Awesome Music pages are Spoilers Off. You Have Been Warned.
- "Across the Spider-Verse (Intro)",
the opening track's first measures during the production logos at the very beginning, start off in the same key as the opening track in the previous film, but quickly become more urgent to warn the audience what they're about to see will be Darker and Edgier than the light-hearted events of ItSV. - Spider-Gwen's theme forms the backbone of the Action Prologue and is reprised in/incorporated into many subsequent tracks. Beginning with a slow, melancholy, lo-fi/ambient synthline reflecting Gwen's inner conflicts, it establishes the Spider-Gwen motif - a trilling synthesised guitar riff - as a call to action when her father is summoned to deal with a Vulture at the Guggenheim, then follows through with a pounding synth-rock anthem that reflects her poise and dexterity under fire. What makes Gwen's theme even better, as one Youtuber found out, is that the guitar riff occasionally heard in her theme is actually the original 1967 Spider-Man theme song sped up.
- Spider-Man 2099 gets his own theme which is part Mythology Gag, as it's based off of a portion of his theme from Spider-Man: Shattered Dimensions.
- "Spider-Man India (Pavitr Prabhakar)", which serves as Pavitr's theme, blends traditional Indian music with an electronic beat and is infectiously catchy as a result.
- As with the Prowler in the first film, the Spot gets his own unique theme. It escalates over the course of the film and the Spot becoming a multiversal threat, culminating in Spot Holes 2.
- "On the Run" by Cerebral Ballzy acts as Hobie Brown aka Spider-Punk's introduction, reflecting his afropunk, anarchic influences. Fun fact: Honor Titus, who is the lead vocalist of Cerebral Ballzy, is the son of Andres "Dres" Titus of hip hop duo Black Sheep, whose song "The Choice Is Yours" was prominently sampled in the grafitti mixtape scene from the previous movie.
- "Mona Lisa" by Dominic Fike, a catchy and upbeat love song that plays when Miles and Gwen swing through Brooklyn together after reuniting. It also helps to enhance the Ship Tease between them.
- "REALiZE" by LiSA of Sword Art Online and Demon Slayer: Kimetsu no Yaiba fame is no slouch either and is the official theme of the movie's Japanese dub.
- The hectic chase near the climax is scored by the blaring synths of "Light The City Up" by Cut The Lights, a pulsing and powerful rap track.
- "Nueva York Train Chase" is a nearly six-minute long, electronic ballad that perfectly suits the climactic battle between Miles and Spider-Man 2099, going from droning snyths for the fight itself, to a more dark and somber tone during the reveal that Miles is an Anomaly and that Peter B. and Gwen knew the entire time, and ending with a triumphant (albeit bittersweet) reprise of Miles' theme.
- "Across the Spider-Verse (Start a Band)" plays over the movie's final minutes, going from eerie and haunting as Miles is captured by Earth-42 Prowler, who reveals himself to be Earth-42's version of Miles, adding urgent beats as an empowered Spot returns to Earth-1610 ready to wreak havoc which could kill Jefferson Morales and the Spider Society, as well as destabilize all of reality, before transitioning to an energetic, triumphant rock piece as Gwen assembles her "new band" of Spiders from both movies to travel across the Spider-Verse to find Miles and Miles prepares a bioelectric blast, ready to face off against his evil counterpart, with its last few rock chords playing over the film's "To Be Continued" to create an unforgettably powerful ending to this film. Furthermore, it echoes the opening track, "Across the Spider-Verse (Intro)", which initially builds to a similar climax, but falls apart at the end as Gwen's drum motif becomes more intense and frenetic to the point that it dominates the rest of the music (which is reflected in-universe as Gwen wildly playing the drums while ignoring the rest of her bandmates, showing her inability to work with or bond with them). When the same theme is played at the very end, the drums work in perfect synchronicity with other instruments, reflecting how Gwen is now opening up to others and assembling a band of her own.
- The beautiful yet haunting end credits music, "Am I Dreaming" by Metro Boomin, A$AP Rocky, and Roisee, seems to reflect Miles' current thoughts, feelings and willpower after escaping the Spider-Verse Society Headquarters to get back home and save his father, only to find himself stranded in another dimension. He may have a heavy toll on his mental state after everything he's been through and feels beaten, but he can't and won't give up.
