  "prompt": "Genre: Indie Folk-Pop / Americana; BPM: 164; Key: F# minor; Rhythm: Propulsive, fast-paced folk shuffle with a driving kick on every beat and a syncopated snare pattern creating relentless forward momentum.; Instruments: Strummed acoustic, audible pick attack; Live drum kit, punchy kick, tight snare; Clean electric bass, pick-style playing; Clean electric gtr; Vocals: Male, raw and raspy tenor, moving from a conversational verse delivery to a strained, powerful chest belting in the chorus, featuring lush background vocal stacks.; Mood: The feeling of talking too fast in a cold car, windows fogging up, knowing you're pushing someone away but unable to stop.; Highlight: The dynamic explosion on the downbeat of the first chorus, where the full band and stacked vocals crash in, transforming the energy from a sparse, anxious verse to a massive, anthemic wall of sound.",
  "title": "White Knuckle Summer",
  "lyrics": "[intro]\n(Inst: Hard-strummed acoustic guitar R channel; Clean arpeggiated electric guitar L channel; Driving four-on-the-floor kick drum pattern enters.)\n(Mix: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Wide stereo image with distinct panning. Dynamic, punchy low-end from kick and bass. Vocals will be dry and centered in verses, expanding with plate reverb in chorus.)\n\n[verse]\n(Hook-DNA: Verse rhythm is built on relentless, palm-muted 16th-note acoustic strumming, creating a tense, forward-leaning pulse; melodic phrases are short and clipped, landing squarely on the beat; the entire section functions as a coiled spring before the chorus release.)\n(Melody-Contour: Narrow melodic range, mostly stepwise motion with a plateau shape, mirroring a frantic speaking cadence.)\n(Melody-Rhythm: Rapid, syllabic delivery with phrases starting on the downbeat, minimal space between lines enhances the feeling of breathlessness.)\n(Inst: Acoustic guitar and kick drum foundation; Clean electric bass enters, playing driving root notes.)\n(Vocal-Perf: intimate close-mic, low-volume, raspy and confessional tone, with audible breaths between phrases.)\n(Chords: F#m - A - D - A)\nI learned to pack a bag before the argument was done\nTwo shirts, a toothbrush, leave before the sun\nMy mother ran the same arithmetic\nSubtract yourself before they count the cost of it\nSo I stayed light, I stayed fast, I stayed clean\nAnd every town I landed in I left without a seam\nUntil that August when your porch light caught my face\nAnd something in my chest forgot to stay in place\n\n[chorus]\n(Hook-DNA: brain-scratching melodic hook follows a distinct rhythmic pattern of eighth-note runs followed by a held half-note on the peak of the phrase (e.g., \"...a-HEAD\"); pitch anchors around the 5th (C#) and uses the high root (F#) as its climax; the motif repeats twice before a concluding tail phrase.)\n(Melody-Contour: Ascending leap of a perfect 5th into the upper register, creating a large, anthemic arch shape across the phrase.)\n(Melody-Rhythm: Vocal lines are forcefully on the beat, driving and declarative, matching the full band's energy.)\n(Melody-Harmonic-Tension: Melody creates powerful tension by sustaining the 3rd (A) over the IV chord (D) for a full measure before resolving down, creating the hook's emotional pull.)\n(Inst: Full band crashes in. Layered acoustic guitars, powerful block-chord piano, heavy ride/crash cymbals.)\n(Vocal-Perf: Sudden shift to powerful chest belting, strained and raw. lush background vocal stacks add harmonic weight.)\n(Mix: Stereo image explodes in width; heavy parallel compression on drums and vocals for maximum impact.)\n(Chords: D - A - F#m - E)\nThis is a white knuckle summer, I am gripping the wheel\nEvery good thing I've been given I've got plans to conceal\nYou keep asking me what's underneath all this speed\nBut a man who runs this hard, darling, runs 'cause he needs\nI am made of the leaving, it's the only thing real\nThe only thing real\n\n[verse]\n(Inst: Arrangement drops back to verse 1 texture, but with lingering piano chords and subtle cymbal work.)\n(Vocal-Perf: Returns to the lower-intensity, confessional delivery, creating stark dynamic contrast with the preceding chorus.)\n(Chords: F#m - A - D - A)\nYou cooked for me on a Tuesday, I forgot how that felt\nSomebody waiting on me, cards already dealt\nI sat there at your table like a stranger in a church\nHands that don't know where to rest or what they're worth\nAnd I tried, I tried to let the stillness do its work\nBut by Thursday I was mapping every exit past the dirt road and the birch\n\n[chorus]\n(Melody-Harmonic-Tension: The tension on the IV chord is heightened by a more desperate vocal delivery, making the eventual resolution feel even more cathartic.)\n(Inst: Full band returns with even greater intensity. Ride cymbal is more prominent, driving the rhythm harder.)\n(Vocal-Perf: Maximum emotional strain, high notes are on the edge of breaking. Background vocals are higher in the mix.)\n(Chords: D - A - F#m - E)\nThis is a white knuckle summer, I am gripping the wheel\nEvery good thing I've been given I've got plans to conceal\nYou keep asking me what's underneath all this speed\nBut a man who runs this hard, darling, runs 'cause he needs\nI am made of the leaving, it's the only thing real\nThe only thing real\n\n[bridge]\n(Melody-Contour: Melody shifts to a descending contour, providing a moment of release and reflection.)\n(Melody-Harmonic-Tension: Phrases deliberately end on the 2nd (G#) over the V chord (E), creating an unresolved, hanging feeling that begs for the final chorus.)\n(Inst: Arrangement strips down to a lone acoustic guitar and a simple, sparse piano line.)\n(Vocal-Perf: Quieter, more vulnerable tone; a brief respite from the high-energy belting.)\n(Chords: D - A - E - F#m)\nMaybe staying is the braver kind of gone\nMaybe I've been running from the wanting all along\nGod I hope you don't wait up\n\n[outro]\n(Inst: Band swells one last time on the first line, then cuts out, leaving only the fading acoustic guitar and layered, repeating vocals.)\n(Vocal-Perf: Vocals become a mantra, layered and processed with a long reverb tail that fades to silence.)\nThis is a white knuckle summer, I am gripping the wheel\nEvery good thing I've been given I've got plans to conceal\nYou keep asking me what's underneath all this speed\nBut a man who runs this hard, darling, runs 'cause he needs\nI am made of the leaving, it's the only thing real\nI am made of the leaving, it's the only thing real\nI am made of the leaving",
  "cover_prompt": "生成一张无字音乐专辑封面。风格严格参照 20 世纪 Color Field Painting（色域绘画），如 Mark Rothko 晚期作品的色层叠压逻辑与 Helen Frankenthaler 的浸染法（soak-stain technique）。画面的核心色彩与情绪：深褪黄的琥珀色与铁锈红在画面中央形成灼热的宽幅色带，向上渗入一片荒凉的冷灰蓝，向下沉入几乎接近炭黑的深棕，整体传递出夏末公路尽头那种疲惫的、被什么灼烧过又被风干的身体感受。\n技法要求：色彩之间的过渡必须模拟颜料在未上浆的粗纹棉布（raw cotton canvas）上自然渗透、晕开的效果，边界柔软但保留颜料浓度不均匀造成的自然深浅变化（pigment pooling）。画面需要呈现真实画布的编织肌理（woven canvas texture），局部可见稀薄处透出的底布纹路。整体色调偏低饱和、微微发灰（muted, desaturated palette），避免荧光感和数字渐变的均匀平滑。\n绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、几何图案、锐利边缘、胶片颗粒滤镜、3D渲染质感。",
