  "prompt": "Genre: French Filter House / Nu-Disco; BPM: 126; Key: A# minor; Rhythm: A propulsive four-on-the-floor kick drum pattern provides the foundation, while a syncopated, melodic organic bassline and tight 16th-note hi-hats create an irresistible, funky groove with driving pocket syncopation.; Instruments: organic funk bass (warm, round tone); Nile Rodgers-style rhythm guitar (clean, muted chanks); 909-style drum machine (punchy kick, sharp clap); Rhodes piano (subtle harmonic pads); Filtered synth sweeps (transitional FX).; Vocals: Male tenor with a smooth, breathy, almost falsetto quality, delivering an intimate close-mic performance with generous reverb and delay.; Highlight: The moment the low-pass filter on the main instrumental sample fully opens for the first chorus, unleashing the crisp high-end of the funky guitar and hi-hats for the first time, creating a wave of euphoric release.",
  "title": "Glass Ceiling",
  "lyrics": "[intro]\n(Inst: Filtered sample loop, punchy kick, synth riser)\n(Chords: Bbm7 - Abm7 - Db7 - Gbmaj7)\n(Mix: Heavily filtered core loop, frequency focus 300-800Hz. Prominent sub-bass from kick. Sidechain compression pumps rhythmically. Wide stereo image with tight mono low-end.)\n\n[verse]\n(Inst: Filter sweep begins to open, hi-hats enter, bassline becomes clearer)\n(Vocal-Perf: Smooth, breathy tenor enters, effortless delivery, sits in reverb space)\n(Hook-DNA: Rhythmic motif is 'dotted-eighth + sixteenth' on first word, followed by a syncopated phrase that pushes into the next beat; melody anchors on root and 5th; repeats twice with lyrical variation)\n(Melody-Contour: Ascending arch shape per line, peaks on the final word, features a significant ascending major 6th leap for emphasis)\n(Melody-Rhythm: Vocal phrases consistently start on the 'and' of 4, creating anticipation for beat 1)\nYou walked in wearing borrowed gold\nA laugh that cracked the February cold\nI watched you from across the floor\nPretending I had seen that kind before\nBut something in the way you moved\nCut straight through everything I thought I knew\nLike pressure building under glass\nThe kind of tension built to last\nAnd I have never braced for something like this\n\n[chorus]\n(Inst: Full unfiltered sample loop, driving 16th-note hi-hats, prominent funk guitar)\n(Mix: Low-pass filter fully open, revealing full frequency spectrum. Sidechain compression effect is at its most intense. Perceived loudness increases significantly.)\n(Melody-Harmonic-Tension: The dominant (Db7) chord in the third bar of the loop creates strong harmonic tension, which is satisfyingly resolved by the tonic major (Gbmaj7) in the final bar, creating a cyclical, infectious feeling of release.)\n(Sound-Design: Iconic filter sweep opens completely on the downbeat of the section)\nThrough the glass ceiling, breaking through\nEvery wall I built comes down for you\nThrough the glass ceiling, out of control\nYou rewired something deep in my soul\nThrough the glass ceiling\n\n[interlude]\n(Inst: Sample loop is filtered down again, sometimes stripping back to just bass and drums. Guitar re-enters with a slow filter sweep up.)\n(Mix: Dynamic filtering creates a drop in energy, building anticipation for the next section.)\n\n[verse]\n(Inst: Filter opens again, but not as wide as the chorus. Layered clap on 2 and 4 adds punch.)\n(Vocal-Perf: Slightly more confident delivery, subtle ad-libs in the background)\nWe talked until the venue cleared\nYour voice the only frequency I heard\nYou said you never stay too long\nI said I never wrote a second song\nBut here I am rehearsing lines\nI never thought I'd need a second time\nLike pressure cracking open seams\nBetween my practiced life and buried dreams\nAnd I don't think I'm walking back from this\n\n[chorus]\n(Inst: Full unfiltered sample loop, driving 16th-note hi-hats, prominent funk guitar)\n(Mix: Peak energy. Filter wide open, sidechain pumping hard.)\n(Melody-Harmonic-Tension: The dominant (Db7) chord in the third bar of the loop creates strong harmonic tension, which is satisfyingly resolved by the tonic major (Gbmaj7) in the final bar, creating a cyclical, infectious feeling of release.)\nThrough the glass ceiling, breaking through\nEvery wall I built comes down for you\nThrough the glass ceiling, out of control\nYou rewired something deep in my soul\nThrough the glass ceiling\n\n[outro]\n(Inst: Elements are systematically filtered and faded out. The track deconstructs, leaving a filtered bassline and the kick drum.)\n(Vocal-Perf: A final, heavily reverberated vocal phrase might echo and fade.)\n(Mix: Slow low-pass filter sweep closes down over 8-16 bars, ending the track with a warm, muffled feel.)\nYou rewired something deep in my soul\nSomething deep in my soul\nDeep in my soul",
  "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：深夜俱乐部散场后残留的暖光晕染——深靛紫与铜金色在粗纹棉布上自然渗透交融，局部透出琥珀色的颜料积聚，仿佛一道隐形屏障正在被热度缓缓融穿，中心区域色层最薄，呈现几近透明的破口感，向四角逐渐沉厚。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。",
