The Chainsmokers know their way around an earthshaking drop, but they treat dance music as a cloak for irresistible pop songs. The New York duo originally went viral with a parody of selfie culture (“#Selfie”) and a paean to Kanye (“Closer”)—set to fist-pumping productions that combine trap snap, house punch, tropical flourishes and melodic hooks that sink in deep. From the pool party to the festival to the drive home with friends, The Chainsmokers have the soundtrack to living large.
