Aretha Franklin released her cover of Adele’s hit “Rolling in the Deep” on her new album Aretha Franklin Sings The Great Diva Classics, and she performed the track live on the Late Show with David Letterman.

Aretha Franklin Auto-Tune In "Rolling In The Deep"?

Franklin’s cover of “Rolling in the Deep” is the first single off her new album. And, while the cover has been well received, some fans are calling foul, suspecting Franklin of using auto-tune.

Over the past decade, auto-tune has become a staple of any studio music, but in 2006 Franklin gave an interview in which she claimed never to have heard of auto-tune. “I’ve never even heard of that [auto-tune]. No, I come from the old school where you do it yourself,” Franklin said at the time.

That said, other fans are accusing Internet trolls of creating a fake ‘auto-tune’ controversy, standing by Franklin.
