Rascal Flatts return to familiar territory this week, for the 13th time, to be exact. The hot country trio find themselves at the top of the Mediabase/Country Aircheck country singles chart with their latest hit, 'I Won't Let Go,' marking their second consecutive chart-topper.

The new No. 1 for Flatts' Gary LeVox, Jay DeMarcus and Joe Don Rooney, is their 13th chart-topping single since launching their red-hot career 11 years ago.

The inspiring power-ballad was written by Steve Robson and Jason Sellers, who just came off a three-week No. 1 as a co-writer of the Jason Aldean and Kelly Clarkson blockbuster hit, 'Don't You Wanna Stay.'

Flatts fans can catch the trio performing the No. 1 hit today on the 'Oprah Winfrey Show,' as the show-closing song for the third-to-last episode in the talk-show host's 25-year show history. The guys’ performance became a special dedication to Winfrey from her staff and producers and was filmed last week in Chicago as part of a who’s who of Hollywood cast.

Rascal Flatts are gearing up to hit the road this summer during their Flatts Fest tour, featuring Justin Moore, Sara Evans and Easton Corbin, which kicks off June 18 in Bristow, Va. For a complete list of dates for where the tour will be stopping, click here.
