 After the failure of the song (Clarkson's least successful single in the U.S. to date), sales of the "My December" album in the U.S. largely ceased, and no further U.S. singles from the album were released.However, in an interview with Nashville radio station 107.5 The River, Clarkson said that she released "Sober" so early because she wanted to show the diversity of music in "My December".In July 2007, "Sober" was a highlight of Clarkson's five-song set at Live Earth at Giants Stadium, with the audience audibly applauding her vocal line during the song's climax near the end.
