Taylor Swift Shake It Off: No More Heartbreaking Odes For Old Flames? First Song Off “Documented, Official Pop Album” Gets Mixed Reviews!

Taylor Swift's 'Shake It Off' music video came out during the country singer's livestream via Yahoo! last Monday. She also shook up the entire music industry by sharing details about her new album, '1989.'

Anticipation for the four-time Grammy winner's new album rose after her genre-bending album 'Red' churned out hits like 'We Are Never Ever Getting Back Together' and 'I Knew You Were Trouble' in 2012.

Fans have grown to love her confessional country songs about old flames and the singer's music grew more intense with her genre experiments in her last album.

For the first single off her first "documented, official pop album" however, the distinctive guitar strums usually found in the country princess' songs have completely been left out.

Billboard points out: "'Red' hits like "We Are Never Ever Getting Back Together" and "22" paired their fizzy melodies with slick guitar strums, but 'Shake It Off' disregards the instrument altogether, instead coiling its verses around a subtle saxophone line."

The New York Daily News also shares the same sentiment, noting that "Swift has been steadily erasing even the slightest hint of Nashville from her sound over the course of her four previous albums. 'Shake' completes the trend. It's pure Hollywood pop - glossy, brisk and aiming for fun."

HitFix and Hypebeast were more outright in their disappointment, calling Taylor Swift's 'Shake It Off,' the latter calling the new song "annoying" and even listed eight reasons why.

On the other hand, Billboard believes that Swift's new tune will be a "surefire hit."

"Few musical artists would dare to reinvent their sound so brazenly, especially with expectations so high," the review reads. "But with "Shake It Off," Swift proves why she belongs among pop's queen bees..."

Even Hypebeast, despite its depressed take on Swift's new genre, admits that Swift has always been "musically interesting."

Whether fans or critics will love her new sound or not, Swift believes she can just 'shake off' negativity.

"People can say whatever they want about us, at any time and we can't control that. The only thing we can control is our reaction to that," Swift says about her new song.

'1989' will hit music stands on October 27.
