The Voice
NBC, 8:00 p.m. ET
No more chair-swiveling and button-smacking. The audition rounds are over, the teams are selected, and now it's time for phase two of this series, the battle round. That's where two contestants from the same team square off against one another, after getting advice from their team's judge, and from guest mentors. This season, Blake Shelton's guest mentors include Kelly Clarkson, the first, very successful winner of American Idol -- whose appearance here must have the Idol producers saying, "Et tu, Kelly?" But her defection is timely and smart, as well as another sign of her already established career independence.
