Cant believe riff wrote this classic

I heard from a reputable source that RiFF RAFF wrote an album called The Gucciprint back in 2000. The rights to this album were purchased by an amateur named Jay-Z, renamed The Blueprint, and released in 2001.

Jay-Z conveniently 'forgot' to credit RiFF RAFF in the album's credits, and as a response, RiFF had planes fly into the World Trade Center on the album's release date. The distraction from this event harmed Hov's first day sales greatly, and to this day, it is known that Jay cannot leave New York without getting a pass from RiFF.
