As Billboard's youngest-ever Woman of the Year prepares to release her fifth album, 1989, she finds herself, as always, in the glare of a blinding spotlight of expectation – but if you think that scares her, you haven't been paying attention. She calls 1989 her most sonically cohesive collection, and armed with first single, "Shake It Off," she's ready to blaze into the next phase of her still-young career, where she'll continue to dance like no one's watching, write like she stole our collective diary, and inevitably soar to ever-greater heights. All that's left to wonder is how many more lives she’ll lift in the process.
