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.”
