Every once in a great while, a song emerges to capture an era, a scene, a way of life. Nirvana’s “Smells Like Teen Spirit” defined grunge music in Seattle in the 1990s; “Stayin’ Alive,” and the Saturday Night Fever soundtrack from the Bee Gees, crystallized disco in the ’70s.

Now, the self-centered, social network-centric Internet era has its own defining jam: It’s called “#SELFIE,” and, yes, the hashtag is part of the title. The song, from New York City DJ duo The Chainsmokers, perfectly encapsulates the Instagram-obsessed, nightclub-hopping, selfie-posing twentysomethings who take over large swaths of New York, Los Angeles and other lounge-friendly metropolises on Friday and Saturday nights.
