Gringo Suave is very "well known" where I am.
When I say "well known", that doesn't mean I could show up to any random place and mention "Gringo Suave" and expect people to be like "Oh him", but he's well known in radio land, especially RHYTHMIC and rhythmic top 40 sounds. The only thing though is I'm pretty sure that picking music for a rhythmic in Atl must be very different from how it's done in the west coast.
..As a matter of fact, it's probably different from the east coast as well! ;D
