DAMN is easily #1 and it's not even close, from the quality alone, not to mention the impact, sales, influence (i hear alot of kendrick on this rapsody album) etc.
4:44 would be 2nd on the list, another album with great production, content, bars, which are all things this Rapsody album has but Jay's is more introspective and personal, so we know the characters he's speaking of , which makes the lyrics that much more vivid.
Then would be Rapsody's album and Drake's. You can say what u want about homie, but the nigga makes dope music. It might not be as "Lyrical" as the one's previously named, but sonically it's great.
Sean's and Joeys albums are right behind the 4 mentioned.
