It shouldn't have been a double album, but I get it because Nas was in a creative zone at the time and he had to make it happen after I Am... was bootlegged. At one point, it was going to be a triple album.
There are six or seven songs that I think should have been left off and the album would have been perfect. Most of them are in the second half because the first half is almost flawless. I think this is the album where Nas officially gave the industry the finger and said that he was going to do whatever he wanted. It was the first time he went left and people didn't know what to make of it. Something I love about this album is how grimy it sounds. It just feels like an underground album that we weren't supposed to hear. It's the beginning of Nas' ambitious, conceptual period and it's his most overlooked period.
Also, I've said this before, but from a technical standpoint, it's Nas' best album. At least on par with It Was Written if not better. The last verse of "Street's Disciple" is one of his finest moments on the mic.
