  "prompt": "Genre: Mandopop / Ballad; BPM: 155; Key: G Major; Rhythm: Slow 4/4 ballad groove. Acoustic guitar arpeggios drive the 16th-note feel. Drums play a sparse backbeat on 2 & 4.; Instruments: Acoustic Guitar (steel-string, intricate arpeggios); Piano (soft, supportive chords); Bass (clean, round); Drums (natural kit, simple backbeat); Strings (warm pads).; Vocals: Male tenor, clear and breathy. Sincere delivery with a mix of gentle chest voice and controlled falsetto. Light reverb and compression.; Mood: Looking at a faded photograph in a quiet attic, the scent of old paper and dust in the air.; Production: High-fidelity, radio-ready polish. Vocals are upfront and centered in a wide stereo field. Lush reverb creates an intimate space.; Language: Mandarin; Highlight: The downbeat of the first chorus, as the vocal melody leaps upward into an emotionally raw timbre while a warm string pad swells underneath for the first time.",

  "lyrics": "[intro]\n(Chords: G - D/F# - Em7 - Cmaj7)\n(Inst: Intricate fingerpicked acoustic guitar motif establishes the main theme.)\n(Mix: Centered, dry, intimate.)\n(Hook-DNA: The arpeggiated G-D/F#-Em7-Cmaj7 progression carries the song's core emotion.)\n\n[verse]\n(Chords: Cmaj7 - G/B - Am7 - Dsus4 - D)\n(Vocal-Perf: Soft, breathy, conversational mezzo-piano.)\n(Inst: Solo acoustic guitar provides the only accompaniment, creating a sparse, personal atmosphere.)\n(Mix: Vocals are upfront, very little reverb, feels close to the listener.)\n(Transition: A single, sustained piano chord swells gently into the chorus.)\n衣柜角落塞着一件旧毛衣\n洗了七次 还是她的气息\n袖口磨破的地方 是她惯用左手\n早就该扔 却没有\n\n[chorus]\n(Chords: G - D/F# - Em7 - Cmaj7)\n(Vocal-Perf: Dynamic lift to mezzo-forte, more sustained notes, emotional strain on the upper register.)\n(Inst: Bass, simple drums with brushes, and soft string pads enter, adding warmth and width.)\n(Mix: Stereo field widens significantly. Vocal reverb increases, creating a sense of space and reflection.)\n(Sound-Design: The entrance of the full band on the downbeat provides the song's primary emotional release.)\n她不需要我 我也知道她不需要\n却把那毛衣压在冬天最深的角落里\n用这点重量 当作还在乎的理由\n欺骗自己 比忘记她 容易多少\n\n[verse]\n(Chords: Cmaj7 - G/B - Am7 - Dsus4 - D)\n(Vocal-Perf: Returns to a softer dynamic, but with more weight and sorrow than the first verse.)\n(Inst: The full band continues, but the drums simplify to a basic kick-snare pattern, letting the vocal breathe.)\n(Mix: Instruments pull back slightly to refocus attention on the lyrics.)\n(Transition: Drum fill and string swell build energy directly into the next chorus.)\n朋友说 该打开门窗透透气\n我点头 却把窗帘关更紧\n她走的那天下午 阳光斜进来\n晒得我胸口 到现在还发烫\n\n[chorus]\n(Chords: G - D/F# - Em7 - Cmaj7)\n(Vocal-Perf: Most powerful and impassioned delivery; full chest voice with a noticeable emotional crack.)\n(Inst: Strings are more prominent, drums are stronger with cymbal crashes on accents. A subtle backing vocal harmony enters.)\n(Mix: The widest and fullest point of the song. Vocals are layered and sit comfortably within the lush arrangement.)\n她不需要我 她过得好不需要我好\n我全都明白 却不能替自己解释什么\n把那件毛衣叠了又叠 压在心口\n压着她给过我的 那一点点温柔\n\n[outro]\n(Chords: G - D/F# - Em7 - Cmaj7)\n(Inst: All instruments fade out except for the solo acoustic guitar, which repeats the intro motif.)\n(Vocal-Perf: A final, quiet, breathy ad-lib might be whispered over the guitar.)\n(Mix: A long reverb tail on the final guitar chord fades slowly to silence.)\n(Structure: Gradual decrescendo and instrumental fade.)",
  "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：褪色的米白与枯草黄在画面中央缓慢渗透交融，边缘沉入一层薄薄的暖灰，如同旧棉织物在光线中泛出的陈旧气息，整体像是被时间久压后留下的布料印痕，带有无声的滞重感。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。",
