MOS DEF CHALLENGES JAY-Z

Mos Def feels some type of way about Jay being labeled as "The Best Rapper Alive". There's numerous great rappers that Jay hasn't battled so now Mos is givin him the opportunity to do so in New Orleans for a charity.
Mos Def, MF Doom, Nas, && Jay Electronica vs. Jay-z && whoever he chooses.
In my opinion, IF Jay-z actually takes him up on this... IF... then I'm puttin money on Mos & his 3. People know what Nas can do, but mos, doom && jay electronica are HIGHLY underrated.
