Tip wasn't removed because his verse wasn't good enough, but because Meth & Red complimented the grimyness of the song. Apparantly the idea for the song was concocted by D and Tip, but D's then manager argued for the rappers to be more commercial. Meth & Red were hot at the time, so they went with them.

As far as I know, the Q Tip version is yet to leak. I would love to hear it tho!

Peace
