Is Reasonable Doubt the most divisive album of all-time?
The truth is that in real-time, it was an afterthought. I still can't understand how people debate that. However, it did speak to a certain type of hustler that were waiting for something like that. And people that bought it, also liked it. These are also truths. Chicks liked it because of Ain't No Ninja, a couple of other tracks the average hip-hop head liked - pretty much the same tracks that Mega mentioned. However, most people didn't think Jay-Z was anything special at that time as a lyricist, not in wittiness, stories, flow. This is said not only by the hip-hop listeners, but dudes in the industry as well. Listen to Clark Kent tell stories of how "such and such" weren't feeling Jay-Z, and how was one of the few believers.
And yes, Jay did go on a campaign to elevate the album's status. Who he became also helped elevate it. Hell, if he did the same for Vol 1, people would agree there as well.
