Best Hip Hop Album of All Time?

So I woke up this morning and felt like starting a huge fight via Facebook. Naturally, I plan on doing so by asking the people what the greatest hip hop album of all time is. I'm not even going to give my opinion on this subject because I don't wanna sway anyone's opinion in one way or the other. I just really want to know what our listeners think. What do the people of the 432 consider the greatest hip hop album in the entire history of the genre? I don't even want to name out artists for fear of having a small impact on how this all goes...also I don't want someone to call my ass out lol. I can safely say that I don't think Vanilla Ice is gonna win this one. I think that's a pretty safe bet at the point but you never know. In his defense, he did write possibly the most memorable song in rap....sadly.
