I had to give my vote to the underdog, Mecca & The Soul Brother. Mostly for nostalgic reasons, but that album is just as complete as any on that list. It's also just as unique, imo... even though on almost every song on the album, Pete Rock sampled the same artist... who is he...
I had to take Illmatic, although I'm kinda surprised Do You Want More had no votes. I fucking love that album. I've gone through 3 CDs just from playin' it out.
