I’m really enjoying this season of The Voice – partly because all four judges this year have found a way to interact playfully, and partly because the talent is markedly above this show’s norm. The singer they saved until last in the most recent installment, India Carney, knocked it out of the park with her rendition of Billy Joel’s “New York State of Mind,” leaving all four judges desperate to sign her. Christina Aguilera won that battle, because she was one of that contestant’s childhood idols – but this year, the competition among singers, and judges, should be especially fierce.
