Yeh i thort that when I first heard about it, but if you listen to Last Call (on college dropout) all the way to the end then Kanye talks about Jay just goin in when he was recordin and havin all his stuff done before Kanye even got there, and just doin one take or wateva, I think not writin is kinda believable for Jay-Z tho

Mmmm...
Maybe, Still Seams Hard To Believe Off Of ALL His Discs Not One Track Was Pre-Written...
THAT Is What Is Hard To Believe...

both of those niggas ill but im going with hov

jay-z is way better...nas is all lie's, and jay-z spits real shit
