  "prompt": "Genre: Contemporary Trap-Soul R&B; BPM: 143; Key: D minor; Rhythm: A laid-back, half-time trap groove with fast 16th-note hi-hats and a deep, syncopated 808 kick/bass pattern creating driving pocket syncopation.; Instruments: Programmed 808 sub, crisp trap snare, ticking hi-hats, distant reverb-washed e-piano, ethereal vocal chops.; Vocals: Female lead with a breathy, intimate delivery on verses and soaring, layered harmonies on choruses, featuring lush background vocal stacks. A pitched-down male-timbre vocal appears in the bridge.; Mood: The feeling of being the only two people awake in a city at 3 AM, streetlights blurring through a rain-streaked car window, making dangerous promises that feel true in the moment.; Highlight: The sudden textural shift in the bridge where the main beat recedes, replaced by a stark, pitched-down rhythmic vocal chant that resets the song's emotional focus.",
  "title": "Vacant Seat",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Prominent sub-bass below 80Hz. Wide stereo field from panned vocal pads and reverb tails. Lead elements centered and dry.)\n(Inst: Ethereal vocal ad-libs with heavy reverb/delay, filtered e-piano chords, subtle vinyl crackle.)\n(Vocal-Perf: Breathy, wordless, atmospheric vocal runs.)\n(Chords: Dm7 - Gm7 - Cmaj7 - Fmaj7)\n(Melody-Contour: Descending pentatonic runs, creating a wistful, searching feel.)\n(Melody-Rhythm: Free-flowing, not tied to a strict meter, weaving around the implied beat.)\nSomewhere between, hmm\nStill here, still here, yeah\n\n[verse]\n(Inst: 808 sub-bass enters, crisp snare on 2 & 4, fast 16th-note closed hi-hats, e-piano continues.)\n(Vocal-Perf: Conversational, rhythmic, close-mic'd, and intimate. Slight vocal fry on phrase endings.)\n(Chords: Dm7 - Gm7 - Cmaj7 - Fmaj7)\n(Melody-Contour: Mostly stepwise motion, narrow melodic range, staying close to the root note.)\n(Melody-Rhythm: Phrases start just after the beat, syncopated, mimicking natural speech patterns.)\nYour hoodie's folded on the chair I never touch\nThe fabric holds the shape of you, that's way too much\nI bought two coffees out of habit at the drive-through\nSat there watching one go cold, pretending I was fine, too\nOpened up your contact just to read the thread\nAll the voice notes still unplayed, the ones you said\nI keep the ringer on at night in case you dial\nKnowing you won't call, I rehearse your name, that childish\n\n[chorus]\n(Mix: Stereo image widens slightly. Vocal layers are added, creating a fuller sound.)\n(Inst: Full drum pattern continues, background vocal harmonies are introduced.)\n(Vocal-Perf: Shifts to a stronger, clearer tone. Main lead is doubled, harmonies are stacked.)\n(Chords: Am7 - Gm7 - Cmaj7 - Fmaj7)\n(Hook-DNA: Core motif \"vacant seat\", a descending 4-note phrase (D-C-A-G); rhythm lands on the downbeat then pushes off-beat; repeats twice and dissolves into the post-chorus breath; anchors on the minor tonic.)\n(Melody-Contour: Arch shape. Ascending leap of a minor 3rd on the hook, then descends back to the tonic.)\n(Melody-Rhythm: Phrases land squarely on the downbeat, more forceful and direct than the verse.)\n(Melody-Harmonic-Tension: Melody holds the 5th over the Gm7 chord on \"when I'm with you\", creating a brief, pleasing suspension before resolving down.)\nThe seat stays vacant, no one fills your space\nI pour the silence in and still I taste your face\nEvery room recalibrates around your ghost\nYou took the center, left me with the coast\nThe seat stays vacant, floor still knows your weight\nI keep the deadbolt off like you might show up late\nSomething in the walls still holds your frequency\nNobody echoes through me like you did to me\n\n[verse 2]\n(Inst: Same as Verse 1.)\n(Vocal-Perf: Similar delivery to Verse 1, but with more attitude and clipped phrasing.)\n(Chords: Dm7 - Gm7 - Cmaj7 - Fmaj7)\n(Melody-Contour: Still narrow range, but with small, quick melodic jumps for emphasis.)\n(Melody-Rhythm: Maintains the syncopated, off-the-beat phrasing.)\nI rearranged the whole apartment twice (Yeah, twice)\nMoved every piece of furniture, same price (Same price)\nYour absence got a blueprint, fills the room (The room)\nSomething always gives you back to me too soon\nFound a birthday card I never sent — your name\nHandwriting looked like someone else's, still the same\nDeleted then undeleted, then deleted it\nGot a memory that won't let me forget a bit\n\n[bridge]\n(Mix: Beat becomes more sparse. Bassline drops out intermittently. Pitched-down vocal is centered but distant.)\n(Inst: Hi-hats and snare are filtered or removed, leaving kick and ambient pads.)\n(Vocal-Perf: A new, pitched-down male-timbre vocal enters with a rhythmic, chant-like delivery. Main female vocal ad-libs around it.)\n(Chords: Dm vamp)\n(Melody-Harmonic-Tension: Pitched-down vocal creates rhythmic tension against the sparse beat. Monotonous melody on root and 5th refuses to resolve, building anticipation for the final chorus.)\nVacant seat\nWhy I'm saving it, preserving something incomplete?\nVacant seat\nWhy I'm saving it, when leaving was your whole receipts?\nVacant seat\nWhy I'm saving it, you never even asked to keep?\nVacant seat\nWhy I'm saving it, and losing all my sleep?\n\n[chorus]\n(Mix: Most dynamic and widest section. Ad-lib tracks from the bridge continue, filling the space.)\n(Inst: Full beat returns with more energy. Additional background vocal layers added for emphasis.)\n(Vocal-Perf: Most passionate delivery. Lead vocal has more power, and ad-libs are more frequent and complex.)\n(Chords: Am7 - Gm7 - Cmaj7 - Fmaj7)\n(Hook-DNA: Core motif \"vacant seat\", descending 4-note phrase (D-C-A-G); rhythm lands on the downbeat then pushes off-beat; repeats twice and dissolves into the final breath; anchors on the minor tonic.)\n(Melody-Contour: Arch shape, same as the first chorus but with higher-register ad-libs floating on top.)\n(Melody-Rhythm: On-the-beat phrasing, driving the energy home.)\n(Melody-Harmonic-Tension: Melody again holds the 5th over the Gm7 chord, but added layers of ad-libs create more complex harmonic color around this tension point.)\nThe seat stays vacant, no one fills your space (Your space, your space)\nI pour the silence in and still I taste your face (Your face)\nEvery room recalibrates around your ghost\nYou took the center, left me with the coast\nThe seat stays vacant, floor still knows your weight (Your weight)\nI keep the deadbolt off like you might show up late (Show up)\nSomething in the walls still holds your frequency\nNobody echoes through me like you did to me, to me\n\n[outro]\n(Inst: Beat breaks down, leaving only the filtered e-piano and atmospheric vocal pads.)\n(Vocal-Perf: Returns to the breathy, wordless ad-libs from the intro, fading out.)\n(Chords: Dm7 - Gm7 - Cmaj7 - Fmaj7)\n(Melody-Contour: Descending pentatonic runs, fading into reverb.)\n(Transition: Final vinyl crackle and a long reverb tail into silence.)\nStill saved, still saved\nVacant, vacant, oh\nNowhere left to go, yeah",
