  "prompt": "Genre: Neo-Soul, R&B, Gospel-influenced; BPM: 96; Key: E minor; Rhythm: Slow, heavy 12/8 shuffle groove with a strong, laid-back backbeat and triplet-feel piano arpeggios creating a dragging, soulful pocket.; Instruments: Acoustic Piano (close-mic'd, resonant, brain-scratching melodic hook), Acoustic Drum Kit (deep kick, subtle hats); Vocals: Female, soulful, wide dynamic range from intimate vocal fry to powerful chest belting, frequent use of melismatic runs.; Mood: A heated argument that ends in a passionate embrace, still tasting the salt from tears on their lips.; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Dynamic, organic mix with a prominent central vocal and wide stereo harmonies.; Highlight: The moment the first chorus hits and the lush background vocal stacks bloom from nowhere, instantly widening the stereo field and transforming a solo confession into a sweeping, gospel-tinged declaration.",

  "lyrics": "[intro]\n(Mix: Wide stereo field. Vocals dry and centered. Piano slightly to the right. Drums centered, natural room reverb. Bass centered. Analogue warmth, smooth highs, dynamic range preserved.)\n(Inst: Female lead, unaccompanied)\n(Vocal-Perf: Intimate, breathy, melismatic, quiet soulful runs)\n(Melody-Contour: Descending line, circling around the 5th and 3rd, ending on the tonic.)\n(Melody-Rhythm: Freeform, rubato feel, not locked to a strict tempo.)\nEvery room we wreck becomes a place I'm coming home to\n\n[verse]\n(Transition: Piano arpeggio enters, establishing tempo)\n(Chords: Em - Bm/D - Cmaj7 - B7)\n(Inst: Acoustic Piano playing arpeggiated riff, sparse kick/snare)\n(Vocal-Perf: Rhythmic but conversational, building intensity, adds slight rasp)\n(Melody-Contour: Mostly stepwise motion within a narrow range, short phrases)\n(Melody-Rhythm: Phrases start on the upbeat, syncopated against the piano, leaving space)\nYou burn so cold\nI melt beside the door\nYou throw your words like gravel\nI keep asking more\nSomething in your silence\nI have never felt before\n\n[chorus]\n(Hook-DNA: Rhythmic motif is \"long-long-short-long\" (Fall-in' in and out); Anchors on the root note 'E'; Motif repeats with slight melodic variation.)\n(Melody-Contour: Ascending leap of a P4 to the peak note on \"fallin'\", then descending.)\n(Melody-Rhythm: Main phrase lands squarely on beat 1, strong and declarative.)\n(Melody-Harmonic-Tension: Holds the 7th (D) over the Em chord for tension before resolving down to the G on the Cmaj7 chord, creating a feeling of release.)\n(Chords: Am7 - Gmaj7 - Cmaj7 - B7)\n(Mix: Stereo widens significantly, background vocals fill the space.)\n(Inst: Lush gospel BGVs enter, full drum kit, subtle bass)\n(Vocal-Perf: Shifts to powerful chest voice, more sustained notes)\nI taste the salt on your skin, I breathe the smoke in your hair\nAnd I keep staying where I swore I'd never dare\n\n[verse 2]\n(Chords: Em - Bm/D - Cmaj7 - B7)\n(Mix: Narrows back down, BGVs drop out)\n(Inst: Piano and drums, bass more prominent)\n(Vocal-Perf: Dynamic contrast, starts softer and builds back up, more ad-libs)\n(Melody-Contour: More complex melismatic runs, wider range than verse 1)\n(Melody-Rhythm: More rhythmically dense phrasing, less space between lines)\nOh, what a mess we made of Sunday morning\nYou left a bruise of blue just below my collarbone\nAnd still I pressed my cheek against that same warm shoulder\nLike the wreckage was the only place I've ever known\n\n[chorus]\n(Hook-DNA: Rhythmic motif is \"long-long-short-long\" (Fall-in' in and out); Anchors on the root note 'E'; Motif repeats, lead vocal adds intense ad-libs over the top.)\n(Melody-Contour: Ascending leap of a P4 to the peak note on \"fallin'\", then descending.)\n(Melody-Rhythm: Main phrase lands squarely on beat 1, strong and declarative.)\n(Melody-Harmonic-Tension: Holds the 7th (D) over the Em chord for tension before resolving down to the G on the Cmaj7 chord, creating a feeling of release.)\n(Chords: Am7 - Gmaj7 - Cmaj7 - B7)\n(Mix: Widest point, strings enter subtly.)\n(Inst: Full ensemble, strings add sustained pads underneath)\n(Vocal-Perf: Full power, belting, emotional ad-libs, layered with BGVs)\nI taste the salt on your skin, I breathe the smoke in your hair\nAnd I keep staying where I swore I'd never dare\n\n[bridge]\n(Chords: Static Am7 - Gmaj7 progression)\n(Inst: Piano, drums, BGVs become the main focus)\n(Vocal-Perf: Lead vocal shifts to ad-libs and calls, interacting with the BGV choir)\n(Melody-Harmonic-Tension: The entire section functions as a harmonic vamp, building tension by repetition without resolving to the tonic, creating anticipation for the final chorus.)\n(Melody-Contour: BGV harmonies stack and build, lead vocal improvises runs over the top)\nStay, oh stay\nEven when the fever breaks\n\n[outro]\n(Chords: Am7 - Gmaj7 - Cmaj7 - B7)\n(Inst: Instruments start to fade, piano riff continues)\n(Vocal-Perf: Vocals become more freeform, ad-libbing, fading out with emotion)\n(Mix: Slow fade out, leaving piano and vocal reverb tail.)\nI taste the salt, I breathe the smoke\nAnd I'm still here, I'm still here\nSalt and smoke, salt and smoke\nAnd I keep staying, I keep staying, yeah",
  "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：深沉的炭灰色与锈红色交叠，底部渗出一道隐约的琥珀暖光，仿佛烟雾中残存的余烬——沉重、灼热、却带着无法割舍的柔情。\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。",
