With the angsty anthem "Since U Been Gone," Kelly Clarkson [1] managed to win legions of fans — including folks who probably never expected to care about a song by an "American Idol" [1] champ. Now, she's got a new single called "Never Again," [2] which takes the girl-power bitterness up a notch. Just consider the first couplet: "I hope the ring you gave to her turns her finger green / I hope when you're in bed with her, you think of me."

Rock guitars and deep synth strings just enhance the mood, and as with "Since U Been Gone," the chorus full of pumping crescendos. I'm not sure it matches the energy of her bit hit, though; listen to it here [3] and tell me what you think.
