The video below shows Swift belting out her smash hit at the Grammy Museum on Sept. 30. Swift's exhibit, The Taylor Swift Experience, ran from December 13, 2014 to October 4, 2015 at the museum and the singer closed it out with this performance.
"I'm going to play you a song that I wrote about a relationship that I was in that the number one feeling I felt in the whole relationship was anxiety," Swift said at the Grammy Museum.
"Because it felt very fragile, it felt very tentative. And it always felt like 'OK, what's the next road block? What's the next thing that's gonna deter this? How long do we have before this just turns into an awful mess and we break up?'"
Take, it away Taylor!
And, of course, happy birthday "1989!"
