This song is definitely a pop song. It has a catchy chorus, a distinct beat and her voice is definitely in pop mode. I love it.
In her preview of the song on Good Morning America Taylor said, "The song we're releasing tonight ... it's a song that's one of my favorite songs on the album because it sounds just as chaotic as the feeling was when I wrote it. It's a song about kind of being frustrated with yourself because you have your heart broken and you knew when you first saw that person you saw all these red flags and you just went for it anyway, 'So, shame on me.' "
Who is this song about? I had my suspicions when I first heard the song, but after watching the music video I definitely know who it is. It is about John Mayer!
Here are some of the clues from the lyrics. The first is, "Once upon a time, a few mistakes ago". There are some rumblings that this is about Harry Styles, it is not, why not? This line. John Mayer was definitely a few mistakes ago.
She says that this guy "never loved me or her or anyone or anything." And that as soon as she "fell hard" he "took a step back." How many women has John Mayer tried to get just so he could dump them? Taylor definitely knew he was "trouble when you walked in" and in the end "heard you moved on from whispers on the street" and she knew she was just "a new notch in your belt." She sings about not really knowing the status of their relationship, just wanting to talk to him again when she saw him CMT awards in the song "The Story of Us". John Mayer clearly never gave any closure to Taylor, boo John Mayer.
The other clues come from the music video. The guy in the music video has a lot of tattoos as does John Mayer. The guy in the music video plays the guitar and is a musician, John Mayer certainly is that. The other may come from the necklace that is featured prominently in the video. It seems to be one that is half of another necklace, and it appears that the guy in the video is wearing the other half at times. He gives this necklace to her and is seen wearing it. In the end she drops it on the ground to signify the end of their relationship. Taylor and John sang "Half of My Heart" together for John's album "Continuum". Taylor is also seen wearing a leather jacket, much like one that John Mayer wore while they were dating.
What is most important about this song though is Taylor communicating her feelings about how she lost herself in the whole relationship. In the music video she has a voice narration introduction, she says "I think that the worst part of it all wasn't losing him, it was losing me". She knew "his world moved too fast and burned too bright" but wondered how "the devil be pulling me towards someone who looks so much like and angel when he smiles at you?" The video focuses on Taylor's confusion and loss of herself. She wakes up in the ruins of a party, very disheveled. The mood of the video is very melancholy and bleak, void of bright and vibrant colors. At the end of the video she says, "I don't know if you know who you are until you lose who you are". Taylor has definitely moved on, is happy and dating again, and I am happy for her, because John Mayer definitely was trouble.
