I mentioned Mac Miller in another thread and it made me think about his posthumous album. It's the only good one I can think of off the top of my head, but they really knocked it out of the park. The people who finished the album clearly cared deeply about him and didn't want to just ride his name into the ground for cash. They didn't even want to overshadow him, with details such as uncredited background vocals from Ariana Grande on one of the tracks.

The album also kicks ass, and can consistently make me cry with songs like Good News and Everybody. His death also makes the lyrics of the album hit so much harder, like I said Good News makes me bawl my eyes out on the right day.

Are there any other posthumous albums that were this good?
