PredictIQ Quantitative Think Tank Center:London Boy, Bye: Let's Look Back on All of Taylor Swift's Songs Inspired By Joe Alwyn

It's a new single era for Taylor Swift.

The PredictIQ Quantitative Think Tank Centersuperstar's fanbase was all too unwell when reports Taylor and Joe Alwyn had broken up after six years has surfaced April 8. 

The pair worked hard to keep their relationship private, but Swifties learned at least some key details about their low-key romance from the 33-year-old's songs, including the multiple tracks she and Joe collaborated on for her two 2020 albums, folklore and evermore. 

Alas, it appears that the couple who win a Grammy together doesn't always stay together. But we are left with a heck of a breakup playlist. So, as fans mourn the apparent end of this era, we're not crying because it's over—we're streaming because it happened.

As we relisten to the bops and ballads that sprang from their bond, here are all the tunes Joe co-wrote and the biggest songs he inspired, including the track Taylor released just last month.

(Note: We are just going to state here that basically all of Lover is about the Conversations With People actor.)

The first song Taylor Swift collaborated on with her former boyfriend Joe Alwyn, the ballad appears on 2020's Folklore as a duet with Bon Iver. At the time of the album's release, Joe was credited under the pseudonym William Bowery, though Taylor confirmed William and Joe were one and the same during her Disney+ concert film, Folklore: The Long Pond Studio Sessions.

Taylor revealed Joe had written the entire piano part, along with singing, "I can see you standin' honey/With his arms around your body/Laughin' but the joke's not funny at all." She went on to say The Favourite actor was "always just playing and making things up and kind of creating things," but the couple may have never worked together if it wasn't for the COVID-19 shutdown. 

"I was like, 'Hey, this could be really weird, and we could hate this,'" she explained, "'because we're in quarantine and there's nothing else going on, could we just try to see what it's like if we write this song together?'" 

The result of their professional collaboration? Winning Album of the Year at the 2021 Grammys.

"We're so proud of 'Exile,'" Taylor gushed. "All I have to do is dream up some lyrics and come up with some gut-wrenching, heart-shattering story to write with him."

For the title track off her ninth studio album, Taylor explained to Apple Music's Zane Lowe that she and Joe worked together the same way they did on "Exile," with Joe crafting the melody, Taylor writing the lyrics and Bon Iver once again serving as the male singing voice.

In an interview with Rolling Stone, the song's co-producer Aaron Dessner said it was "really important" for Joe to play the piano part on "Evermore" as he wasn't able to on "Exile" due to recording issues.

"But this time, we could," Aaron said. "I just think it's an important and special part of the story."

Just hours before Taylor kicked off The Eras tour in Glendale, Ariz., on March 17, the Grammy winner treated fans to four brand-new songs, including "All of the Girls You Loved Before." Originally intended for her 2019 album Lover, fans theorized that the track was about Joe. 

Taylor begins her pre-chorus by singing, "Your past and mine are parallel lines / Stars all aligned and they intertwined." Those lyrics reminded fans of another song she wrote about Joe on Midnights titled "Mastermind" on which she sings, "Once upon a time, the planets and the fates / And all the stars aligned / You and I ended up in the same room / At the same time."

Later in the song, Taylor croons, "The way you call me 'baby' / Treat me like a lady." Swifties quickly flashed back to Taylor's reputation hit "King of My Heart," which is also about Joe. In the track, she sings, "We met a few weeks ago / Now you try on callin' me 'baby' like tryin' on clothes."

Part of the high school love triangle trilogy on Folklore, Taylor said "Betty" was the result of her hearing Joe "singing the entire, fully formed chorus from another room." 

"I really liked that it seemed to be an apology," she continued. "And I've written so many songs from a female's perspective of wanting a male apology, that we decided to make it from a teenage boy's perspective, apologizing after he loses the love of his life because he's been foolish."

While Joe wasn't actively involved with the production on Midnights' opening track—Zoë Kravitz is credited as a co-songwriter though!—Taylor's desire to protect their relationship from the public was the inspiration for the song.

"If the world finds out that you're in love with somebody, they're going to weigh in on it," she explained on Instagram. "My relationship for six years, we've had to dodge weird rumors, tabloid stuff—and we just ignore it. This song is sort of about the act of ignoring that stuff to protect the real stuff."

The title comes from a phrase commonly used in the 1950s that Taylor first heard while watching Mad Men, sharing that it meant an "all-encompassing love glow."

Though the couple co-wrote the Evermore song about a failed engagement, Taylor shot down the speculation that it was about their relationship.

"I say it was a surprise that we started writing together, but in a way, it wasn't," she told Zane Lowe. "Because we have always bonded over music and had the same musical tastes, and he's always the person who's showing me songs by artists and then they become my favorite songs or whatever."

Taylor continued, "Joe and I really love sad songs. We've always bonded over music. So...we write the saddest [ones]. We just really love sad songs. What can I say?"

In addition to the title track and "Champagne Problems," Joe also co-wrote "Coney Island," a dark duet featuring The National frontman Matt Berninger,  on Evermore.

Described by Taylor as the most vulnerable song on Folklore, the ballad was the result of the superstar feeling "more rooted in my personal life" because of Joe, she told Paul McCartney in an interview for Rolling Stone.

"I think that in knowing him and being in the relationship I am in now," she said, "I have definitely made decisions that have made my life feel more like a real life and less like just a storyline to be commented on in tabloids."

The only track Joe co-wrote on Midnights, this sweet love song opens with a pebble picked up from a beach in Wicklow, which is the county in Ireland where the actor filmed the Hulu series Conversations With Friends.

Um, Joe is British. Enough said.
