  "prompt": "Genre: Country Pop / Pop Rock; BPM: 118; Key: D Major; Rhythm: Driving 4/4 pop-rock backbeat with a prominent snare on 2 & 4 and steady eighth-note hi-hats, creating a constant forward momentum.; Instruments: Bright banjo arpeggios; Steel-string acoustic strum; Shimmering mandolin lines; Soaring solo fiddle; Clean arpeggiated electric gtr; Overdriven power chords; Solid round DI bass; Punchy live drum kit.; Vocals: Female, youthful and clear mezzo-soprano, shifting from a conversational, narrative verse delivery to a strong, projected chorus, featuring lush background vocal stacks.; Mood: Finding an old faded photograph from a high school dance in a shoebox, the specific feeling of remembering a secret you shared with someone under the bleachers.; Highlight: The sudden dynamic shift at the proposal; the band re-enters on a new, higher key center exactly as the male perspective is introduced, creating an explosive, cathartic release of narrative tension.",
  "title": "Hay Bale Summer",
  "lyrics": "[intro]\n(Mix: Full frequency spectrum, wide stereo image. Bright, plucky country instruments panned L/R over a centered, solid rhythm section foundation. Light master bus compression for cohesion.)\n(Inst: Signature banjo arpeggio, rhythmic strummed acoustic guitar, melodic mandolin counter-line.)\n(Chords: D - A - Em - G)\n\n[verse]\n(Melody-Contour: Narrow melodic range, primarily stepwise motion, creating a conversational, storytelling feel.)\n(Melody-Rhythm: Vocal phrases land gently after the downbeat, flowing with natural speech-like syncopation.)\n(Vocal-Perf: Intimate, slightly breathy, clean lead vocal, placed upfront and relatively dry.)\n(Inst: Drums enter with a simple kick-snare pattern. Bass provides a solid root-note foundation. Banjo continues its arpeggiated motif.)\n(Chords: D - A - Em - G)\nThe summer I turned seventeen the creek ran low\nYou showed me which fence post the wild grapes grow\nWe split a peach\nOn the tailgate in the August heat\nI still remember how the juice ran down your chin\nYou laughed and wiped it on your sleeve\nDidn't say a word\nJust handed half to me\n\n[chorus]\n(Hook-DNA: Ascending P4 leap on the first word is the core hook; motif repeats over changing chords, anchoring on the 5th; insistent eighth-note rhythm drives the phrase forward.)\n(Melody-Contour: Broad, arching shape, defined by the initial powerful ascending interval leap.)\n(Melody-Rhythm: Driving, on-the-beat eighth-note phrasing, pushing the energy forward.)\n(Melody-Harmonic-Tension: Melody holds a tense major 7th over the V chord before resolving down, creating a powerful sense of yearning and release.)\n(Vocal-Perf: Shifts to a powerful, open-throated belt; supported by lush background vocal stacks in tight harmony.)\n(Inst: Full band enters; overdriven electric guitars play thick power chords; soaring fiddle line adds dramatic flair; cymbals crash on downbeats.)\n(Mix: Significantly wider and denser. Parallel compression added to drums and vocals for maximum impact.)\n(Chords: D - A - Em - G)\nThat whole September I kept your flannel in my drawer\nStared at the gravel road and counted every car\nTold myself it didn't mean a thing\nBut I was lying through my teeth\nCause you were hay bale summer\nSun-bleached and wild and free\nAnd every other season since\nHas felt like it was missing me\n\n[verse]\n(Vocal-Perf: Returns to the softer, narrative tone of the first verse.)\n(Inst: Dynamics pull back to the verse arrangement, emphasizing the acoustic guitar and bass groove.)\n(Chords: D - A - Em - G)\nBy October you were gone to school three counties east\nI learned the names of all your courses\nYou learned to like the city streets\nI kept your number\nScrolled past it every Friday night\nTold my mama I was over it\nShe saw right through the lie\n\n[bridge]\n(Melody-Harmonic-Tension: Phrases consistently end on unstable chord tones (2nd or 6th) over a minor chord (Bm), creating a prolonged feeling of doubt and unresolved tension.)\n(Vocal-Perf: Becomes more pleading, with a slight strain in the voice to convey desperation.)\n(Inst: Band feels more restrained; clean electric guitar arpeggios replace the heavy power chords.)\n(Chords: G - D - A - Bm)\nMaybe I held on too tight\nTo something that was never mine to keep\nBut the peach pit in my jacket pocket\nStill smells like the week\nYou made me believe\n\n[breakdown]\n(Vocal-Perf: Becomes vulnerable, almost a whisper, conveying fading hope.)\n(Inst: All instruments drop out except for a lone, clean arpeggiated electric guitar and a swelling synth pad, creating a spacious, waiting atmosphere.)\nI packed that flannel in a box last spring\nFolded it the way you always did the corners in\nThought moving on would feel like relief\nBut the cardboard smelled like cut grass\nAnd I was seventeen again\nStanding at that tailgate\nWondering what could have been\n\n[outro]\n(Transition: A beat of complete silence before the full band explodes back in.)\n(Melody-Harmonic-Tension: A key change up a whole step (to E Major) provides the ultimate harmonic release, resolving all the song's narrative tension in a triumphant climax.)\n(Vocal-Perf: Full-voiced, joyous, and resolute delivery, sung from a new perspective.)\n(Inst: The biggest and most powerful arrangement of the song; all instrumental layers are present and at maximum energy.)\n(Mix: The loudest and widest point of the track, heavily compressed for a massive, celebratory finish.)\n(Chords: E - B - F#m - A)\nHe showed up at the door in the middle of the rain\nHeld a peach in one hand\nSaid I drove back just to say\nThat hay bale summer never left my mind\nI kept your half and I kept the rind\nSo take my word, take my worn-out heart\nThis is where our real story starts",
