Metallica - Master of Puppets. Definitely one of the top 3 metal albums of all time.
Clowns in the Sky-The Songs of MST3K. Nuff said.
Weird Al Yankovic - Bad Hair Day. Funny, even though it isn’t his funniest.
Alice in Chains - MTV Unplugged. Great.
I second most of the other choices, too.

I actually like Actung Baby even better than the Joshua Tree. It’s more sonically inventive, and still, 11 years later, nothing sounds like it. I can’t think of a single bad song on it at all, and it has about 6 songs that made the radio when it was relatively new. I consider it a work of real art, especially as the lyrics actually have some thought put into them.
Little Earthquakes
Under the Pink
From The Choirgirl Hotel
Venus- Live and Still Orbiting
by Tori Amos
The Gift by Scott Henry
Little Plastic Castle by Ani diFranco
Live Through This by Hole
Operation Ivy self-titled
August And Everything After by Counting Crows
Hmmm . . . okay, “I Want to Tell You” has GOT to be one of them. I must have listened to Revolver 400 times and I STILL don’t like that one. But what could the other one be? That’s a puzzler. I love all the rest . . . but which of them do I love the least? Hmmm . . . “Love You To.” I’m guessing that’s it.
Am I right, astorian? Huh? Huh? Am I? Am I? 
Another one I thought of is Jefferson Airplane’s Volunteers. There are too many albums from that era to list, frankly.
Frank Black - Teenager of the Year.
Sugar - Copper Blue.
Foo Fighters - The Colour & the Shape.
Joni Mitchell - The Hissing of Summer Lawns.
Cibo Matto - Viva! La Woman.
Plus another vote for Siamese Dream.
I’ll add Counterparts and Moving Pictures to that suggestion.
90125 and Close to the Edge, when Yes is concerned.
Ah! An as yet unmentioned band: Camel - Dust and Dreams.
I love MK’s Sailing to Philadelphia, but for me, it DOES have some bad songs, IMHO.
**Pink Floyd - Wish you were here
Savatage - Streets (A Rock Opera)
Queensryche - Operation Mindcrime** (Can’t believe I’m the first!)
Whale Music - Rheostatics
Melville - Rheostatics
Sustainer - Starling
Clear - Danny Michel
King Cobb Steelie - Junior Relaxer
(…Just adding a little more of the Canadian feel to this one!)
DSOTM - Pink Floyd
After the Gold Rush - Neil Young
The Yes Album - Yes
“Slanted and Enchanted” by Pavement
“No Control” by Bad Religion
“The Clash” by The Clash
I forgot to mention, even though I like to consider my taste in music eclectic my dirty little secret:
Ride the Lightning Metallica
With all of the music I like; New Wave, Post-Rock, Hip-Hop, Prog-Rock… Actually Loving a Metallica album, as in “Gawd damn, that rocks” is kind of embarrasing.
Play Moby
I’ll re-nominate 7:[ol][li]hardygrrl’s: Nevermind: Nirvana[/li][]Angband’s, dead0man’s & astorian’s: Paranoid: Black Sabbath[]Caprese’s: Sentimental Hygeine: Warren Zevon[]FlyingDragonFan’s: Meddle: Pink Floyd[]easy e’s: Play: Moby[]Jello’s & astorian’s: Animals: Pink Floyd[]Ferrous’s: Aja: Steely Dan[/ol]And raise you 7:[ol][]We’re Only In It For the Money: Frank Zappa & The Mothers of Invention[]Nighthawks At The Diner: Tom Waits][] Ball-Hog or Tug Boat: Mike Watt & Friends[]Fly Like An Eagle: Steve Miller Band[] Black Sabbath: Black Sabbath[] Rock & Roll Animal: Lou Reed The Howlin’ Wolf Album (aka: The Dogshit / Birdshit / Psychedelic Album: Howlin’ Wolf No Purists scolding please, it was the 1st “blues” LP I ever owned…$2 in a used record shop, played it til there were no grooves left and lament the fact MCA won’t issue it on CD…must be a stipulation the Wolf’s will[/ol]
I second Copper Blue, Fishbone, The Clash, and London Calling. Here are a few more:
Devil’s Night Out by the Mighty Mighty Bosstones.
Hello Rockview by Less than Jake.
24-Hour Revenge Therapy by Jawbreaker.
Without my CD collection in front of me that’s all I can come up with right now 
This is Leechbabe’s lesser half Leechboy posting -
Charles Mingus - Blues & Roots + Mingus Ah Um
Nick Cave - No More Shall We Part
Dead Kennedys - Fresh Fruit
Bad Religion - Against The Grain
Tom Waits - Heartattack and Vine.
Black Sabbath - Self Titled + Sabbath, Bloody Sabbath
Chet Baker - Sings
Chris Wilson - live at the Continental
Bob Dylan - Blood On the Tracks + Highway 61 Revisited.
Jack Kerouac and Steve Allen - Poetry for the Beat Generation
Slayer - Reign in Blood
Motorhead - No Remorse
Kruder and Dorfmeister - The K & D Sessions
There are four that leap out at me, and, by some strange coincidence, all happen to be made by the same band:
*The Velvet Underground and Nico
White Light / White Heat *(Okay, I’ll grant you, “The Gift” kinda gets old)
The Velvet Underground
Loaded
Lou Reed’s Transformer almost makes the cut, if not for that silly “Makeup.”
IMHO, the aptly titled, “Fluff” is the one major impediment that prevents it from attaining the “album with no bad songs” classification.
Even if Mr. Meehan had left Fluff on the cutting room floor, Looking for Today & Who Are You, {though listenable}, would probably be considered minor speed bumps to “classic album” status.
Angel Dust - Faith No More
California - Mr. Bungle
OK Computer - Radiohead
Pet Sounds - Beach Boys
Revolver - The Beatles
The Director’s Cut - Fantomas
Buck Fever - Estradasphere
SCIENCE - Incubus
That’s all I can think of right now…
I add a some not listed yet and both fall into the what are they doing now list.
Supertramp-Even in the Quietest Moments and Breakfast in America.
Peter Frampton-Frampton Comes Alive. Just bought the CD a few weeks ago.
And what amazes me most is no one have mentioned The Beach Boys Pet Sounds. I have never been a big fan of TBB but this whole album is great.
My choice for the best album ever (Genesis - Selling England by the pound) does not even qualify, because of the More fool me track…
Albums where I like all the songs, and also some tracks are really special:
Al Stewart - Year of the cat
Kate Bush - Hounds of love
Meatloaf - Bat out of hell
Pink Floyd - Wish you were here
REM - Reveal
Tori Amos - Little earthquakes
and the absolute winner:
Bryan Ferry - As time goes by
