T-Pain mixes a beer-and-ice cream cocktail

The Grammy-winning performer T-Pain has made big hits, like "Bartender" and "Blame It (On The Alcohol)." But he's best known for helping to popularize a vocal processing technology called Auto-Tune.  "It turned into a full genre of music," he said. "It's everywhere. It's in cartoons, commercials. It's everywhere."

Some people hated the effect. But for T-Pain, who was born Faheem Rasheed Najm in northern Florida, Auto-Tune meant freedom.

"I've always wanted to sing from the beginning. But in Tallahassee, you were seen as soft, or you were seen as not a man."
