Call the kings of '80s hair bands carpetbaggers, but Jon Bon Jovi spent 17 years writing with Nashville tunesmiths before recording part of 2007's 'Lost Highway' there. Sugarland's Jennifer Nettles helped Bon Jovi become the first rock band to have a No. 1 country single when she sang 'Who Says You Can't Go Home' with them. The New Jersey rockers have also duetted with LeAnn Rimes and the late Chris LeDoux.
