What kind of rap instrumental category does Gucci Mane use?

Dirty South, East coast, what? It's not crunk because it has more hihats and other things.

thanks!

bamboom, that's what I'm annoyed with. There doesn't seem to be a real category for his style of instrumentals

His beats really aren't categorized, they're just very simplistic and catchy.

dirty south

they can be categorized as mainstream, commercial, and pop, but the main category would be considered dirty south
