Kelly Clarkson’s fourth album thrillingly builds on the promise of her 2004 blockbuster “Since U Been Gone," pairing souped-up riffing with sugar-spun hooks and the inaugural American Idol’s acrobatic voice. Feisty sing-along choruses fuel the charging “My Life Would Suck Without You” and the no-nonsense “I Do Not Hook Up,” while “Already Gone” updates the power-ballad ideal with plush synths and Clarkson’s devastated vocal. This pop-rock triumph showcases Clarkson’s bottomless charm and undeniable voice.
