Nashville stars like Kenny and Carrie and Taylor may have first-name-only wattage, but Aldean's got numbers on his side, thanks to his monster 2010 album, My Kinda Party. Look for more ten-gallon hits on Night Train, including ''Wheels Rollin' '' and the title track. ''A lot of people call it sloppy playing,'' Aldean says of the guitar style made popular by the likes of Slash, his personal ax hero. ''I just call it cool.'' —Kyle Anderson
