26. The Lumineers, 'Ho Hey'
This song introduced America's answer to Mumford & Sons, complete with roots-rock barn-stomp, chain-gang choir and lyrics about hanging around Chinatown, waiting for a girl. Colorado kid Wesley Schultz sings, "I don't know where I belong. . . ./I know I can write a song" like a heart-on-sleeve high-plains drifter.
