Kelly Clarkson fans say her ‘voice is made for metal’ after listening to her Metallica cover
Kelly Clarkson is a heavy-metal goddess. Clarkson, whose ability to sing a wide range of genres ( classics, rock anthems and even theme songs, among them) dates all the way back to her "American Idol" days, once again reminded fans of that ability when she covered Metallica’s “Sad But True” during the “Kellyoke” portion of her talk show May 6.
