Last week, Darius Rucker paused work on his third country album to throw a party in Nashville for the Charleston, SC 1966 No. 1 single "This," co-written with Frank Rogers and former American Idol judge Kara DioGuardi. "'This' was the first song I ever wrote on iChat," says Rucker. "Kara was in Los Angeles and Frank and I were in Nashville. I just thought it was the perfect song to really bridge the gap from Learn To Live to this album."
