I'd like to mention some that haven't been yet. (although CTTE is correct to be mentioned IMHO and I would have had it not been already)
(no particular order, criteria are good songwriting and clean execution)
any Sade album
DT: ADTOE and DT12
Yes: Drama and Fragile (CTTE as well, but everyone mentioned it already. Still great though)
Genesis: Foxtrot, Selling England and Duke
Kraftwerk: Autobahn, Radioaktivität, Die Mensch-Maschine and Tour De France
Kate Bush: The Dreaming and Hounds Of Love
Billy Cobham: Spectrum
any Toto album (apart from Toto XIV, thanks Carlock)
Steely Dan: Gaucho and Aja
Return To Forever: Hymn Of The Seventh Galaxy and Romantic Warrior
Herbert Grönemeyer: Sprünge, Bleibt Alles Anders and Schiffsverkehr
Phil Collins: Face Value, Hello I Must Be Going and But Seriously
Tears For Fears: The Seeds Of Love
Sting: The Dream Of The Blue Turtles and Ten Summoner's Tales
(these are some that came to mind right away)
