Taylor Swift wasted no time in premiering a new song during her Yahoo livestream Monday night (Aug. 18).

As she danced and twirled around the studio, she mouthed along to her first new song, “Shake It Off,” off her upcoming new album 1989, due out Oct. 27.

“People can say whatever they want about us at any time and we cannot control that,” she told the audience about the lyrical content. “The only thing we can control is out reaction to it.”

“Shake It Off,” produced by Max Martin and ShellBack, continues Swift’s transformation into a pop star. The up-tempo, sunny tune recalls Pharrell’s “Happy” with its infectious claps and chorus. “I’m just gonna shake, shake, shake, shake, shake, shake it off, shake it off,” she sings over swelling horns.

The song marks a return to Swift’s partnership with Martin and ShellBack. The singer previously wrote “We Are Never Ever Getting Back Together” with the duo, among others.

“We decided to get back together,” she said, before admitting, “that was a terrible joke.”

Shortly after the premiere of the new song, Swift revealed the work that had gone into her new album and followup to Red. She said she went into the record, which was recorded over two years, “not wanting but needing to make a new style of music” that differed from her last output.

That record, 1989, is out Oct. 27. The cover features a picture of Swift taken by a Polaroid camera.

The livestream is the culmination of a few weeks of teases from Swift concerning, well, something. She began posting cryptic pictures and videos to her Instagram that eventually revealed the time, date and location of the Yahoo livestream via a video in an elevator, a picture of her cat and more.

The new song is Swift’s first since the new material off 2012’s Red, which still ranks as one of the top-selling albums of the last few years. It yielded four top 10 singles for the singer in her first major foray into pop from the country charts: “We Are Never Ever Getting Back Together,” “22,” “Red” and “I Knew You Were Trouble.”
