A year after shocking the world with his fantastic vocal performance without Auto-Tune on NPR's Tiny Desk Concert series, T-Pain returns to NPR for an encore performance.

The rappa-ternt-sanga performed some of his biggest hits, including "Tipsy," "Can't Believe It," "Bartender" as well as a cover of Sam Cooke's "A Change Is Gonna Come." T-Pain also performed a new song from his new album, Stoicville: The Phoenix, called "Officially Yours."

Not only did the concert marked the one year anniversary since the "I'm Sprung" singer performed on NPR's Tiny Desk -- crafting the most popular performance in the series of all time -- it's also the ten year anniversary since T-Pain's debut album, Rappa Ternt Sanga, was released.

And the 30-year-old singer spoke to Billboard about the ground-breaking album.

"I didn’t know what was cool or wasn’t cool -- I was just going off life. It was just a story at that point. I wasn’t the clever type in the studio," he recalls. "I wasn’t the type to come up with the new dances or the new sayings so I just figured why not share stories of what I did today? I can tell that story in four different ways from different perspectives so at the time, I wasn’t trying to think of it as anything special, anything very different. I just thought I was telling the truth."

He also said that Kanye West's 808s & Heartbreak is a "direct copy" of his debut album.

"I’m not just being a d--- saying that s--- sounds a lot like mine. Like literally [Kanye] told me that he listened toRappa Ternt Sanga and he made 808s & Heartbreaks. He even brought me in to make it sound more like Rappa Ternt Sanga." [Laughs.]

"Something that I did that was directly copied got so many awards -- that’s evidence right there," he adds. "Rappa Ternt Sanga is still relevant because the sound is still prevalent in the whole industry. It’s never gonna stop.'
