Sauce Money is a legendary rapper from the 90s, and was a close friend of Jay Z during Jay's come up. In fact, they are from the same Marcy Housing Projects in New York, and he was around Jay Z when Jay was recording his first album, Reasonable Doubt.
While talking about those times in a new interview on VLAD TV, he was asked by VLAD how it is was watching Jay Z record rap verses without writing them down first, and he said...
"Well, I knew him when he was writing...he didn't have no choice not to write cos you couldn't read the sh*t that he was writing anyway. I would look at the pad and be like, yo, how do you even read this sh*t my n*gga. Like, this is crazy. But umm...then he started you know honing his craft, and then he stopped writing. You know, just doing it off the head. Yea."
