Off the top of my head...
Van Morrison - Moondance
The Who - Who’s Next
Counting Crows - August and Everything After
REM - Automatic for the People
TP & the Heartbreakers - Damn the Torpedoes
The Stones - Exile on Main Street
Dave Matthews - Under the Table and Dreaming
Crosby, Stills, & Nash - Debut
Adele - 21
Jim Croce - You don’t mess around with Jim
Compilations are cheating, but if original soundtracks aren’t then:
Vangelis - Chariots of Fire soundtrack.
And a bunch already mentioned.
Can't believe I forgot this one:
Fleetwood Mac - Rumors
And a few others I thought of after a good nights sleep:
Los Lobos - How will the wolf survive?
The Police - Synchronicity
Van Halen - Debut
Billy Joel - Songs from the Attic
U2 - Joshua Tree
The Stones - Some Girls
Paul Simon - Graceland
Bonnie Raitt - Nick of Time
The Band - Soundtrack to the Last Waltz
And one that is always special to me because it was recorded in DC and features a local DJ (Don "Cerphe" Colwell) who was one of our favorites as kids. The other factor was how so many of the songs were so different live, and included the "Tower of Power" horn section; great stuff:
Little Feat - Waiting for Columbus
