On last night's battle round episode (April 15) of Season 4 of 'The Voice,' two belters closed out the show with an epic vocal bout. Team Adam Levine sent Judith Hill, a former backup singer for Michael Jackson, up to the mic to go vox to vox with Karina Iglesias. They tore through 'It's a Man's, Man's, Man's World.' While it may be a dude's world, at least according to those lyrics, these alpha female divas owned it, bringing the coaches to their feet. It was more like a woman's world. So how did A. Lev choose?

Well, it was not easy. He listened to the critiques of his fellow coaches, like Blake Shelton, who felt that Iglesias "brought it," and applauded her for not backing down against someone as experienced as Hill. He called Adam stupid for putting them together and forcing a choice to be made.

Usher Raymond said the women shook the entire room with their voices. It was ironic that so much female vocal power sang lyrics about it being a man's world.

We love that they bowed to one another before they began singing. It was very 'Art of Wa.'

Karina surprised us all, since we already knew that Judith was a pro. She sang with Michael Jackson for goodness sake!

Levine ultimately chose Judith, but we all knew that the coaches were going to try and steal Karina. And that's just what Shakira did. The Latina dynamo said that not turning her chair for Karina during the blind auds haunted her. So she rectified it.
