Jay ghostwrote a lot for Bleek. Man where do you think all the Bleek and Nas shit came from, Jay ghostwrote for Bleek on his first album and snuck Nas disses in there (that is some slick ass shit if I may say so myself, subliminal dissing while ghostwriting smh). Bleek had to go in on that though whether it was his shit or not. Beans was fresh off the block back then and he was tearing shit up.
