👀🎹🎬Taylor Swift walks across the stage and explains to the audience, “Now, I don’t know about you, but when I was really little… You know how you have your favourite song? That you would just play over and over again in your room, just blast it in your room, and you’d sing in front of your mirror – into a hairbrush right?”.
