  "prompt": "Genre: Mandopop / R&B Ballad; BPM: 140; Key: Eb Major; Rhythm: Relaxed half-time groove with a gentle backbeat on sidestick snare, sparse kick drum, and soft 16th-note hi-hats; Instruments: Nylon string guitar (main arpeggios), clean electric guitar (melodic fills), warm fretless-style bass, soft live drum kit (sidestick), and lush orchestral strings; Vocals: Male tenor, clear and smooth with a conversational delivery. Intimate and present, with clean reverb and subtle breathiness; Mood: Finding an old mixtape in a dusty box on a rainy afternoon, the quiet hum of the past filling the room; Production: High-fidelity studio polish with analogue warmth. Wide, natural stereo image. Vocals are centered and intimate. Smooth compression and lush reverb tails; Language: Mandarin; Highlight: The sudden shift from singing to a rhythmic spoken-word bridge, where the vocal timbre changes completely, delivering the core metaphor over the established gentle groove.",

  "lyrics": "[intro]\n(Chords: Eb - Ab - Eb - Bb)\n(Inst: Nylon string guitar plays a gentle, arpeggiated motif. A high, delicate bell sound accents the melody. Intimate and nostalgic feel.)\n(Vocal-Perf: Instrumental)\n(Mix: Narrow stereo field, focused on the guitar.)\n\n[verse]\n(Chords: Eb - Bb/D - Cm - Gm - Ab - Eb/G - Fm - Bb)\n(Inst: Bass enters with a smooth, melodic line. Soft drum kit with sidestick snare provides a gentle backbeat. Nylon guitar continues.)\n(Vocal-Perf: Conversational and soft chest voice, mezzo-piano dynamic. Clear, upfront delivery.)\n(Mix: Vocals centered, instruments creating a warm, intimate space around them.)\n你习惯把窗帘拉到三分之一\n留那一道光斜进来\n我睡在你靠墙那侧太久\n忘了自己的肩膀原来朝哪摆\n\n[pre-chorus]\n(Chords: Ab - Bb - Gm - Cm - Ab - Bb)\n(Inst: Subtle electric guitar swells appear. Bass becomes more active, leading into the chorus. A slight dynamic build.)\n(Vocal-Perf: Melody ascends slightly, building tension. Tone remains gentle but with more intent.)\n(Transition: Drums play a simple fill on the last beat.)\n后来一个人睡 总侧向那一边\n压着空了的右半\n身体记得你的位置\n但找不到你的体温来填\n\n[chorus]\n(Chords: Ab - Bb - Gm - Cm - Ab - Bb - Eb)\n(Inst: Lush orchestral strings enter, providing a wide, emotional pad. Drums become slightly more defined, but still gentle. The full arrangement is present.)\n(Vocal-Perf: Mezzo-forte dynamic, more sustained notes and controlled vibrato. Voice feels more open and emotive.)\n(Mix: Stereo field widens significantly with the strings. Vocals sit comfortably in the full mix.)\n分开了这么久 我还是睡那一侧\n像在等一个不会再发生的翻身\n这不叫想念 叫没学会\n一个人怎么把自己放平\n怎么把自己放平\n\n[verse 2]\n(Chords: Eb - Bb/D - Cm - Gm - Ab - Bb)\n(Inst: Arrangement pulls back slightly, similar to the first verse/pre-chorus but with lingering string textures.)\n(Vocal-Perf: Returns to a more conversational, intimate delivery, contrasting with the previous chorus.)\n你走的那个早晨我没有送\n只是坐在床沿发了很久的呆\n闹钟还设在你起床的点\n响了我才意识到 那个人不在\n是否该把右边的枕头收起来\n收起来就真的明白\n\n[bridge]\n(Chords: Ab - Bb - Gm - Cm)\n(Inst: Strings become more rhythmic, playing pizzicato or short stabs. Drums and bass provide a steady, minimal groove. Nylon guitar is sparse.)\n(Vocal-Perf: A sudden shift to rhythmic spoken-word, almost a gentle rap. Tone is narrative and direct, a stark contrast to the melodic singing.)\n(Mix: Vocals are dry and upfront, emphasizing the textural shift.)\n有人说分手之后要重新布置房间\n换掉床单换掉方向换掉一切痕迹\n但肌肉不听那套 它只记得惯性\n我换了床 却还是睡向同一个方向\n有些失去是写进姿势里的\n睁开眼睛才知道自己还没走出去\n\n[chorus]\n(Chords: Ab - Bb - Gm - Cm - Ab - Bb - Eb)\n(Inst: The fullest and most dynamic arrangement. Strings swell with soaring counter-melodies. Electric guitar adds more prominent fills. Drums are at their most present.)\n(Vocal-Perf: The most powerful and emotional delivery, forte dynamic. Sustained high notes with expressive vibrato.)\n(Mix: Maximum width and depth. The emotional climax of the song.)\n分开了这么久 我还是睡那一侧\n像在等一个不会再发生的翻身\n这不叫想念 叫没学会\n一个人怎么把自己放平\n怎么把自己放平\n\n[outro]\n(Chords: Eb - Ab - Eb - Bb - Eb)\n(Inst: Instruments fade out one by one, leaving the nylon string guitar and fading strings. The opening bell motif returns.)\n(Vocal-Perf: Instrumental)\n(Mix: A slow fade to silence, leaving the reverb tail of the final string chord.)\n(Transition: Decrescendo to silence.)",
  "cover_prompt": "生成一张无字音乐专辑封面。风格参照日本\"もの派\"（Mono-ha）的物质感与李禹焕（Lee Ufan）绘画中\"留白与一笔\"的克制美学，结合湿拓画（Ebru / paper marbling）的有机纹理。画面核心：一道极细的晨光楔形，从画面左上角斜向切入大面积的灰蓝留白，光带边缘在湿润纸面上自然洇散，颜色从暖白过渡到冷灰，像被压实的被褥在低光中呈现出的织物起伏——没有人，没有轮廓，只有光落下来的那个角度，和它打不到的那片阴影。\n技法要求：几何图形的边缘必须是颜料在湿润纸面上自然扩散形成的（ink bleeding on wet paper），而非数字绘制的精准轮廓。背景需要呈现真实手工纸的纤维质感（visible paper fibers, deckled edges texture），可以带有轻微的水渍痕迹（watermark stains）和纸张泛黄的老化感。构图极度克制，大面积留白，主体偏离中心（off-center composition）。整体像一张被扫描的实体版画作品（scanned fine art print），而非数字生成图像。\n绝对禁止：任何文字/字母/拼音、人物或人物轮廓、复杂场景、风景照片感、3D渲染、塑料质感的光泽。",
