Kelly Clarkson's new track "Mr. Know It All" hits internet

Kelly Clarkson dropped her new single, "Mr. Know It All," on her website this week. It's the first track off her 'Stronger' album, due in October.

The song is an obvious Clarkson song: straightforward, with a strong melody and a sing-along chorus. The midtempo breakup tune is about a girl letting her guy know that despite thinking he's got it all figured out, he doesn't.

The track was written by Brett James (who has a country pedigree, having written for Carrie Underwood), Ester Dean (Beyoncé, Usher) and Dante Jones. Brian Kennedy (Chris Brown, Rihanna, Backstreet Boys) also co-wrote and produced the track.

'Stronger' is Clarkson's fifth album release. It's the follow-up to 2009's All I Ever Wanted. You can pre-order the CD on amazon.com.
