  "prompt": "Genre: Alternative R&B with ambient pop and lo-fi hip-hop influences; BPM: 75; Key: F Major (with modal ambiguity); Rhythm: Slow, behind-the-beat trap groove with a deep, syncopated kick and skittering 16th-note hi-hats creating a laid-back but driving pocket syncopation.; Instruments: Washed-out Rhodes piano; close-mic'd felt hammers, hazy reverb. Deep 808 sub-kick; dry snap snare; skittering 16th hats. Subtle sine-wave sub; doubles piano root. Ambient, airy synth pads; slow attack/release. Pitched-up vocal chops; used as texture.; Vocals: Male tenor, shifting between relaxed singing and conversational rap-singing. intimate close-mic delivery with subtle, effect-driven pitch correction and occasional lush background vocal stacks.; Highlight: The abrupt transition where the main intimate vocal cuts out, replaced by a high-pitched, processed vocal melody that re-contextualizes the entire track's harmonic feel, creating a brain-scratching melodic hook.",
  "title": "Shelf Life",
  "lyrics": "[intro]\n(Hook-DNA: Main keyboard motif is a four-chord loop with a simple, melancholic top-line melody; repeats every four bars; anchors on the tonic of Fmaj7.)\n(Inst: Washed-out Rhodes piano with heavy chorus/vibrato; solo.)\n(Mix: Wide stereo field. Prominent low-end warmth, slightly recessed low-mids for clarity. Silky, smooth high-end. Instruments sit in a lush, medium-decay plate reverb. Very dynamic, minimal bus compression.)\n\n[verse]\n(Vocal-Perf: Low-key, almost spoken-word delivery; close-mic'd with audible breath sounds.)\n(Melody-Rhythm: Vocal phrases start on the 'and' of beat 2, weaving around the sparse kick pattern.)\n(Melody-Contour: Primarily monadic with slight upward inflections at the end of lines.)\n(Chords: Fmaj7 - Gm7 - Am7 - Gm7)\n(Inst: Rhodes piano continues; a deep 808 sub-kick and crisp, dry snare enter, creating a sparse backbeat. Skittering 16th-note hi-hats provide forward momentum.)\nStill got your hoodie folded on the second shelf\nLeft it there like evidence, kept it to myself\nSmells like somewhere between apology and sleep\nSome debts you never settle, some things you never keep\nI rehearsed the whole goodbye in the bathroom mirror\nBy the time you knocked, none of it came out clearer\nSo I handed you the keys and I kept the silence\nSomething in the quiet felt like a slow compliance\n\n[chorus]\n(Vocal-Perf: Shifts to a smooth, melodic sung vocal; airy backing vocal layers enter, subtly panned.)\n(Hook-DNA: Core motif is a descending two-note phrase on \"two ways\"; repeats twice with identical rhythm; anchors on the 5th of the scale.)\n(Melody-Contour: Gentle arch shape, starts on the 5th, dips to the 2nd, resolves back to the 3rd.)\n(Melody-Harmonic-Tension: The first note of the main phrase creates a brief, pleasing dissonance (the 9th) over the root chord, resolving down by a step on the next beat.)\n(Chords: Fmaj7 - Gm7 - Am7 - Gm7)\n(Mix: Vocal layers widen the stereo image; snare has a touch more reverb.)\nStill on the shelf, collecting all this dust\nWe were good at holding on but terrible at trust\nMaybe loving slow is just another way to rust\nStill on the shelf, still on the shelf\n\n[verse]\n(Vocal-Perf: Returns to the conversational, rhythmic flow of the first verse, slightly more energy.)\n(Melody-Rhythm: Tighter syncopation, more words per bar, pushing the beat slightly.)\n(Melody-Contour: Still relatively flat, but with more dynamic variation between soft and loud syllables.)\n(Inst: All elements from previous sections continue; a very subtle, low-passed synth pad with a slow attack floats underneath.)\nFound the birthday card you wrote in purple ink\nRead it on a Tuesday standing at the sink\nYou said forever like it was a grocery list\nNow it's just a word dissolving in the mist\nI don't hate you, that's the part that takes the most\nCause hating is a fever and I'm running cold\nJust a drawer full of receipts for things we spent\nAnd neither one of us can say where all of it went\n\n[chorus]\n(Vocal-Perf: Stronger delivery than the first chorus; backing vocal harmonies are more prominent and complex.)\n(Hook-DNA: Core motif is a descending two-note phrase on \"two ways\"; repeats twice with identical rhythm; anchors on the 5th of the scale.)\n(Melody-Contour: Gentle arch shape, starts on the 5th, dips to the 2nd, resolves back to the 3rd.)\n(Melody-Harmonic-Tension: The first note of the main phrase creates a brief, pleasing dissonance (the 9th) over the root chord, resolving down by a step on the next beat.)\n(Chords: Fmaj7 - Gm7 - Am7 - Gm7)\n(Mix: Drums hit slightly harder with parallel compression; lead vocal has a short, syncopated slap delay.)\nStill on the shelf, collecting all this dust\nWe were good at holding on but terrible at trust\nMaybe loving slow is just another way to rust\nStill on the shelf, still on the shelf\n\n[bridge]\n(Vocal-Perf: Shifts into an airy, intimate falsetto; delivery is legato and smooth.)\n(Melody-Harmonic-Tension: Melody floats over the changes, sustaining notes (the 7th and 9th) across bar lines, creating a dreamy, unresolved feeling that only settles on the final word.)\n(Chords: Dm7 - Gm7 - C7 - Fmaj7)\n(Inst: Drums drop out, leaving only the Rhodes and the washy synth pad. A reversed piano swell transitions into the section.)\nDo we keep the shape\nOf something after it's already lost its weight?\nI leave the light on low\nFor someone who stopped coming home\n\n[outro]\n(Vocal-Perf: Main vocal drops out completely. A new, high-pitched and heavily processed vocal sample becomes the lead instrument.)\n(Hook-DNA: The pitched-up vocal sample sings a simple, repetitive 4-note motif that cycles over the chord progression, creating an earworm hook.)\n(Inst: Drums re-enter with the same sparse pattern. Rhodes and pads continue as the track slowly fades out over 8 bars.)\n(Mix: A low-pass filter is slowly applied to the entire mix, making it sound distant as it fades.)\n(pitched vocal melody)\nOn the shelf… on the shelf…\nCollecting dust… collecting dust…\n",
