In the opening lines of "Drag Me Down," Harry Styles fiercely sings, 'I've got fire for a heart / I'm not scared of the dark / You've never seen it look so easy." Facing indignity and adversity, a special someone's love keeps the lads afloat: Perhaps their 26.1 million Twitter followers? The lyrical content of 'Drag Me Down" casts stalwart fans as key players in a real-time perseverance fable.

It doesn't hurt that the song itself has crossover appeal, hitting a sweet spot of pop and rock that listeners outside their Instagram demographic can access. If you compare NSYNC's final singles 'Pop" and 'Girlfriend," the One Direction hit reveals maturity and evolution their predecessors couldn't nail.
