The duo performed Destiny Child’s “Say My Name” and A Great Big World’s “Say Something” in Wednesday’s performance on the show — receiving universally positive feedback from the judges.

But the judge’s positive reactions weren’t the only good part.

On top of the move into the final round, the couple’s performance of “Say Something” was number one on iTunes.

“It was outstanding, it was beautiful, sincere, fantastic,” mentor and judge Simon Cowell said.

The winner of the X Factor will be named Dec. 19.
