OP is right.
Jay-Z's whole appeal is that he's the most self-aware rapper ever, to the point of fulfilling self-prophecy. Why do you think people caught such a chill off "U Don't Know?" That song is the essence of Jay-Z. And for the most part, he's made that song 100 times before and after U Don't Know.
OP is talking about Jay-Z's worldview. It's not expansive like your best hip hop artists. Jay-Z's worldview is Jay-Z. Lettuce be reality. That doesn't make Jay-Z wack, and he's still one of the greatest to ever do it, but GOAT? How can you be GOAT when the greatest rappers have expansive worldviews? Frankly, we crown rappers GOAT because they're the most observant about shyt we hadn't thought about/needed to know.
Ghost is not a good example. Look at his verse on "I Cant Go To Sleep" and how that shyt starts.
Technique is ill son, watch how I spill one
Peace to Biggie, 2Pac, Big L and Big Pun
Havoc on the streets of Staten, snitches
House nikkas, children watch as they produce the same pattern
Somebody raped our women, murdered our babies
Hit us with the cracks and guns in the early 80's
For those that murdered me shall stand before God
To fall at the hands of fate, then out comes the rod
Bring it back, bring it back, bring it back
What the fukk is going on, I can't go to sleep
Feds jumping out their jeeps, I can't go to sleep
Babies with flies on they cheeks, it's hard to go to sleep
Ish bowled two 6's twice, I couldn't go to sleep
Aiyyo we deep in the stairs, we carry big guns
Whippy got hit up with the big shyt, bong bong
Yes, Ghost is speaking in first person as an observant first-person, but the reason this hits so hard is that Ghost is speaking on larger issues/things than just himself.
Yup. Another good example of range Ghost possesses that Jay Z doesn't would be Impossible...
Call an ambulance, Jamie been shot, word to Kemit
Don't go Son, nikka you my motherfukkin heart
Stay still Son, don't move, just think about Keeba
She'll be three in January, your young God needs you
The ambulance is taking too long
Everybody get the fukk back, excuse me bytch, gimme your jack
One, seven one eight, nine one one, low battery, damn
Blood comin out his mouth, he bleedin badly
Nahhh Jamie, don't start that shyt
Keep your head up, if you escape hell we gettin fukked up
When we was eight, we went to Bat Day to see the Yanks
In Sixty-Nine, his father and mines, they robbed banks
He pointed to the charm on his neck
With his last bit of energy left, told me rock it with respect
I opened it, seen the God holdin his kids
Photogenic, tears just burst out my wig
Plus he dropped one, oh shyt, here come his Old Earth
With no shoes on, screamin holdin her breasts with a gown on
She fell and then lightly touched his jaw, kissed him
Rubbed his hair, turned around the ambulance was there
Plus the blue coats, Officer Lough, took it as a joke
Weeks ago he strip-searched the God and gave him back his coke
bytches yellin, Beenie Man swung on Helen
In the back of a cop car, dirty Tasha tellin
But suddenly a chill came through it was weird
Felt like my man, was cast out my heaven now we share
Laid on the stretcher, blood on his Wally's like ketchup
Deep like the full assassination with a sketch of it
It can't be, from Yohoo to Lee's
Second grade humped the teachers, about to leave
Finally this closed chapter, comes to an end
He was announced, pronounced dead, y'all, at twelve ten
