Mr. Know It All (3:52)

According to the Mr Know It All Songfacts, the song was debuted on August 30, 2011 during a live webcast hosted by Clarkson on her official website. During her Livestream chat Clarkson discussed why the song was chosen as the album’s lead single. “We picked ‘Mr. Know It All’ because it was unlike any song that, really, I’ve ever come out with,” she said. “Secondly, just because it’s very different from a first single for me. Usually we go with an anthem, guitar-driven song. This is very different, and I was really into it… It’s just super sassy and it sets up the album nicely. The whole theme is very empowering.”
