  "prompt": "Genre: Synth-Pop, Dance-Pop, driving club anthem; BPM: 88; Key: C Major (relative minor feel in verses); Rhythm: Driving four-on-the-floor beat, syncopated 16th-note synth arpeggio, energetic bass bounce; Instruments: Layer 1 (Melodic/Sample Core): Bright, arpeggiated synth lead (Prophet-5 emulation) creating rhythmic hook, distorted electric guitar riffs in bridge. Layer 2 (Rhythm Foundation): Punchy electronic kick, snappy snare, tight hi-hats (80s-inspired kit), deep Moog-like synth bass. Layer 3 (Harmonic/Production Glue): Wide, shimmering synth pads, bright synth chords, atmospheric reverb tails on vocals. Vocals: Female; intimate, slightly breathy delivery in verses transitioning to powerful, confident belting in choruses; layered background vocals for anthemic feel; modern pop auto-tune, reverb, and delay. Mood: Neon-lit dancefloor, 3 AM late-night drive; Highlight: The driving, arpeggiated synth lead in the chorus combined with the dramatic shift to powerful belting.",

  "lyrics": "[intro] (Chords: Am - G - C - F) (Transition: Beat builds with pulsing synth arpeggio, kick drum introduces four-on-the-floor) (Sound-Design: Filter sweep opening on main arpeggiator, subtle white noise riser) (Inst: Arpeggiated synth, subtle synth pad, electronic drums building up)\n[verse] (Chords: Am - G - C - F) (Motif-Anatomy: Syncopated 8th-note vocal phrasing, conversational; Verse: rapid low-register chest voice) (Phrase-Structure: Symmetrical 4-bar pop phrasing, lyrical storytelling) (Contour-&-Range: Mostly mid-range, slightly descending melodic contour at phrase ends) (Vocal-Perf: Intimate, breathy female vocal, close-mic with subtle vocal fry; slight auto-tune for polish) (Mix: Vocals upfront and centered; synth bass prominent; drums driving but subtle)\nNeon signs bleed through the blinds at two\nI know I shouldn't but I'm texting you\nSweet disaster, lips like gasoline\nI know the price and I'm still paying clean\n[pre-chorus] (Chords: F - G - Am - C) (Transition: Energy builds, additional synth layers enter) (Sound-Design: Light snare roll leading into chorus, synth pad swells) (Motif-Anatomy: Rising melodic line creating tension; escalating vocal energy) (Phrase-Structure: Slightly more urgent, direct phrasing; builds towards resolution) (Contour-&-Range: Gradual melodic ascent, higher chest voice notes) (Vocal-Perf: More assertive delivery, increased chest voice power, layered harmonies introduced) (Mix: Drums become more active; synth arpeggio becomes more pronounced; vocals layered and wider)\nBurning slow, watch the ashes fall\nI keep building walls just to watch you climb them all\n[chorus] (Chords: C - G - Am - F) (Transition: Massive beat drop, main synth arpeggio at full intensity) (Sound-Design: Dramatic beat drop, heavily sidechained synths, big reverb on vocals) (Motif-Anatomy: Soaring, sustained pop-anthem melody with rhythmic synth arpeggio; Chorus: leaps an octave into powerful belting) (Phrase-Structure: Driving, repetitive 4-bar melodic hook; strong rhythmic emphasis) (Contour-&-Range: Wide vocal range, powerful high chest voice belting, soaring melodic leaps) (Vocal-Perf: Full-chest power belt, confident and commanding, multiple vocal layers; sustained notes with subtle vibrato) (Mix: Vocals wide, upfront with big reverb; drums punchy; synth bass deep and driving; main arpeggio prominent and wide)\nHeartbreak throws the dice, heaven shuts its eyes\nEvery scar you leave just makes me crave the knife\nAnd it burns, the glass of every hour\nIt bends, the weight of wanting power\nAnd it's oh, whoa oh\nThese are glass hours\nI'm fine, at least that's what I tell them\nNo lines between the hurt and heaven\nBut oh, whoa oh\nThese are glass hours\n[verse] (Chords: Am - G - C - F) (Transition: Drums slightly pull back, synth arpeggio becomes sparser) (Sound-Design: Synth pad fades slightly, drums reduce complexity) (Motif-Anatomy: Return to conversational, slightly subdued vocal phrasing; Verse: rapid low-register chest voice) (Phrase-Structure: Symmetrical 4-bar pop phrasing, lyrical storytelling) (Contour-&-Range: Similar to previous verse, mid-range delivery) (Vocal-Perf: Intimate, breathy female vocal, close-mic, slightly melancholic tone) (Mix: Vocals dry and upfront; bass prominent; drums less busy)\nParking lot confessions, dashboard confessional\nI'm not breaking, just bending past the edge\nWe promised we'd stop lighting all these matches\nBut the flame's the only warmth I have left\nSo lock the doors and kill the high beams\nI keep pretending there's a version where we don't combust\n[bridge] (Chords: F - G - Am - C) (Transition: Builds emotionally and dynamically; distorted guitar enters prominently) (Sound-Design: Guitar riff punctuates lines, vocal echoes, dynamic drum build-up) (Motif-Anatomy: Emotional, narrative-driven melody; more irregular phrasing for dramatic effect) (Phrase-Structure: Slightly asymmetrical, building intensity towards climax) (Contour-&-Range: Emotional vocal cracks and dynamic shifts; full chest voice, reaching for higher notes) (Vocal-Perf: Raw, emotional delivery, belting with slight strain for dramatic effect; layered vocal harmonies in climax) (Mix: Distorted electric guitar prominent; drums get heavier; vocals pushed to forefront with emotional processing)\nI'm wrecked on the bathroom floor\nMascara running like a thunderstorm\nSaid \"It's nothing,\" but it's everything\nI don't wanna keep pretending just to keep you near\nAnd I climbed in through your fire escape\nEvery single night I knew I'd break\nAnd I whispered, \"For whatever this is worth\nI need you, and that's the scariest thing I've ever heard\"\nYou look back, smiling through the wreckage\n[chorus] (Chords: C - G - Am - F) (Transition: Return to full energy after bridge climax, powerful drop) (Sound-Design: Massive beat drop, main synth arpeggio at full intensity, increased vocal layering) (Motif-Anatomy: Soaring, sustained pop-anthem melody with rhythmic synth arpeggio; Chorus: leaps an octave into powerful belting) (Phrase-Structure: Driving, repetitive 4-bar melodic hook; strong rhythmic emphasis) (Contour-&-Range: Wide vocal range, powerful high chest voice belting, soaring melodic leaps; even more commanding) (Vocal-Perf: Full-chest power belt, confident and commanding, maximal vocal layers; sustained notes with prominent vibrato) (Mix: Vocals wide, upfront with big reverb; drums punchy; synth bass deep and driving; main arpeggio prominent and wide)\nHeartbreak throws the dice, heaven shuts its eyes\nEvery scar you leave just makes me crave the knife\nAnd it burns, the glass of every hour\nIt bends, the weight of wanting power\nAnd it's oh, whoa oh\nThese are glass hours\nI'm fine, at least that's what I tell them\nNo lines between the hurt and heaven\nBut oh, whoa oh\nThese are glass hours\n[outro] (Chords: C - G - Am - F) (Transition: Reduces intensity gradually, fades out on main synth arpeggio) (Sound-Design: Synth arpeggio loops and filters down, drums simplify and fade) (Motif-Anatomy: Lingering melodic snippets from chorus, vocal ad-libs fading) (Phrase-Structure: Fragmented, echoing phrases; gradually dissipating energy) (Contour-&-Range: Drops back to mid-range, reflective vocal delivery; final sustained notes) (Vocal-Perf: Softer, more reflective vocal with heavy delay; whispered ad-libs; fades out emotionally) (Mix: Vocals heavily delayed, fading back; synth arpeggio remains central; drums minimal, then disappear)\nWith me",
