  "prompt": "Genre: Piano-driven Arena Rock Ballad; BPM: 70; Key: Eb Major; Rhythm: Sparse, half-time feel, initially defined by sustained organ and quarter-note piano pulses, building to a steady, powerful 4/4 rock backbeat (kick on 1 & 3, snare on 2 & 4).; Instruments: Pump organ, sustained chords; Upright piano, close-mic'd; Clean arpeggiated e-guitar; Distorted lead e-guitar; Round-wound bass, roots; Acoustic kit, large room reverb; Orchestral strings; Vocals: Male, shifting from breathy falsetto (intimate close-mic) to soaring, emotive chest voice.; Mood: The quiet hum of a hospital waiting room at 3 AM, holding a cold cup of coffee, waiting for news.; Highlight: The sudden, explosive entry of the full drum kit and distorted lead guitar after the quiet second chorus, marking a massive stadium drop from ballad to anthem in one beat.",
  "title": "沙粒星球",
  "lyrics": "[intro]\n(Inst: Pump organ, sustained chords, prominent air noise)\n(Chords: Eb - Gm/D - Cm - Bb)\n(Mix: Centered mono image, narrow field. Low-pass filter on organ. Dark, intimate. Expensive analogue warmth, silky high-end.)\n\n[verse]\n(Inst: Upright piano enters, simple quarter notes. Organ continues.)\n(Vocal-Perf: Breathy, delicate falsetto. Very close-mic'd.)\n(Melody-Contour: Descending stepwise motion, small melodic range.)\n(Melody-Rhythm: Phrases start on beat 1, very legato, long sustained notes.)\n(Chords: Eb - Gm/D - Cm - Bb | Ab - Eb - Bb - Eb)\n(Mix: Piano slightly panned left. Vocal dead center.)\n父亲的背在某个秋天开始弯\n我站在客厅看他拖着脚走向厨房\n那双手曾举起过我整个少年时代\n如今连药瓶都拧不开\n我在外地接到电话的那个傍晚\n窗外的工地还在轰鸣，心却空了半边\n挂断后没有哭，只是站着站着\n忘记了身在何处\n\n[chorus]\n(Inst: Acoustic guitar strums softly. Bass enters, root notes. Clean electric guitar arpeggios.)\n(Vocal-Perf: Shifts to chest voice, more open, stronger dynamics. Lush background vocal stacks enter subtly.)\n(Hook-DNA: Core motif is \"guide you home\", rhythmic pattern is two quarter notes followed by a half note; pitch resolves down to the tonic; motif repeats, then rises for \"ignite your bones\".)\n(Melody-Contour: Arch shape, features an ascending major 6th leap on \"guide you\".)\n(Melody-Rhythm: Straight quarter notes, on the beat, simple and anthemic.)\n(Melody-Harmonic-Tension: Melody lands on the 5th (Bb) over the IV chord (Ab), creating a gentle, hopeful tension before resolving to the root on the I chord (Eb).)\n(Chords: Ab - Eb - Bb - Eb)\n(Mix: Stereo image widens slightly.)\n这颗星球太小装不下所有的亏欠\n我只是想在你还认得我的时候\n把那些没说出口的都还给你\n\n[verse]\n(Inst: Piano, organ, bass continue.)\n(Vocal-Perf: Returns to softer falsetto, but with more presence than first verse.)\n(Melody-Contour: Similar descending shape to first verse.)\n(Melody-Rhythm: Same legato, on-beat phrasing.)\n(Chords: Eb - Gm/D - Cm - Bb | Ab - Eb - Bb - Eb)\n小时候你说宇宙大得没有边界\n我怕黑，你就把手电筒给了我\n现在轮到我坐在走廊的折叠椅上\n替你怕那些我不懂名字的黑暗\n\n[chorus]\n(Inst: Full band enters explosively after this section. Drums start a simple beat here.)\n(Vocal-Perf: Full power chest voice, emotional strain audible.)\n(Hook-DNA: Core motif is \"guide you home\", rhythmic pattern is two quarter notes followed by a half note; pitch resolves down to the tonic; motif repeats, then rises for \"ignite your bones\".)\n(Melody-Contour: Arch shape, prominent ascending major 6th leap.)\n(Melody-Rhythm: Straight quarter notes, driving the build.)\n(Melody-Harmonic-Tension: Tension on the IV chord is more pronounced due to increased dynamics and added instrumentation before the final resolution.)\n(Chords: Ab - Eb - Bb - Eb)\n(Mix: Builds in width and volume, preparing for the drop.)\n这颗星球太小装不下所有的亏欠\n我只是想在你还认得我的时候\n把那些没说出口的都还给你\n\n[interlude]\n(Inst: Heavily distorted lead guitar, soaring melody. Full stadium drums, powerful snare. Bass driving. Organ pads full spectrum.)\n(Mix: Explosive, wide stereo image. Heavy parallel compression on drums. Guitars panned wide. Sub-bass present.)\n(Chords: Ab - Eb - Bb - Eb)\n\n[bridge]\n(Inst: Band pulls back slightly. Drums simpler, kick and cymbal washes. Bass and organ hold foundation.)\n(Vocal-Perf: Layered gang vocals, anthemic and pleading. Main vocal is powerful, high in the register.)\n(Melody-Harmonic-Tension: Melody phrases end on the 3rd or 5th, creating a feeling of communal pleading that doesn't fully resolve until the final outro chorus. The repetition builds tension through persistence.)\n(Chords: Ab - Eb - Bb - Eb)\n你叫过我的乳名\n那声音从某一天起再没响过\n你叫过我的乳名\n而我\n你叫过我的乳名\n我终于明白那是你给我留的灯\n你叫过我的乳名\n而我\n\n[outro]\n(Inst: Full band, soaring guitars, strings swelling.)\n(Vocal-Perf: Final powerful vocal delivery, holding long notes.)\n(Mix: Maximum width and dynamic intensity, slow fade out.)\n(Chords: Ab - Eb - Bb - Eb)\n这颗星球太小装不下所有的亏欠\n我只是想在你还认得我的时候\n把那些没说出口的都还给你",
  "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：深沉的炭灰与锈褐色在画面下方沉积，向上缓缓渗透为一片暗金琥珀，最终在顶端稀薄化为近乎透明的米白，整体散发出一种沉默而庄重的温度，像旧棉布在灯下被岁月浸染的颜色。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。",
