  "prompt": "Genre: Electropop / R&B / Funk Fusion; BPM: 93; Key: A minor; Rhythm: A crisp, half-time hip-hop backbeat with driving pocket syncopation from a tight kick and sharp, layered clap/snare on 2 and 4; Instruments: Funky live-played bass with synth-like processing, percussive acoustic grand piano playing rhythmic chords, 808-style drum machine with a sub-heavy kick, warm analogue synth pads, subtle arpeggiators; Vocals: Male high tenor with a smooth, breathy delivery, shifting to a more focused tone for emphasis, supported by lush background vocal stacks and crisp rhythmic ad-libs; Mood: The feeling of driving a hypercar at 3 AM through empty city streets, neon lights blurring past, a beautiful stranger in the passenger seat saying nothing; Highlight: The first 'Ha-ha-ha-ha-ha' chorus entry, where the lead vocal is suddenly replaced by a stack of processed, harmonized vocoder voices, creating a jarring, robotic counterpoint to the human verse",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix. Prominent but tight sub-bass, clean midrange, silky controlled high-end. Wide stereo image with centered core elements. Dynamic, punchy compression. Expensive reverb and delay sends.)\n(Inst: Analogue synth swell, low-pass filter opening)\n(Sound-Design: Ethereal atmospheric rise)\n\n[verse]\n(Hook-DNA: Repetitive, syncopated 8-bar melodic phrase; anchors on the root note; repeats with slight rhythmic variations)\n(Melody-Contour: Mostly descending, conversational, small melodic range within a minor third)\n(Melody-Rhythm: Phrases begin after beat 1, weaving around the backbeat with heavy syncopation)\n(Vocal-Perf: Breathy, close-mic'd, effortless high tenor delivery, almost spoken)\n(Chords: Am7 - G - Cmaj7 - Fmaj7)\n(Inst: Tight 808 kick, sharp clap, funky bassline, percussive piano chords)\nI'm tryna put you in the worst mood ah\nP1 cleaner than your church shoes ah\nMilli point two just to hurt you ah\nAll red Lamb' just to tease you ah\nNone of these toys on lease too ah\nMade your whole year in a week too yah\nMain ***** outta your league too ah\nSide ***** outta your league too ah\n\n[pre-chorus]\n(Melody-Contour: Ascending line, building tension towards chorus, wider melodic range than verse)\n(Melody-Rhythm: More on-the-beat phrasing, less syncopated, driving forward)\n(Vocal-Perf: More projection and melodic focus than verse, less breathiness)\n(Chords: Am7 - G - Cmaj7 - Fmaj7)\n(Inst: Warm synth pad swells underneath to build energy)\nHouse so empty need a centerpiece\nTwenty racks a table cut from ebony\nCut that ivory into skinny pieces\nThen she clean it with her face man I love my baby ah\nYou talkin' money need a hearin' aid\nYou talkin' 'bout me I don't see the shade\nSwitch up my style I take any lane\nI switch up my cup I kill any pain\n\n[chorus]\n(Hook-DNA: 5-note staccato eighth-note motif (\"ha-ha-ha-ha-ha\"); melody descends stepwise following chords; motif repeats twice, then varies for resolution)\n(Melody-Contour: Arch shape over the full phrase, peaking on the line \"Look what you've done\")\n(Melody-Rhythm: Rhythmic motif is rigidly on-beat, contrasting with syncopated verse)\n(Melody-Harmonic-Tension: Vocal stacks on the hook use diatonic notes that create momentary dissonance against the bass movement, resolving on the last note of each 5-note group)\n(Vocal-Perf: Lead vocal layered with dense, wide, heavily processed vocoder/synth vocal stacks on the hook)\n(Chords: Am7 - G - Cmaj7 - Fmaj7)\n(Inst: All elements present, synth pad more prominent)\n(Mix: Stereo image widens significantly, vocals become immense, parallel compression adds weight)\nHa-ha-ha-ha-ha ha-ha-ha-ha-ha\nLook what you've done\nHa-ha-ha-ha-ha ha-ha-ha-ha-ha\nI'm a ************* starboy\n\n[verse]\n(Melody-Contour: Same descending, conversational contour as first verse)\n(Melody-Rhythm: Continues the syncopated, behind-the-beat phrasing)\n(Vocal-Perf: Returns to breathy, intimate delivery)\n(Chords: Am7 - G - Cmaj7 - Fmaj7)\n(Inst: Same instrumentation as first verse)\n(Mix: Narrows back to the verse pocket)\nEvery day a nigga try to test me ah\nEvery day a nigga try to end me ah\nPull off in that Roadster SV ah\nPockets overweight gettin' hefty ah\nComin' for the king that's a far cry I\nI come alive in the fall time I\nThe competition I don't really listen\nI'm in the blue Mulsanne bumpin' New Edition\n\n[pre-chorus]\n(Melody-Contour: Ascending line, builds tension again)\n(Vocal-Perf: Shifts to more focused, melodic tone)\n(Chords: Am7 - G - Cmaj7 - Fmaj7)\n(Inst: Synth pad swells again)\nHouse so empty need a centerpiece\nTwenty racks a table cut from ebony\nCut that ivory into skinny pieces\nThen she clean it with her face man I love my baby ah\nYou talkin' money need a hearin' aid\nYou talkin' 'bout me I don't see the shade\nSwitch up my style I take any lane\nI switch up my cup I kill any pain\n\n[bridge]\n(Melody-Contour: New melodic idea, higher register, more sustained notes)\n(Melody-Rhythm: Slower, more legato phrasing, less percussive)\n(Melody-Harmonic-Tension: Melodic phrases end on the 3rd or 5th of the chord, creating a feeling of suspension and harmonic space before the final chorus payoff)\n(Vocal-Perf: Smooth, confident delivery, less rhythmic, more sung)\n(Chords: Am7 - G - Cmaj7 - Fmaj7)\n(Inst: Bassline becomes more melodic, piano becomes more sparse)\n(Mix: Slightly stripped back, creating a dynamic dip)\nLet a nigga brag Pitt\nLegend of the fall took the year like a bandit\nBought Mama a crib and a brand new wagon\nNow she hit the grocery shop lookin' lavish\nStar Trek roof in that Wraith of Khan\nGirls get loose when they hear this song\nA hundred on the dash get me close to God\nWe don't pray for love we just pray for cars\n\n[chorus]\n(Hook-DNA: 5-note staccato eighth-note motif (\"ha-ha-ha-ha-ha\");
