(Chris DeStefano, Brett James, Priscilla Renea) The raucous "Somethin' Bad" turned into something great, thanks in part to a 19th century hymn. In 2011, Underwood, joined by Vince Gill on guitar, belted out a goosebump-raising rendition of "How Great Thou Art" for the ACM's Girls Night Out: Superstar Women of Country TV special. Seated in the audience, Lambert was inspired to propose working with Underwood on a track for her next album, Platinum. "'Somethin' Bad' came across and it just felt like the rock & roll edge that she and I have in some of our songs put it all into perspective," Lambert told Rolling Stone Country. "I sent it to her and she said yes. It was that easy." Get ready to clear some awards-shelf space, ladies.
