Bet you didn't see this coming! Saigon actually went on the radio and explained that he originally wanted T-Pain for this record. But Pain was charging 85K just for the hook and Sai Giddy wasn't feeling that, so he deaded Pain and let Just Blaze croon the hook with Auto-Tune. And you know what? It worked out pretty well since
it was a huge hit and Saigon's career really took off Just Blaze didn't sound so bad.
