I didn't know it wasn't on there, but mobb sampled scarface twice. once on 'it's mine' w/ nas and on 'g.o.d. pt. III' off of i think that hell on earth album. rick ross used 'push it to the limit' and i'm pretty sure it was cam'ron who sampled 'rush rush.' Ever heard of this cd, 'Music Inspired by Scarface,' all rap stuff. http://en.wikipedia.org/wiki/Music_Inspired_by_Scarface
and i think everyone's sampled that, "warriors, come out and play," thing. i like hearin old movies and stuff get sampled though.
