Taylor appears to make direct references to the end of her relationship with Harry in "Is It Over Now?"—which she called a "sister" song to "Out of the Woods" and "I Wish You Would."

"Whеn you lost control / Red blood, white snow," she sings in the second verse, which ties back to an accident Taylor mentioned in "Out of the Woods." (Remember when you hit the brakes too soon? Twenty stitches in the hospital room.) 

"Blue dress on a boat," Taylor continues, a nod to a Jan. 2013 photo of her leaving a vacation with Harry after their rumored breakup. "Your new girl is my clone."

The Grammy winner also includes the bold lyric, "You search in every model's bed for somethin' greater, baby," in "Is It Over Now?" as an apparent reference to Harry's relationships that followed their breakup. (He's been linked to models Kendall Jenner, Nadine Leopold and Camille Rowe over the years.)

The lyrics also offer a connection to another beloved 1989 song, "Clean." In "Clean," Taylor details the aftermath of heartbreak and how she won't risk going back to a relationship after calling it quits with that person. "Ten months sober, I must admit," she sings on that track, "just because you're clean, don't mean you don't miss it."

In "Is It Over Now?," Taylor writes about a similar time period: "Let's fast forward to 300 takeout coffees later," which, if you had one coffee a day, would be nearly 10 months. So, as they say, the math is mathing.

1989 (Taylor's Version) is out now.
