the title track, I LOVE Bark At The Moon
Queen: Queen II is my favorite album, which doesn't fit here, but A Kind of Magic and Works are very close.
Rainbow: I prefer the three JLT records over everything else not named "Rising" (though Down To Earth is an underrated guitar album)
REM: Reveal and Document both slay the two "popular" albums (Automatic and Out Of Time)
Stones: Aftermath, Emotional Rescue
Rush: Caress of Steel, Presto
Scorpions: In Trance, Animal Magnetism
U2: How To Dismantle The Atomic Bomb
Van Halen: Diver Down is one of my favorite VH records, as is Different Kind Of Truth
Yes: Talk. Big Penetrator
I'm sure there are more that I'm forgetting.
