  "prompt": "Genre: Country Pop Crossover Ballad; BPM: 119; Key: B♭ minor; Rhythm: Mid-tempo 4/4 with a driving pocket syncopation; big, reverb-soaked snare on 2 and 4, and a solid kick-bass lock on the downbeats.; Instruments: Arpeggiated clean DI'd E-Gtr riff; wide Marshall-stack power chords; subtle strummed steel-string acoustic; deep sub-heavy synth bass; hybrid kit with a punchy kick and massive gated reverb snare; lush, slow-attack atmospheric synth pads.; Vocals: Male and Female duet. Female lead has a clear, pop-inflected tone with controlled power. Male lead is raspy, emotive with a distinct country grit. Both use lush background vocal stacks in the chorus.; Mood: Standing alone in a crowded parking lot after the show, the ringing in your ears fading, realizing you have no one to call.; Highlight: The massive dynamic shift when the full drum kit and wall-of-sound power chords crash in on the downbeat of the first chorus, lifting the sparse verse into a stadium-sized anthem.",
  "title": "Roof Caved In",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Expansive stereo field, deep-but-tight sub-bass, and a prominent, polished vocal chain. Gated reverb on snare is a key feature, creating a vast sense of space.)\n(Inst: Clean, chorus-laden electric guitar plays a memorable syncopated arpeggio. A warm synth pad swells underneath, filling the space.)\n(Chords: B♭m - G♭ - D♭ - A♭)\n\n[verse]\n(Vocal-Perf: Female lead. Intimate, close-mic'd delivery with a touch of vocal fry on phrase endings.)\n(Inst: Simple, punchy kick and the massive gated snare enter, establishing the core groove. A deep synth bass pulses with the kick. Clean guitar riff continues as the primary melodic element.)\n(Melody-Rhythm: Conversational phrasing, often starting just after the downbeat, creating a laid-back feel against the driving rhythm.)\n(Chords: B♭m - G♭ - D♭ - A♭)\nThe radiator knocks at 6 a.m.\nSame sound you'd sleep right through without a stir\nI used to hate it, now I need it then\nIt's the only voice that doesn't sound like yours\nI've started answering questions\nYou left open in the floor\n\n[chorus]\n(Transition: Subtle reverse cymbal swell into the downbeat.)\n(Mix: Stereo image widens dramatically. Heavy parallel compression engages, making the track feel louder and punchier.)\n(Hook-DNA: The melodic phrase \"I can't love you anymore\" uses an ascending P5 leap on \"can't\" as its core emotional hook; motif repeats twice, anchoring on the tonic, creating an anthemic declaration.)\n(Melody-Contour: A powerful arch shape, starting with the upward leap and then descending stepwise.)\n(Melody-Harmonic-Tension: The melody holds the 3rd over the IV chord for a full beat, creating a sweet, unresolved tension before stepping down to the root of the I chord on the hook's payoff.)\n(Vocal-Perf: Female lead shifts to a powerful, full-chest belt. Lush background vocal stacks enter, creating thick harmonies.)\n(Inst: A wall of layered, distorted electric guitars enters playing power chords. The full drum kit with crashing cymbals creates a massive energy lift.)\n(Chords: B♭m - G♭ - D♭ - A♭)\nThe roof caved in and I'm still breathing through it\nDust in my lungs where the love used to be\nThe roof caved in and I watched myself do it\nStayed in the rubble like it still could shelter me\nI traced every rafter\nLong before the after\nOh honey how do I grieve the walls I raised\nWith my own two hands\nThe roof caved in\n\n[verse]\n(Vocal-Perf: Male lead. Raspy, gritty timbre, conveying raw emotion. Delivery remains intimate and close-mic'd.)\n(Inst: Arrangement drops back to the verse 1 texture, creating dynamic contrast.)\n(Chords: B♭m - G♭ - D♭ - A♭)\nI filled the doorframe where you used to lean\nPainted over every scuff and gouge\nThought a coat of white would keep it clean\nBut the plaster dried and I still heard you breathe\nMy shoulder blades remember the weight\nOf a hand that showed up too late\n\n[chorus]\n(Mix: Feels even larger than the first chorus, with vocal harmonies pushed slightly more forward.)\n(Vocal-Perf: Male and female leads in a powerful duet. The female vocalist takes the higher harmony, creating a soaring effect. Both are belting with full intensity.)\n(Inst: The wall-of-sound arrangement from the first chorus returns, possibly with an added synth layer for more density.)\n(Melody-Harmonic-Tension: Same tension-and-release pattern as the first chorus, but the duet harmonies make the resolution feel even more epic and conclusive.)\n(Chords: B♭m - G♭ - D♭ - A♭)\nThe roof caved in and I'm still breathing through it\nDust in my lungs where the love used to be\nThe roof caved in and I watched myself do it\nStayed in the rubble like it still could shelter me\nI traced every rafter\nLong before the after\nOh honey how do I grieve the walls I raised\nWith my own two hands\nThe roof caved in\n\n[bridge]\n(Vocal-Perf: Duet vocals become more conversational, almost a call-and-response with the harmonized \"oohs\".)\n(Inst: The heavy rhythm section and distorted guitars drop out. The clean, arpeggiated guitar returns, layered over atmospheric pads and a simple bass pulse.)\n(Melody-Harmonic-Tension: Harmony shifts to build suspense, ending phrases on the V chord. The wordless \"ooh\" melody deliberately avoids the tonic, leaving the harmony unresolved and creating anticipation.)\n(Chords: G♭ - D♭ - G♭ - A♭)\nSomewhere in the wreckage ooh\nI keep finding reasons I should stay\nTell me is it courage ooh\nOr just fear dressed up as okay\n\n[outro]\n(Vocal-Perf: Ad-libbed repetitions of the title phrase, fading with heavy reverb and delay, creating a ghostly echo.)\n(Inst: The full band re-enters for one final hit on the title line, then drops away leaving only the signature clean guitar arpeggio and fading synth pads.)\n(Mix: A slow fade out, allowing the long reverb and delay tails from the final vocal to hang in the space before decaying to silence.)\n(Chords: B♭m - G♭ - D♭ - A♭)\nThe roof caved in and I'm still breathing through it\nDust in my lungs where the love used to be\nThe roof caved in\nStill caved in, still caved in\nStayed in the rubble like it still could shelter me\nI traced every rafter\nLong before the after\nOh honey how do I grieve the walls I raised\nWith my own two hands\nNo the roof caved in\n",
