  "prompt": "Genre: Alternative Rock, Arena Rock, Piano Rock; BPM: 139; Key: Eb Major; Rhythm: Starts with a slow, half-time ballad feel (70 BPM) on organ/piano, builds to a driving, straight-eighth rock groove with a powerful backbeat; Instruments: Vintage pump organ, air movement; Soft felt grand piano, hammer noise; Distorted lead guitar, long delay trails; Round P-bass tone, root notes; Live arena rock kit; Vocals: Male, starting with an intimate close-mic breathy falsetto, building to a strained, passionate full-chest voice with lush background vocal stacks; Mood: Cosmic dust spins with quiet love—in hospitals, in heartbreak, your presence anchors everything that briefly glows.; Highlight: The single, unified kick drum and bass note that lands under the first core promise in the chorus, transforming the song from a quiet prayer into an anthemic declaration.",
  "title": "尘埃有重量",
  "lyrics": "[intro]\n(Inst: Vintage pump organ, sustained chords; Soft felt grand piano, simple repeating melody)\n(Mix: Mix is centered, narrow stereo field. High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Prominent low-mids from organ, clear piano attack. Heavy plate reverb with long decay, creating a cavernous, sacred space.)\n\n[verse]\n(Chords: Eb - Gm - Cm - Ab)\n(Melody-Contour: High falsetto, mostly stepwise motion, small arch shape per phrase.)\n(Melody-Rhythm: Phrases begin on beat 1, very legato, long sustained notes.)\n(Inst: Vintage pump organ, sustained chords; Soft felt grand piano, simple repeating melody.)\n(Vocal-Perf: Intimate close-mic falsetto, extremely breathy, audible mouth sounds.)\n有人在手术室外坐到天亮\n走廊灯把影子拉成一条长线\n他们哭过 也咬着牙撑过\n所有重量都压在这颗星球上\n\n[verse]\n(Chords: Eb - Gm - Cm - Ab)\n(Inst: Adds clean electric guitar, arpeggiating chords, light chorus effect.)\n(Vocal-Perf: Still breathy falsetto, slight increase in volume.)\n从轨道上看不见那条走廊\n只是一粒尘埃在黑暗里发光\n爱与失去都藏进地壳的褶皱\n小得像什么都没发生过一样\n\n[chorus]\n(Chords: Ab - Eb - Bb - Bb)\n(Hook-DNA: Core motif is "我会是你的磐石"; Rhythmic pattern is long-long-long-short-short; Anchors on the root note on "石"; Repetition is declarative, a single statement of intent.)\n(Melody-Contour: Ascending leap of a P4 on "穿过" creates lift.)\n(Melody-Rhythm: Vocal lines start on beat 1, holding notes across bar lines.)\n(Melody-Harmonic-Tension: Melody on "漫长" holds the 4th over the V chord, creating suspension before resolving down.)\n(Inst: Adds round P-bass on root notes, simple kick-snare drum pattern.)\n(Vocal-Perf: Shifts from falsetto to a soft, supported full voice.)\n(Mix: Stereo field widens slightly.)\n但我知道你在这里\n在这颗细小的尘埃上\n呼吸过 痛过 爱过我\n这就是全部宇宙\n\n[verse]\n(Chords: Eb - Gm - Cm - Ab)\n(Inst: Drums become more assertive, hi-hat enters with straight 8ths. Bass is more prominent.)\n(Vocal-Perf: Full chest voice, no longer falsetto, building intensity.)\n有人翻遍旧照片找一张笑脸\n发现自己已经忘了他的声音\n多少生离在这片土地上积累\n全部真实 全部无处安放\n\n[chorus]\n(Chords: Ab - Eb - Bb - Bb)\n(Hook-DNA: Core motif is "我会是你的磐石"; Rhythmic pattern is long-long-long-short-short; Anchors on the root note on "石"; Repetition is declarative, a single statement of intent.)\n(Melody-Contour: Ascending leap of a P4 on "穿过".)\n(Melody-Rhythm: Vocal lines start on beat 1, holding notes across bar lines.)\n(Melody-Harmonic-Tension: Melody on "漫长" holds the 4th over the V chord, creating suspension before resolving down.)\n(Inst: Full band enters. Crashing cymbals, driving bass, prominent piano chords.)\n(Vocal-Perf: Passionate, full-chest belt. Lush background vocal stacks enter.)\n(Mix: Stereo field explodes to maximum width. Parallel compression on drums for punch.)\n但我知道你在这里\n在这颗细小的尘埃上\n呼吸过 痛过 爱过我\n这就是全部宇宙\n\n[interlude]\n(Chords: Ab - Eb - Bb - Bb)\n(Inst: Distorted lead guitar takes the melody, drenched in delay and reverb. Full band provides massive backing.)\n(Sound-Design: Guitar feedback swells into the transition.)\n\n[bridge]\n(Chords: Ab - Eb - Bb - Bb)\n(Melody-Harmonic-Tension: Vocal ad-libs and background vocals create layers of suspension and release, with the lead vocal often soaring on the 5th and root over the chords, creating a feeling of catharsis.)\n(Inst: Band drops back slightly to a pulsing rhythm. Piano and organ are more prominent again.)\n(Vocal-Perf: Strained, emotional ad-libs and layered vocals.)\n从几亿光年外看过来\n什么都消失了\n只剩一粒光\n而你就是那粒光里\n我唯一认得出的温度\n\n[outro]\n(Chords: Ab - Eb - Bb - Bb)\n(Inst: Full band continues, with the lead guitar melody weaving around the vocals. String section swells.)\n(Vocal-Perf: Repeated phrase with layered harmonies, fading out.)\n你在这里\n在这颗尘埃上\n爱过我\n这就是全部宇宙",
  "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：深邃的宇宙蓝黑渐变为中心一点极淡的暖白光晕，如同从绝对虚空中凝视一粒发光的尘埃——周遭是无边的冷寂深蓝与炭灰，中心光点晕散出微弱的琥珀暖意，两种色域之间存在极度柔软却浓度不均的过渡地带。\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。",
