  "prompt": "Genre: K-Pop/Funk Fusion with Jazzy R&B undertones; BPM: 144; Key: G Major; Rhythm: Tight, syncopated funk groove driven by a melodic bassline and a sparse kick/snare pattern against busy 16th-note hi-hats, creating a driving pocket syncopation; Instruments: Dry DI electric bass, minimal room tone, Close-mic'd dry drum kit, tight gate, Chorused Rhodes piano; Vocals: Female, light and breathy conversational tone, shifting to assertive melodic lines, featuring intimate close-mic delivery and spoken-word ad-libs; Mood: Walking through a crowded gallery opening, making deliberate eye contact with people who are whispering, a small, unbothered smile on your face; Highlight: The abrupt dropout of the entire funk groove at the start of the pre-chorus, leaving a lone electric piano chord under a critical, spoken-word question.",
  "title": "Soft Radius",
  "lyrics": "[intro]\n(Mix: Centered mono lead vocal, dry. Bass-forward frequency balance, tight low-end, clean mids for vocal clarity, silky highs. Moderate compression on vocal for presence. Wide stereo field for FX and BVs.)\n(Inst: Vocal only)\n(Vocal-Perf: Conversational, welcoming but detached.)\n(Chords: N/A)\nStay easy — just so you know\n\n[verse]\n(Melody-Contour: Mostly spoken on a low, repeating pitch, with small upward inflections at phrase ends. Plateau-like.)\n(Melody-Rhythm: Rapid-fire 16th-note delivery, landing just ahead of the beat, creating tension against the steady groove.)\n(Inst: Prominent syncopated DI electric bass, Tight dry drums, Sparse Rhodes chords.)\n(Vocal-Perf: Breathy, rhythmic, almost-whispered delivery. Intimate and cool.)\n(Chords: Gmaj7 - Cmaj7 - Am7 - D7)\nKeep it smooth — no opener needed\nPull back just a little, give me breathing room, room\nI'm doing fine — it's balanced, balanced\nThis is me, exactly who I've always been\nGot your radar pinging lately — what's the signal?\nScanning every move I make — tracker, tracker\nCounting all my choices like a scoreboard — clocking, clocking\n\n[pre-chorus]\n(Transition: Abrupt full stop of the groove.)\n(Melody-Contour: Declamatory and spoken, narrow range, descending slightly at the end of each line.)\n(Melody-Rhythm: Follows natural speech rhythm, not locked to a grid.)\n(Inst: Bass and drums drop out. Only sustained Rhodes chords and a quiet pad.)\n(Vocal-Perf: Shifts to a theatrical, judgmental tone. Less breathy, more direct.)\n(Chords: Bm7 - E7 - Am7 - D7sus4)\nDid she really just show up uninvited again?\nShe's been replaying every detail since when?\nWhy does every quiet moment feel like testimony?\nBless her little heart though\n\n[chorus]\n(Hook-DNA: Rhythmic motif is \"long-long-short-short\" (Yel-low C A R D). Anchors around the 5th and 3rd of the key. Motif repeats with slight melodic variation for each line.)\n(Melody-Contour: Arch-shaped phrases, starting low, ascending a perfect 4th on \"ma ma ma mine\", then descending.)\n(Melody-Rhythm: Syncopated, with the main hook words landing squarely on the downbeats for emphasis.)\n(Melody-Harmonic-Tension: The word \"line\" in \"la la la line\" lands on the 7th over the tonic chord, holding tension before resolving. The phrase \"we don't know\" hovers on the 2nd over the tonic chord, creating a floaty, unresolved feeling.)\n(Inst: Full funk band returns. Driving bassline. Synth pluck accentuates rhythm. Sharp synth \"beep\" SFX.)\n(Vocal-Perf: More melodic and assertive, with tight, layered backing vocals.)\n(Chords: Gmaj7 - Am7 - Bm7 - Am7)\n(Mix: Wider stereo image. Backing vocals panned wide. \"Beep\" FX cuts through hard-panned.)\nSoft R A D I U S\nStep inside it and it's trespass, beep\nGot a soft radius — it's ma ma ma mine\nPlease keep the fa fa fa fine\nWatch your S T E P\nCross the edge and we go cold — beep\nBack up, know your lane, cause we don't know know know know\nComma we don't owe owe owe owe\n\n[verse]\n(Melody-Contour: Plateau-like, spoken on a low, repeating pitch.)\n(Melody-Rhythm: Rhythmic 16th-note phrasing, weaving around the bassline.)\n(Inst: Groove identical to first verse. Subtle synth pad added.)\n(Vocal-Perf: Returns to the cool, detached, breathy delivery.)\n(Chords: Gmaj7 - Cmaj7 - Am7 - D7)\n(Mix: Narrows back to the verse focus.)\nI don't share — the password to my headspace\nEverybody's got their own story anyway\nPolitely stepping back now — not your chapter\nI'm easy — talk less, talk less\nStill me — no plot twist, nothing changed here\nBet you're drafting something clever in that group chat\nCataloging my stillness — screenshot, screenshot\nBuilding up a case from nothing — log log logging\n\n[pre-chorus]\n(Transition: Another abrupt stop.)\n(Melody-Contour: Spoken, slightly more animated than the first pre-chorus.)\n(Melody-Rhythm: Free, conversational timing.)\n(Inst: Groove drops out, sustained Rhodes chords.)\n(Vocal-Perf: Again, theatrical and gossipy tone.)\n(Chords: Bm7 - E7 - Am7 - D7sus4)\nWalking so composed but secretly fuming, right?\nDoes she even hear what everybody's saying tonight?\nRunning with a crowd that's gonna drag her down, I'm sure\nWorry for her though\n\n[chorus]\n(Hook-DNA: Rhythmic motif \"long-long-short-short\" (Yel-low C A R D). Anchors around the 5th and 3rd. Repeats with variation.)\n(Melody-Contour: Arch-shaped phrases, ascending a P4.)\n(Melody-Rhythm: Syncopated, hook words on downbeats.)\n(Melody-Harmonic-Tension: Melody on \"line\" lands on the 7th over the tonic chord. Phrase \"we don't know\" hovers on the 2nd over the tonic chord, creating unresolved tension.)\n(Inst: Full band, driving bass, synth pluck, \"beep\" SFX.)\n(Vocal-Perf: Assertive and melodic, tight BVs.)\n(Chords: Gmaj7 - Am7 - Bm7 - Am7)\n(Mix: Mix widens for impact, BVs panned.)\nSoft R A D I U S\nStep inside it and it's trespass, beep\nGot a soft radius — it's ma ma ma mine\nPlease keep the fa fa fa fine\nWatch your S T E P\nCross the edge and we go cold — beep\nBack up, know your lane, cause we don't know know know know\nComma we don't owe owe owe owe\n\n[bridge]\n(Melody-Contour: Rhythmic speech, mostly monotonous with sharp upward inflections for questions.)\n(Melody-Rhythm: Complex, syncopated rap flow that plays against a stripped-down beat.)\n(Melody-Harmonic-Tension: Rhythmic tension created by vocal phrasing pushing and pulling against the static beat and harmony, creating friction.)\n(Inst: Beat simplifies to kick, clap, and a pulsing, filtered bass synth. Vocal chops as counterpoint.)\n(Vocal-Perf: Attitude-filled, confrontational rap delivery with vocal fry and grit.)\n(Chords: Am7 - D7 repeated vamp)\n(Mix: Drier, more claustrophobic. Vocals are aggressive and in-your-face.)\nGo ahead though\nHey — you in the back — you catching all this? Yeah?\nNah, you still don't get it\nSo I'm wrong again? Or are you just projecting? Yeah?\nRead the room — you got zero chill — knock knock knock\nDone talking — muting all of this — block block block block block\nIf the concept still escapes you, let me spell it, babe\nRepeat, repeat\nPretty simple, right",
