Memory and Music as Emotional Time Capsules in Rewind It Back

Thematic Claim: Music as an Archive of Love

In Rewind It Back, music operates as a concrete record of emotional history. Hallie Hart’s childhood habit of pairing songs with important moments creates a personal soundtrack that preserves the texture of her relationship with Rio DeLuca. The novel argues that love can be physically stored—in mixtapes, playlists, and the act of listening—and that replaying those sounds can revive feelings that time and distance have tried to erode.

The Origin of the Tradition

The mixtape practice begins on Hallie’s thirteenth birthday. As shown in Chapter 7, she makes a cassette titled “Thirteen” with thirteen songs, each tied to a memory from the past year. When the older neighbour boy Rio asks to listen, he becomes the first person outside her family to share in her ritual. That night on the roof, he wears her handmade friendship bracelet and gives her his hoodie. The vulnerability of explaining why “Waterfalls” by TLC reminds her of a boy’s first crush, or why another track matters, forges an intimacy that outlasts their teenage years.

Hallie’s system—naming songs for stolen moments, failed hockey games, and quiet confessions—transforms fleeting experiences into landmarks. She tells Rio, “When I want to relive a moment, I can rewind it back and start from the beginning.” This line, recalled years later in chapter 43, becomes the novel’s emotional thesis.

Preservation Through Physical Objects

The most powerful evidence of music as memory appears in chapter 24, when Hallie discovers a black cardboard box in Rio’s closet. Every cassette and CD she made from ages eleven to nineteen is there, each case cracked from repeated use. The box also holds the tattered friendship bracelet she wove on her thirteenth birthday. Hallie had assumed Rio would have destroyed these artefacts after their painful breakup. Instead, he transported them cross-country, refusing to upgrade his old boombox because it was the only device that could play the tapes.

Rio’s explanation in chapter 29 crystallises the theme: “I didn’t have any other way to play the tapes and CDs, and not playing them wasn’t an option for me. For years, I’ve taken this fucking boombox everywhere with me. Held on to it, like if I could keep rewinding and replaying these moments we had, then maybe it wasn’t over.” The boombox, like the songs, is a bridge across lost time. He kept Hallie’s memories because they were also his own.

Recreating the Past on a New Birthday

The climax of the memory-music arc comes in chapter 43, another birthday—but this time Rio is the gift-giver. He has curated a modern playlist that mirrors Hallie’s old mixtapes, associating each song with a specific moment from their rekindled relationship. The first track is the one playing in the locker room before the game where he spotted her again. Later songs recall their first design meeting, the night she fell asleep in his car, the Moana soundtrack during babysitting, and the dance in the kitchen when they decided to try again.

The final song on his list is the one he was listening to when he signed his contract extension with the Chicago Raptors—a choice that keeps him in her city. By giving Hallie a new set of “important moment” songs, Rio reverses her original role, proving that love is not only remembered but continuously rebuilt. They listen on the same roof where they first sat as teenagers, now wearing wireless earbuds instead of a shared boombox. The technology changes, but the ritual remains.

Character Connections to the Theme

• Hallie Hart embodies the keeper of nostalgia. Her compulsion to label moments with music stems from a desire to freeze happiness. When she later stops playing music voluntarily (revealed in an earlier scene), it signals that pain has made her afraid to revisit memories. Her rediscovery of Rio’s box allows her to reclaim that part of herself.
• Rio DeLuca is the accidental archivist. He keeps the mixtapes not out of sentimentality, but because he cannot let go of the girl who made them. His preservation of the boombox and his refusal to throw away the broken cases show that he trusts physical objects to hold emotional truth. When he finally tells Hallie, “I want to rewind all of it,” he verbalises the theme for both of them.
• Supporting figures like Mia DeLuca and Indy witness and encourage this dynamic, reinforcing the novel’s found-family frame.

Symbolic Layers

• Boombox and Mixtapes: The boombox is a symbol of intentional memory. Rio keeps it long past obsolescence because it alone can play the cassettes. The mixtapes themselves are hand-labelled with Hallie’s “H-heart” signature—a mark of identity that Rio, in chapter 29, covers with his finger, as if to protect the imperfection.
• The Shared Roof: The roof between their houses is the stage for their first listening session and for the birthday playlist years later. It represents a space outside ordinary life where music and memory can meet.
• Rio’s Tattoo and Jersey Number 38: While not directly tied to music, these symbols anchor Rio’s identity in the physical; his jersey number and body art mark him as someone who wears his history.
• The Playlist Chapter: Chapter 2, a printed playlist of 22 songs, acts as a non-narrative overture. Tracks like “Second Chances” by Kiana Ledé and “Hold On” by H.E.R. prime the reader for the novel’s emotional register before any plot begins.

Complexity and Contradiction

The theme does not romanticise memory uncritically. Hallie discarded her own copies of the mixtapes “partly out of anger, and partly because I no longer recognized the hopeful girl who once saw the good in everything.” Her pain reveals that music can be a double-edged sword—it preserves love, but it also preserves hurt. Rio’s decade of replaying the tapes could be read as an inability to move on, a refusal to heal. The novel acknowledges this tension by having both characters admit their complicity in the breakup (chapter 29) before they can fully embrace the power of the songs again.

Additionally, the modern playlist in chapter 43 risks being a sentimental gesture, but Rio undercuts that by including real arguments and vulnerability. The final song about his contract extension shows that memory is not only about the past; it is also about choosing a future together.

Study Questions and Answers

1. How does Hallie’s method of tagging memories with songs create intimacy with Rio?
   Answer: By explaining why each song matters, Hallie lets Rio into her inner world. He becomes the first person to listen to the mixtapes with her, and that shared act of listening on her thirteenth birthday establishes a trust that survives their split.

2. Why does Rio keep the old boombox despite owning modern technology?
   Answer: The boombox is the only device that can play Hallie’s cassettes. Rio refuses to upgrade because “not playing them wasn’t an option.” The boombox physically ties him to the memories; replacing it would feel like abandoning the connection.

3. What does the condition of the mixtapes in Rio’s box reveal about his feelings?
   Answer: The cracked plastic, broken hinges, and worn edges show that he has played the tapes “endlessly over the years.” The physical damage contradicts Hallie’s assumption that he would have burned or shattered them. Instead, his care for the objects mirrors his care for her.

4. In what way does Rio’s birthday playlist in chapter 43 reverse the original dynamic?
   Answer: Hallie had always been the one compiling songs for special moments. By creating a playlist for their shared memories, Rio becomes the active rememberer, proving that he can also “rewind it back.” He uses modern earbuds to echo the boombox ritual, showing the tradition can evolve.

5. How does the novel address the potential pain of music-linked memories?
   Answer: Hallie stops playing music voluntarily after the breakup because it reminds her of what she lost. The novel validates that grief by showing her initial avoidance. Only when she sees that Rio kept the tapes does she begin to reclaim music as a source of hope rather than hurt.
