"Eternal Sunshine" is directly tied to the film's tragic love story.
Grande described "Eternal Sunshine" as a "concept album" that was partially inspired by "Eternal Sunshine of the Spotless Mind," a 2004 sci-fi drama directed by Michel Gondry.
Grande is a noted fan of Jim Carrey, who plays the protagonist, Joel. The film follows Joel as he goes through a medical process to erase all memories of his ex-girlfriend Clementine, played by Kate Winslet.
Grande mimics this process in the music video for "We Can't Be Friends (Wait for Your Love)," in which she plays a character called Peaches. But in terms of lyrics, the album's title track is most closely related to the movie.
"So I try to wipe my mind / Just so I feel less insane / Rather feel painless," Grande sings in the second verse, a direct reference to the movie's premise.
Another lyric, "Get me out of this loop," is probably a nod to the movie's finale, when Joel and Clementine re-meet after having their memories erased. They decide to try dating again, despite knowing they already did — and would eventually grow to resent each other.
The final scene shows the same clip of Joel and Clementine running through snow, repeating over and over again. The glitchy loop implies a tragic fate for the lovers, who can't break free from their romantic impulses.
Grande has been open about her own personal patterns. In "Positions," the lead single of her 2020 album of the same name, she sings, "Heaven sent you to me / I'm just hoping I don't repeat history."
Another possible nod to "Positions" appears in the chorus: "I showed you all my demons, all my lies / Yet you played me like Atari," Grande sings, a reference to the company that made classic games like Tetris, Space Invaders, and more. The lyric is followed by a vintage video game sound effect.
In "Six Thirty," placed at track six on "Positions," Grande begs for reassurance from her then-partner: "What you gonna do when I'm bored / And I wanna play video games at 2 a.m.? / What if I need a friend? Will you ride 'til the end?"
The Atari lyric also ties back into the "Eternal Sunshine" theme: memory erasure is similar to restarting a video game; the illusion of a fresh start.
