T-Pain's fingerprints are all over pop and R&B and hip-hop. He wasn't the first musician to use Auto-Tune as an instrument - he noticed it on a Jennifer Lopez remix, and remembers "Deep" well - but it was, as he says, his style. For a while, in the mid-2000s, he lived at the top of the charts. Check out the 29-year-old singer belting out hits such as "Buy U A Drank, "Up Down," and "Drankin' Patna" in the video below – all without the Auto-Tune we've come to associate anything T-Pain related with. Enjoy!
