As we all know, J. Cole is dropping his Cole World: The Sideline Story on September 27th and he let go of one of the most hyped up tracks on the project, featuring Jay-Z, today.  Only the clean version for now but it is too dope not to listen to. Download after the jump. Oh yeah, the production is also by the multi-talented Cole, figured you all might want to know that. DOWNLOAD: J. Cole - Mr. Nice Watch (feat. Jay-Z) UPDATE: J.
