I just read it again in the liner notes and I got some of that part wrong. Here's how it goes (its even better now):

500 years befo' Iceberg ever leaned back in a 'lac/
Befo' they told Rosa "Black in the back"/
Befo' the CIA told Ricky Ross to put crack in a sack/
And Gil Scott traded rappin' for smack/
This beat alone should get platinum plagues/
I'd rather see a million of ecstatic to scrap/
Cuz if we bappin' 'em back/
We automatically stack...
