The story has been around for years: legendary producer Just Blaze let Jay Z listen to the classic "Oh Boy" beat before anyone else, but it ultimately ended up in the hands of Cam'ron who decided to use it as his own track. "It's very simple: I had the beat - made it like three different ways... and I kept toying with different ways to do it," Just Blaze begins as he explains how it all went down. He then goes on to say he played it for Jay Z, who asked that he hold it for him to use in the future. "And Jay would do that all the time,  you know, 'hold this for me, hold that for me,' then forget about it. Like all artists do."

Cam'ron eventually got a hold of it and sent the unfinished demo to Angie Martinez at Hot 97, and the rest, as we all know, is history.  All he had to do "was wait one day," Just Blaze says, as it cost them to lose a significant yet undisclosed amount of publishing money. Listen above as he details all and reminisces over the Jay Z/Beanie Sigel reunion above.
