Listen: Taylor Swift releases ‘Shake It Off,’ from new album ‘1989’

“It’s finally time to tell some secrets,� Taylor Swift wrote Monday on Twitter. Then she took to the talk-show-like confines of a live stream and began telling them.

The big takeaway: Swift has completed a new album, her follow-up to 2012’s characteristically blockbusting “Red.� The record is called “1989,� which was the year she was born. It comes out Oct. 27.

And, perhaps most important, there’s a single, which you can hear this very instant.

Co-written and co-produced by the singer with Max Martin and Shellback (the same team behind her hit “We Are Never Ever Getting Back Together�), “Shake It Off� is an uptempo pop song in which Swift assures the haters and the heartbreakers that they’re no match for her.

“I keep cruising / Can’t stop, won’t stop moving,� she sings over percussive horn jabs, “It’s like I got this music in my mind saying it’s gonna be all right.�

Swift also released a music video Monday for “Shake It Off.�

Directed by Mark Romanek, it has the singer playing several roles, including a ballerina, a Lady Gaga lookalike and a woman wearing Skrillex-style eyeglasses.

There’s also a scene, one sure to generate controversy, in which Swift crawls beneath the legs of several dancers twerking in formation.

In a statement, Swift called “1989� her first “official pop album� and said she’d been inspired by the music of the late ‘80s, which she called “a time of limitless possibilities.�
