    Kree Harrison

    Harrison is Nashville veteran who had a publishing deal and a record deal before she was ever on Idol, but neither quite panned out. She dominated the stage from the first time she performed during Season 12, however, and placed second. Her most recent song is "This Old Thing," released in the spring of 2016.

    Clarkson was the very first winner of American Idol, way back in its first season in 2002, and she has since become an international superstar. Although her success has been primarily rooted in pop, Clarkson has released a duet with Reba McEntire, and she's also recorded with Vince Gill, qualifying her for a spot on this list.
