  "lyrics": "[intro]\n(Chords: F# - C# - D#m7 - Badd9)\n(Mix: Centered, intimate field)\n(Inst: Clean electric guitar arpeggios, single notes, light delay. Acoustic guitar enters with gentle strumming.)\n(Vocal-Perf: Breathy, wordless \"Mmm\" melody.)\n\n[verse]\n(Chords: F# - C# - D#m7 - Badd9)\n(Vocal-Perf: Soft, conversational chest voice; mezzo-piano; clear diction.)\n(Inst: Bass guitar enters, playing root notes. Drums enter with a simple kick and closed hi-hat pattern.)\n(Melody-Contour: Mostly descending, reflective.)\n(Transition: Ride cymbal swell.)\n你递过来一杯水的温度\n刚好让人说不出拒绝\n我喝下去 胸口发烫\n以为那是爱 原来是习惯了渴\n\n[pre-chorus]\n(Chords: Badd9 - C# - F# - C#/F)\n(Vocal-Perf: Dynamics build to mezzo-forte; more sustained notes.)\n(Inst: Full drum kit enters with snare on 2 and 4. Bass becomes more active.)\n(Melody-Rhythm: More flowing and lyrical.)\n(Transition: Drum fill.)\n最体面的离开是没有离开\n只是把距离拉到刚好\n我们还能互道晚安\n又各自失眠到天亮\n\n[chorus]\n(Chords: F# - C# - D#m7 - Badd9)\n(Vocal-Perf: Strong, open-throated chest voice; forte; emotional emphasis.)\n(Inst: Overdriven electric guitar enters with sustained power chords, creating a wall of sound. Subtle string pads add width.)\n(Mix: Expands to full stereo width; vocals sit powerfully above the instrumentation.)\n(Melody-Contour: Ascending, anthemic lift.)\n钝刀割的是慢慢疼\n不见血才叫人撑着不走\n你把犹豫喂给我当晚餐\n我嚼碎了 还替你说好吃\n这不叫情深\n这叫我一个人爱得太用力\n才把你的将就\n看成了专一\n\n[interlude]\n(Chords: F# - C# - D#m7 - Badd9)\n(Inst: Lead electric guitar solo, melodic and distorted with long sustained notes and vibrato. Rhythm section is driving and tight.)\n(Mix: Guitar solo is front and center.)\n(Vocal-Perf: Distant, emotive vocal ad-libs float under the solo.)\n(Transition: Solo ends on a sustained note, feedback fades.)\n\n[bridge]\n(Chords: B - F# - C# - D#m7)\n(Inst: Instrumentation drops back, cleaner guitar tone, focus on arpeggios.)\n(Vocal-Perf: Airy, semi-improvised ad-libs.)\n(Mix: Dynamic drop, creates a moment of quiet reflection.)\n(Transition: Snare drum roll builds back into the chorus.)\n我不是不明白\n只是明白得太贵\n用两年的时间\n买了一个字的答案\n\n[chorus]\n(Chords: F# - C# - D#m7 - Badd9)\n(Vocal-Perf: Maximum emotional intensity; powerful ad-libs over the main vocal.)\n(Inst: All instruments at full power. Guitar solo motifs are layered in the background.)\n(Mix: Song's climax, dense and wide.)\n(Melody-Dev: Vocalist adds slight variations and embellishments.)\n钝刀割的是慢慢疼\n不见血才叫人撑着不走\n你把犹豫喂给我当晚餐\n我嚼碎了 还替你说好吃\n这不叫情深\n这叫我一个人爱得太用力\n才把你的将就\n看成了专一\n\n[outro]\n(Chords: F# - C# - D#m7 - Badd9)\n(Inst: Instruments fade out, leaving the arpeggiated clean electric guitar and a final melodic phrase from the lead guitar.)\n(Mix: Slow fade to silence.)\n(Structure: Fade out.)\n现在终于懂了\n疼是真实的\n你不是",
  "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：深锈红与暗褐色在画布中央缓慢渗透彼此，边缘向外晕散成灰紫与脏白，整体像一道未愈合的钝伤压在胸腔里，沉而不鲜，带着闷热的体温感，没有爆发只有持续的重量。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。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。",
