The Chainsmokers parlayed scruffy looks and frat-bro yuks into a cushy seat atop pop's throne—a path their videos followed, too. Where early clips like "#Selfie" and "Split (Only U)" were interested in raving and raging, their perspective soon turned stylishly sensual ("Closer"), mind-bendingly conceptual ("Paris") and even probingly reflective ("Sick Boy"). No matter the mode, they dare you to look away.
