  "prompt": "Genre: Mandopop / R&B Ballad; BPM: 144; Key: Bb Major; Rhythm: Half-time trap groove with syncopated kick/808, a sharp snare on 3, and intricate 16th/triplet hi-hats.; Instruments: Clean grand piano (arpeggios/chords), deep sub 808 bass, trap drum machine (punchy kick, sharp clap), and atmospheric background string pads for width.; Vocals: Female. Powerful, clear lead with a wide dynamic range from rhythmic rap-like delivery to a full-belted soaring chorus. Layered, emotive background harmonies.; Mood: The quiet hum of a refrigerator in an empty apartment, two hearts finally awakening at different moments, too late to reunite.; Production: High-fidelity, radio-ready polish. Wide stereo field, vocals upfront, deep clean low-end, emotive reverb.; Language: Mandarin; Highlight: The sudden melodic leap in the bridge, shifting from rhythmic speech to a high, vulnerable sung phrase that reveals personal pain after accusation.",
  "title": "错季",
  "lyrics": "[intro]\n(Chords: Ebmaj7 - F - Gm7 - Bb/D)\n(Inst: Sparse, atmospheric piano arpeggios create a melancholic mood. A soft synth pad swells underneath.)\n(Mix: Intimate and narrow, setting a reflective tone.)\n(Transition: Vocal enters cleanly on the downbeat of the chorus.)\n\n[chorus]\n(Chords: Ebmaj7 - F - Gm7 - Bb)\n(Vocal-Perf: Clear, emotive chest voice, sung with a sense of finality, mezzo-forte.)\n(Inst: Full modern trap beat enters abruptly; deep 808 bass, punchy kick, sharp clap on beat 3, and fast, rolling hi-hats. Piano continues its arpeggiated motif.)\n(Mix: Expands to a wide stereo field. Vocals are prominent and centered.)\n你在春天里终于看清了我\n我在秋雨里刚刚放下了你\n这场迟来的清醒隔着整段季节\n偏偏注定要错过彼此\n\n[verse]\n(Chords: Ebmaj7 - F - Gm7 - Bb)\n(Vocal-Perf: Shifts to a rhythmic, confident rap-like flow. Conversational and lower in the register, building in intensity.)\n(Inst: The beat maintains its groove, but the piano simplifies to a chordal backing, giving the vocal more space.)\n(Sound-Design: A subtle, rhythmic clock-ticking SFX is introduced, underlining the lyrical theme.)\n(Transition: Vocal melody rises at the end of the section, building anticipation for the chorus.)\n那年夏末的出租屋\n电风扇嗡嗡地转\n你把外套搭在椅背\n说留在这里陪我\n我以为这是开始\n却原来是你最后的温柔\n一个人在这段关系里撑伞\n另一个已经偷偷上了渡口\n你醒了 我还沉着\n我醒了 你已离座\n\n[chorus]\n(Chords: Ebmaj7 - F - Gm7 - Bb)\n(Vocal-Perf: More powerful and belted than the first chorus. Layered harmonies and ad-libs add emotional weight and texture.)\n(Inst: All elements return with greater intensity. Atmospheric string pads are more prominent in the mix, adding epic scale.)\n(Mix: The soundscape feels bigger and more saturated, reaching a dynamic peak.)\n(Transition: The beat and all instruments cut out suddenly on the final beat, leaving a single piano chord's reverb tail.)\n你在春天里终于看清了我\n我在秋雨里刚刚放下了你\n这场迟来的清醒隔着整段季节\n偏偏注定要错过彼此\n\n[bridge]\n(Chords: Ebmaj7 - Dm7 - Gm - Cm7 - Fsus4 - F)\n(Vocal-Perf: Begins intimately, almost spoken, then dramatically leaps into a high, pained, and vulnerable sung melody. Showcases extreme dynamic contrast and raw emotion.)\n(Inst: Stripped back to just sparse, emotive piano chords. The absence of the beat creates a moment of intense focus on the vocal.)\n(Mix: Close-mic'd vocal with a lush reverb tail, creating an intimate yet vast emotional space.)\n(Transition: A subtle synth riser and drum fill build energy into the final outro.)\n如果时间线上有一个路口\n我们曾经同时在场\n那我可不可以问你一句\n你是什么时候\n开始不爱了\n却没有告诉我\n\n[outro]\n(Chords: Ebmaj7 - F - Gm7 - Bb)\n(Vocal-Perf: A powerful, cathartic blend of soaring ad-libs and reflective spoken-word phrases, ending with a tender, almost whispered repetition of the clock motif.)\n(Inst: The full band and beat re-enter for a final, grand statement. The arrangement is dense and layered.)\n(Mix: The track reaches its widest and most epic point before a gradual fade, leaving only the sound of the piano and the clock ticking away.)\n两个人各自在不同的节气里悟透\n偏偏就是走不进同一个春秋\n我剪掉了那件外套的衬里\n才明白有些温度\n从来不是为我留\n你醒了 我还沉着\n我醒了 你已离座\n错季的人 终究错过",
  "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：两种截然不同的季节色调在同一画面中相遇又分离——左侧是沉静的春草绿与雾白交叠，右侧是褪色的赭黄与冷灰慢慢渗透，两种色域在画面中央隐约相触却不真正融合，仿佛两段时间轴彼此错位叠放。\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。",
