What risk has he took? Um, going from the Queens Bridge coke pushing k!ller to being a black empowerment, Pac-esque type of rapper. Those two don't really coincide with each other.
I gotta agree with this right here. While Nas and other "conscious" (hate this term) rappers may stay in their lane the same way Jay and other luxury rappers do (but I'm uncomfortable putting Jay in this category in the same way someone like Ross would be in it), being a conscious rapper means you're constantly talking about different topics. The lane itself is inherently more diverse than the luxury rap lane, which is stagnant as fu*k because you're really only rapping about one thing.
That said, Jay definitely has had diversity over his career, but the vast majority of his work is brag or luxury rap. He even admits the switch up on Moment of Clarity. Songs like You Must Love Me, that sh*t is incredible, that song touched my heart and I could relate to it, but Jay doesn't give you a lot of that because it doesn't make for number one records. He gives you maybe, one or two an album. Nas and other like-rappers, on the other hand, give you damn near full albums of that.
