Chase McGill is a songwriter who defines the sound of modern country as much as anybody around, with all that entails. He turns out deeply soulful ballads like Kenny Chesney's "Don't It" or Little Big Town's slow-burning tearjerker "When Someone Stops Loving You." But McGill is also an ace at crafting hooky-as-hell party-starters like Kane Brown's randy, honky-tonking "Short Skirt Weather" and Luke Bryan's bigger-than-life beach-blanket anthem "Sunrise, Sunburn, Sunset."
