The Artist: Sean Kingston
The Mixtape: King of Kingz (2011)
Did It Live Up To The Gangsta Grillz Standard? Only because it allowed us to use "DJ Drama" and "Justin Bieber" in the same sentence. Biebs was featured on the final track on the 'tape, "Won't Stop." Which makes us think: When is Bieber gonna get his own Gangsta Grillz mixtape—and will it live up to the GG standard? Probably not, but we wouldn't be surprised if it dropped soon anyway.
