49. Matt and Kim, 'Cameras'
The world’s most adorable dance-punk duo delivered a worthy follow-up to their breakthrough hit “Daylight” with this off-kilter stomper, which features the year’s most infectious synth-horn line and a timely chorus to which the smartphone-addicted masses should take heed: “No time for cameras, we’ll use our eyes instead.” Good idea, Matt and Kim! But we’re still snapping a few pics of Kim crowd-surfing at your next show. That girl is photogenic.
