21. Carrie Underwood
Winner of the fourth season of American Idol back in 2005, Carrie Underwood was catapulted into the public eyes as the newest star in the music industry. Over the years she’s become a phenomenal actress, songwriter, and country singer. She brings religion into her country songs, as most do, with one of her most famous songs named “Jesus, Take the Wheel.” To date, she is the first and only country artist to have all first five of her studio albums reach either one or two on the Billboard 200.
