"Royal Flush" is the perfect rap song -- clever, fun, and memorable. Interestingly enough, it's Dre who registers the longest verse on this Big Boi gem. No one's complaining though. How could we, when he's cranking out intoxicating rhymes like, "Crack and I have a lot in common. We both come up in the '80s and we keep that bass pumping." Big Boi and Raekwon also post some poignant lines of their own, but Dre's verse will stick to your memory even after "Royal Rush" has pumped out its last bass. Then you hit the repeat button.
