Imo, Nas and Jay-Z. Nas comes into the picture because his unreleased discog is the best in hip hop history. At least from what I've seen. Lots of high quality records.
Jay-Z has bangers for days. You could easily do an "all Jay-Z" party and it wouldn't get boring.
Wu as a whole have a great discography, particularly in that 93-97 run. Mobb Deep have a pretty good discography as well, with some really dope unreleased shyt.
Those ones immediately come to mind. what do you think?
I disagree with your rankings for Nas's discography . But I guess that's a fair assessment.
