Well, what kind of music do you like? Good albums, as opposed to just a bunch of songs strung together, are kind of a special thing.

Might I suggest a Nick Drake album? He only made three (although there are technically more), and all of them have excellent full-album flow. It's folky and acoustic, so not to everyone's taste, but it's beautiful stuff. Alternately, a classic Pink Floyd album? Those are also very this-is-a-complete-album.
