  "prompt": "Genre: Country Pop; BPM: 102; Key: F# Major; Rhythm: Mid-tempo, trap-influenced pop groove with a clean 808-style kick on 1 & 3, crisp layered snare/clap on 2 & 4, and busy, slightly swung 16th-note hi-hats.; Instruments: Bright, close-mic'd acoustic guitar with crisp string attack; Clean electric guitar with ambient reverb swells; Smooth, deep 808-style sub bass; Programmed drums: punchy 808 kick, layered clap/snare, crisp 16th-note hats; Warm; Vocals: Male with a modern country twang and a slight rasp, shifting from conversational verse delivery to an emotionally weighted chest voice in the chorus, featuring lush background vocal stacks.; Highlight: The moment the track begins with only a sparse, arpeggiated acoustic guitar for 8 bars, creating a sense of intimacy before the full beat and brain-scratching melodic hook drop in unexpectedly on the downbeat.",
  "title": "Wren County Road",
  "lyrics": "[intro]\n(Mix: Spacious, wide stereo field. Lows are powerful but controlled via 808 sub. Mids are clean, focused on acoustic guitar. Highs are smooth, dominated by crisp hi-hats. Vocals will sit front-and-center with light compression.)\n(Inst: Close-mic'd acoustic guitar arpeggio.)\n\n[chorus]\n(Hook-DNA: Vocal phrases start on upbeat of 4, syncopating across the bar line; Melody centers around 3rd and 5th, resolving to root; Main phrase repeats, second half acts as response.)\n(Melody-Contour: Mostly stepwise motion with a key descending minor 3rd on signature phrases, creating a conversational feel.)\n(Melody-Rhythm: Relaxed, behind-the-beat phrasing, heavy syncopation, like storytelling.)\n(Melody-Harmonic-Tension: Melody holds the 2nd over the V chord on '...never met', delaying resolution.)\n(Vocal-Perf: Conversational but emotionally weighty chest voice, slight country twang.)\n(Inst: Full band enters: 808 sub, layered clap/snare, 16th-note hats, subtle pads.)\n(Chords: F# - C# - D#m - B)\n(Mix: Wider stereo image, vocals layered with lush harmonies, parallel compression on drum bus.)\nI left my jacket on your porch swing, third summer in a row\nKept telling myself I'd come collect it, but darlin' you and I both know\nThere's a version of this story where I finally let it go\nBut something in my chest won't turn me toward that Wren County road\n\n[verse]\n(Vocal-Perf: More intimate, lower in register, almost spoken delivery.)\n(Inst: Beat strips back, hi-hat pattern simplifies, acoustic guitar more prominent.)\n(Chords: F# - C# - D#m - B)\nYour momma's wind chimes still hang crooked on the eave\nI drove past Tuesday, didn't slow, but I could hear them breathe\nSaw the yellow light still burning through your kitchen curtain seam\nTold myself it meant nothing\nKept on driving, gripped the wheel, kept on lying to me\n\n[chorus]\n(Hook-DNA: Vocal phrases start on upbeat of 4, syncopating across the bar line; Melody centers around 3rd and 5th, resolving to root; Main phrase repeats, second half acts as response.)\n(Melody-Contour: Mostly stepwise motion with a key descending minor 3rd on signature phrases, creating a conversational feel.)\n(Melody-Rhythm: Relaxed, behind-the-beat phrasing, heavy syncopation, like storytelling.)\n(Melody-Harmonic-Tension: Melody holds the 2nd over the V chord on '...never met', delaying resolution.)\n(Vocal-Perf: Increased intensity and rasp, backing vocals more prominent.)\n(Inst: Full dynamic range, electric guitar swells more audible.)\n(Chords: F# - C# - D#m - B)\nI left my jacket on your porch swing, third summer in a row\nKept telling myself I'd come collect it, but darlin' you and I both know\nThere's a version of this story where I finally let it go\nBut something in my chest won't turn me toward that Wren County road\nI can't make myself go\n\n[bridge]\n(Melody-Contour: Melody ascends, building tension, higher register than chorus.)\n(Melody-Harmonic-Tension: Holds on the 6th over the IV chord ('...had enough'), creating a pleading, unresolved feeling before resolving down.)\n(Vocal-Perf: Most strained and emotional delivery, pushing top of range.)\n(Inst: Drums drop out for first two lines, leaving vocals, pads, and guitar. Full beat re-enters with force.)\n(Chords: B - D#m - C# - F#)\nI've been moving boxes into somewhere new and painting over walls\nBut I still sleep on your side of the bed when nobody calls\nThree years of learning how to be a stranger to your name\nAnd I'm parked outside your neighborhood again, feeling the same\n\n[outro]\n(Vocal-Perf: Fades out with ad-libs, intimate and reflective.)\n(Inst: Instrumentation gradually thins out, ending with the solo acoustic guitar arpeggio, mirroring the intro.)\n(Chords: B - F# - C# - F#)\n(Sound-Design: Final acoustic chord has a long, natural reverb tail.)\nThat jacket's still there, I can feel it in the cold\nSomething in my chest won't turn me toward that Wren County road\nI can't make myself go\nI can't make myself go\n",
  "cover_prompt": "生成一张无字音乐专辑封面。风格参照日本「もの派」（Mono-ha）的物质感与李禹焕（Lee Ufan）绘画中「留白与一笔」的克制美学，结合湿拓画（Ebru / paper marbling）的有机纹理。画面核心：一件褪色的浅卡其色外套轮廓，以极稀薄的墨水线条勾勒，悬浮于从干草黄渐变至雾灰色的宣纸背景中央偏下——外套边缘在湿纸上自然晕开，如同被秋日水汽慢慢吸收，形状可辨但细节消融。背景大面积留白，带有手工棉纸的细腻纤维纹理与隐约水渍痕迹，右上角透出极淡的暖琥珀色，模拟一扇远处黄色窗光透过雾气的朦胧残影，但不出现任何窗框或建筑轮廓。整体构图极度克制，外套主体偏离中心居于画面下三分之一，大量留白向上延伸，制造一种悬而未决的漂泊感。整体像一张被扫描的实体版画作品（scanned fine art print），而非数字生成图像。技法要求：几何图形的边缘必须是颜料在湿润纸面上自然扩散形成的（ink bleeding on wet paper），而非数字绘制的精准轮廓。背景需要呈现真实手工纸的纤维质感（visible paper fibers, deckled edges texture），可以带有轻微的水渍痕迹（watermark stains）和纸张泛黄的老化感。构图极度克制，大面积留白，主体偏离中心（off-center composition）。绝对禁止：任何文字/字母/拼音、人物或人物轮廓、复杂场景、风景照片感、3D渲染、塑料质感的光泽。",
