14. Brad Paisley, "Southern Comfort Zone"
Brad Paisley has always pushed country's boundaries — geographically, musically and ideologically. Without ever sounding condescending, he takes the listener around the globe on 2013's "Southern Comfort Zone," explaining, "I can't see this world unless I go outside my Southern comfort zone," and that there are wondrous adventures to be had in places that seem at first strange and unfamiliar. But, as he concludes, the nicest part of any trek is getting to come back to "my Tennessee home," even if he knows he's not going to be down on the farm for long before wanderlust sets in again. For the song's video, the country superstar visited eight countries in eight days, running into (literally) the Band Perry in Norway and jamming with a giraffe in Kenya.
