"I'm T-Pain, you know me," T-Pain sings on one of his biggest hits, 'Buy You a Drank (Shawty Snappin')'. But do we really know the famed producer without auto-tune? Well, we do now -- and we're completely obsessed.

T-Pain -- a who sings the most addictive auto-tuned hooks on jams like Flo Rida's 'Low,' Chris Brown's 'Kiss Kiss,' Jamie Foxx's 'Blame It,' The Lonely Island's 'I'm on a Boat' and countless others -- gave an intimate performance of three of his hits on NPR's 'Tiny Desk Concert' series. And best of all? He blew us away, sans auto-tune.

"This is weird as hell for me," he joked before beginning his performance, which started off with a seriously killer version of 'Buy U A Drank.' With his buttery-smooth vocals, T-Pain manages to make the bar pick-up anthem sound like the most romantic song in the world. We're totally entranced.

Do yourself a favor and check out T-Pain's totally stripped down, slightly NSFW, non-auto-tuned performance in the video above -- and prepare to have your mind blown.
