  "prompt": "Genre: Contemporary R&B; BPM: 110; Key: D minor; Rhythm: Heavy, dramatic half-time pop-rock groove with a powerful kick on 1 and a heavy snare/clap on 3, creating a marching, anthemic feel; Instruments: Layer 1 (Melodic Core): Melancholic grand piano playing powerful block chords. Layer 2 (Rhythm Foundation): Punchy, live-sounding acoustic drum kit with a deep kick and resonant snare; clean, subby electric bass following the root notes. Layer 3 (Harmonic Glue): Epic, swelling orchestral string section and layered choir-like vocal pads adding drama in the chorus; Vocals: Male R&B Vocalist; powerful tenor with a wide dynamic range, moving from a restrained, breathy verse to a raw, emotional, full-throated belt in the chorus, characterized by a pained vocal 'cry'; Mood: Toxic relationship reflection; Highlight: The raw, powerful, and emotionally strained belted vocal performance in the chorus that drives home the theme of desperate sacrifice.",

  "lyrics": "[verse]\n(Chords: Dm - Bb - F - C)\n(Inst: Isolated grand piano, light reverb. Bass enters halfway.)\n(Mix: Piano wide, vocal dry and centered.)\n(Motif-Anatomy: Rhythmic, percussive vocal phrasing, mostly one-note melody.)\n(Phrase-Structure: Symmetrical 4-bar phrases, conversational rhythm.)\n(Contour-&-Range: Low-to-mid register chest voice, restrained.)\n(Vocal-Perf: Pained, slightly breathy delivery, clear enunciation, subtle vocal fry on line ends.)\nI left the city lights to find myself\nPacked my silence on a shelf\nThought the miles could make me new\nWoke up three states deep and still thought of you\n\n[pre-chorus]\n(Chords: Bb - C - Dm - C)\n(Transition: Drums enter with a simple fill, kick and hi-hats only.)\n(Sound-Design: Subtle string swell begins, building tension.)\n(Motif-Anatomy: Melody begins to ascend, holding longer notes.)\n(Phrase-Structure: Two short phrases building to a held note.)\n(Contour-&-Range: Ascends into upper-mid register, adds intensity.)\n(Vocal-Perf: Voice gains power, less breathy, more forward placement.)\nI erased your name but not the way it sounded\nNow I'm somewhere new and still feel grounded\n\n[chorus]\n(Chords: Dm - Bb - F - C)\n(Transition: Full drum kit crashes in, snare/clap on 3.)\n(Sound-Design: Choir pads and full string section create an epic wall of sound.)\n(Inst: Full band enters, driving piano chords, heavy bass.)\n(Mix: Vocals layered with harmonies, wide stereo field, drenched in hall reverb.)\n(Motif-Anatomy: Soaring, anthemic melody with sustained high notes.)\n(Phrase-Structure: Powerful, declarative 4-bar phrases.)\n(Contour-&-Range: Leaps to high tenor range, full power belt.)\n(Vocal-Perf: Raw, powerful, strained emotional belt, distinct vocal 'cry' on key words.)\nI drove until the highway had no name\nTried to outrun who I became\nYeah, I swore I was over it\nBut the dark kept speaking with your face in it\nAnd I'm screaming at a rearview mirror, what's the point\nIf leaving you just means I fall apart\n\n[verse]\n(Chords: Dm - Bb - F - C)\n(Inst: Band strips back to piano, bass, and a simpler beat.)\n(Mix: Vocals return to a drier, more intimate setting.)\n(Motif-Anatomy: Returns to rhythmic, percussive vocal phrasing.)\n(Phrase-Structure: Symmetrical 4-bar phrases, story-telling.)\n(Contour-&-Range: Back down to low-to-mid register.)\n(Vocal-Perf: Resigned, pained tone, almost spoken at times.)\nMotel room, a faded number on the door\nI don't even know what I came here for\nPoured a drink I didn't want and let it sit\nWondered if you ever thought about it\n\n[pre-chorus]\n(Chords: Bb - C - Dm - C)\n(Transition: Drum fill re-introduces the build.)\n(Sound-Design: String swell returns, more prominent.)\n(Motif-Anatomy: Melody ascends again, mirroring the first pre-chorus.)\n(Phrase-Structure: Two short phrases building anticipation.)\n(Contour-&-Range: Rises in pitch and intensity.)\n(Vocal-Perf: Voice becomes more forceful, pushing towards the chorus.)\nI rehearsed goodbye a hundred different ways\nAnd still I'm drowning in the aftermath of days\n\n[chorus]\n(Chords: Dm - Bb - F - C)\n(Transition: Explosive entry of full band, bigger than the first.)\n(Sound-Design: Heavier clap layer on the snare, more harmony layers.)\n(Inst: Full, powerful instrumentation.)\n(Mix: Vocals pushed even higher, harmonies wider.)\n(Motif-Anatomy: Soaring, anthemic melody with sustained high notes.)\n(Phrase-Structure: Powerful, declarative 4-bar phrases.)\n(Contour-&-Range: Jumps to powerful high tenor belt.)\n(Vocal-Perf: Desperate, emotional belt, ad-libbed vocal run at the end.)\nI drove until the highway had no name\nTried to outrun who I became\nYeah, I swore I was over it\nBut the dark kept speaking with your face in it\nAnd I'm screaming at a rearview mirror, what's the point\nIf leaving you just means I fall apart\n\n[bridge]\n(Chords: Bb - F - C - Dm)\n(Inst: Music drops to just arpeggiated piano and strings.)\n(Mix: Very sparse, atmospheric, vocals intimate with long reverb tails.)\n(Motif-Anatomy: Melancholy, descending melody.)\n(Phrase-Structure: Longer, more flowing lyrical phrases.)\n(Contour-&-Range: Softer, falsetto-tinged head voice.)\n(Vocal-Perf: Vulnerable, breathy, almost a whisper, builds back to chest voice.)\nMaybe freedom's just another word\nFor standing still and pretending you've moved on\nAnd the version of myself I'm searching for\nWas buried somewhere long before I drove this far\n\n[outro]\n(Chords: Dm - Bb - F - C)\n(Transition: Final chorus hits at full power.)\n(Sound-Design: Final cymbal crash into sustained piano chord.)\n(Inst: Full band for one last powerful chorus, then fades to a single piano.)\n(Mix: Wide and epic, then quickly narrows to mono piano.)\n(Motif-Anatomy: Repetitive, fading vocal hook.)\n(Phrase-Structure: Fragmented, repeating phrases.)\n(Contour-&-Range: High belt, then descends into a soft, low murmur.)\n(Vocal-Perf: One last powerful belt, then fades out with a resigned, broken repetition.)\nYeah, I swore I was over it\nBut the dark kept calling out your name again!\nOver it... never was...\nStill falling down... yeah...\nStill falling down...",
