  "prompt": "Genre: J-Pop / Trance / Anisong; BPM: 143; Key: Cm / Eb Major; Rhythm: Driving beat with a constant kick, sharp snare on 2/4, and a fast, pumping 16th-note synth bass line.; Instruments: Punchy electronic drums, layered trance-gate synth bass, distorted rhythm guitar, and bright supersaw synth leads, pads, and fast arpeggios.; Vocals: Female, high-pitched, clear, and powerful lead vocal with a pure tone and energetic delivery. Polished with light, transparent pitch correction.; Mood: The final moments of a power-up sequence, energy crackling in the air as city lights blur into streaks below.; Production: Dense, high-fidelity mix with a wide stereo image. Bright vocals upfront, heavy sidechain for a pumping feel.; Language: Chinese; Highlight: The split-second of silence after the massive synth riser and drum fill, right before the first chorus erupts.",

  "lyrics": "[intro]\n(Chords: Cm - Gm - Ab - Eb - Bb/D - Cm - G - Cm)\n(Inst: High-energy opening with fast synth arpeggios, a catchy supersaw lead melody, and full driving drum beat. Establishes the core trance feel immediately.)\n(Mix: Wide stereo field, synths panned hard, rhythm section centered and powerful.)\n\n[verse]\n(Chords: Cm - Ab - Eb - Bb - Cm - Ab - Eb - G)\n(Vocal-Perf: Controlled and rhythmic delivery, lower in register than the chorus, mezzo-piano dynamic.)\n(Inst: Energy drops slightly. Kick and pumping synth bass drive the section. Main synths switch to background pads and subtle plucks.)\n(Transition: A subtle synth riser begins to build at the end of the section.)\n指尖扫过那条断裂的弦\n震频还残留在掌心里\n像某种被压缩进骨骼深处的\n将要引爆的信号\n\n[pre-chorus]\n(Chords: Ab - Eb - Bb - Gm - Ab - Eb - F - Gsus4 - G)\n(Vocal-Perf: Melody ascends, building tension and intensity towards mezzo-forte.)\n(Inst: Pads swell, snare drum builds into a rapid fill. Energy ramps up significantly.)\n(Sound-Design: Prominent synth riser and filter sweep creating a powerful lift.)\n裂缝正在扩张\n共鸣腔里有什么在燃烧\n\n[chorus]\n(Chords: Cm - Gm - Ab - Eb - Bb/D - Cm - G - Cm)\n(Vocal-Perf: Full power, soaring high notes, sustained and confident delivery at forte.)\n(Inst: Explosive energy. Full layers of supersaw synths, distorted rhythm guitar power chords enter, driving beat at maximum intensity.)\n(Mix: Extremely dense and wide. Vocals sit on top but are surrounded by walls of synths.)\n所有频率向我涌来\n穿透皮肤 穿透骨缝\n这世界的噪声都被我反射\n变成共振——变成光\n我听见自己在震鸣\n不是回声 是我本来的声音\n散裂之前的那一刻\n才是我最锋利的形状\n\n[verse]\n(Chords: Cm - Ab - Eb - Bb - Cm - Ab - Eb - G)\n(Vocal-Perf: Returns to a more controlled, rhythmic delivery. Clear enunciation.)\n(Inst: Similar arrangement to the first verse, but with an added counter-melody from a pluck synth.)\n(Transition: A quick drum fill leads into the pre-chorus build.)\n曾经以为调低音量\n就能让自己不那么显眼\n结果沉默堆积成了共鸣箱\n每一次压制都在放大\n\n[chorus]\n(Chords: Cm - Gm - Ab - Eb - Bb/D - Cm - G - Cm)\n(Vocal-Perf: Full power again, with added subtle background harmonies to increase impact.)\n(Inst: Maximum energy, all elements firing. Distorted guitar is slightly more prominent in the mix.)\n(Mix: Saturated and powerful, maintaining the epic scale.)\n所有频率向我涌来\n不再躲避 不再消减\n把那些逼迫我沉默的压强\n全部转化——全部燃\n我就是这场震鸣\n不需要谁来给我定义\n临界点之后的爆发\n才是我真正的名字\n\n[interlude]\n(Chords: Cm - Gm - Ab - Eb - Bb - Cm - G - Cm)\n(Inst: Instrumental section featuring a highly melodic and technical distorted electric guitar solo. The solo uses fast runs, string bends, and a wah effect. The underlying rhythm section remains high-energy with driving drums and pumping bass.)\n(Mix: Guitar is the clear focus, front and center with dedicated reverb and delay.)\n\n[outro]\n(Chords: Ab - Eb - Bb - Cm - Gsus4 - G - Cm)\n(Inst: Music gradually deconstructs. The main synth lead plays the hook one last time as drums fade out, ending on a sustained synth pad chord with a long reverb tail.)\n(Vocal-Perf: A final, distant vocal ad-lib might echo out.)\n(Structure: Long fade out.)",
  "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：深紫蓝与高压电弧白之间的剧烈张力渐变——底层是浓重的靛蓝与钴紫叠压，中部涌出一道被颜料浓度不均匀撕开的近白色裂带，如同物质在临界状态下被强行震裂的截面，顶部收束为暗沉的炭灰，整体传达出压缩到极限、即将共振爆发前一瞬的物理张力感。\n\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\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。",
