Every single weekday, Kelly Clarkson opens her daytime talk show by covering someone else’s song. Given the sheer volume of other people’s music that this task requires, the whole project has led Clarkson into some unexpected places. A couple of weeks ago, Clarkson covered the classic Radiohead album track “Exit Music (For A Film).” Today, Clarkson has gone into the ’80s college-radio zone, and she has taken on the Smiths.
