You say the reason for puttin Cash Money on the bottom like someone is going to disagree or something....in a lot of ppl's eye they don't even deserve to be up there at all (and yes these are southerners who feel that way).
I'm new skool so I'll go with:
Luda, Tip, Jeezy, Outkast and Scarface.
I wanna acknowledge UGK 8-Ball n MJG as southern legends like Outkast are.
The ppl on my list are genuine to southern rap...you won't see them crossing over with nothing but HIP-HOP! (Outkast gets a pass cus 3 stacks did that Love Below album)
