Carrie Underwood was a teenage metalhead. Hair metal, that is. Growing up in small-town Oklahoma, the future country titan developed a love for singers like Sebastian Bach and Axl Rose, whose elastic voices left a permanent impression. "It was people like [Rose] who taught me how to sing," she said last year, tipping her hat to an artist whose songs she's been covering since 2006. Here, we round up 11 of Underwood's best Eighties covers, from Mötley Crüe's "Home Sweet Home" and INXS' "Never Tear Us Apart" to nearly half of Guns N' Roses' greatest hits.
