It all went down on Good Morning America. Taylor played the song and revealed that it's one of her favorites on her new album 1989.
"I wanted to make sure that these songs sounded exactly the way that the emotions felt when I felt them. This song is about the fragility and kind of breakable nature of some relationships. This was a relationship where I was kind of living day to day, wondering where it was going, if it was going to go anywhere, if it was going to end the next day. It was a relationship where you kind of never feel like you're standing on solid ground," she said.
"That kind of a feeling brings on excitement but also extreme anxiety and kind of frantic feeling of wondering, endless questions. And this song sounds exactly like that frantic feeling of anxiety and questioning, but it stresses that even if a relationship is breakable and fragile and full of anxiety, it doesn't mean that it isn't worthwhile, exciting, beautiful and all the things that we look for."
Of course, Taylor didn't reveal WHO the song is about. There's tons of speculation, though. She sings about a snowmobile accident in it, and many fans are sure that situation went down with Harry.
