  "prompt": "Genre: Mandopop / R&B / Classical Crossover; BPM: 87; Key: F minor; Rhythm: Slow, heavy hip-hop groove with a steady kick/snare backbeat and running 16th-note hi-hats. Syncopated and atmospheric; Instruments: Dark, resonant Acoustic Piano playing Chopin-esque arpeggios, clean Nylon String Guitar for fills, lo-fi Hip-Hop drum machine, lush cinematic string pads; Vocals: Male tenor with a smooth, slightly nasal timbre. Verses are a half-spoken, half-rapped rhythmic delivery, choruses are melodic and breathy. Processed with prominent hall reverb and delay; Mood: Standing alone in a fog-shrouded gothic cemetery at twilight, the air cold and heavy with the smell of damp earth and wilting flowers after a funeral; Highlight: The high, sustained vocal note on the final word of the hook ('愛情'), held over the descending classical piano arpeggios, creating a moment of soaring, romantic tragedy.",
  "title": "潮汐线",
  "lyrics": "[intro]\n(Chords: Fm - C7/E - Fm/Eb - Bbm/Db)\n(Inst: Solo grand piano playing a descending, arpeggiated figure. Dark, resonant tone with heavy sustain. Establishes the classical nocturne theme.)\n(Mix: Centered piano, wide stereo reverb.)\n\n[verse]\n(Chords: Fm - C7 - Fm - Bbm - Fm - C7 - Fm)\n(Inst: Lo-fi hip-hop drum beat enters with a solid backbeat and 16th-note hi-hats. Piano continues arpeggios. A clean nylon string guitar plays subtle counter-melodies.)\n(Vocal-Perf: Rhythmic, half-spoken, half-rapped delivery. Precise diction, low dynamic range, conversational tone.)\n冰箱贴还在 但磁力已经散了\n那张合照压在键盘下面 我假装没看见\n你走的那天 窗帘还是你选的那款\n阳光透进来 照的全是你不在的地方\n我学会了把两人份煮成一人份\n计时器响了 没有人替我关掉它\n\n[chorus]\n(Chords: Dbmaj7 - Abmaj7 - Eb - Fm)\n(Inst: Texture thickens. Lush, cinematic string pads enter, providing a sorrowful harmonic bed. Piano plays fuller chords mixed with arpeggios. Sub-bass grounds the progression.)\n(Vocal-Perf: Shifts to a fully melodic, sung performance. Breathy, emotional tone, rising in pitch and intensity. Subtle backing vocals for harmony.)\n我把你的名字存成了陌生人\n只为了骗自己已经忘记\n潮汐线压在礁石最低处的印\n涨潮前最清晰\n那些说好一起去的地方\n我一个人去了 又一个人离开\n带回来的只有耳鸣\n\n[verse]\n(Chords: Fm - C7 - Fm - Bbm - Fm - C7 - Fm)\n(Inst: Texture returns to the sparser feel of the first verse. Strings recede, focusing on the piano, drums, and nylon guitar.)\n(Vocal-Perf: Returns to the rhythmic, narrative style. A sense of quiet desperation in the delivery.)\n啊 体检报告上填紧急联系人\n我停顿了三秒 然后填了我妈的号码\n朋友说你好像过得不错\n我点了点头 续了杯水 换了个话题\n那种卡在喉咙里的问句\n问出来没意义 咽下去又不甘心\n啊 深夜里打开备忘录\n啊 写了一半又全删掉\n留下空白页\n\n[bridge]\n(Chords: Bbm - Fm/Ab - Gm7b5 - C7sus4 - C7 - Fm)\n(Inst: Chord progression becomes more tense and dramatic, creating a sense of unease. Strings swell slightly to underscore the emotional shift.)\n(Vocal-Perf: Delivery becomes more impassioned and slightly louder, straddling the line between singing and emotive speech.)\n有人说时间会把一切填平\n我掐着日历数了整整四百天\n该结痂的地方还是怕碰\n只是学会了不在人前提起\n我不是没想过就此翻篇\n只是翻到那一页的时候\n总有一个细节没防备\n比如你惯用的那支笔\n还搁在我书桌右边第三格\n\n[chorus]\n(Chords: Dbmaj7 - Abmaj7 - Eb - Fm)\n(Inst: The fullest arrangement. Strings are prominent, piano is powerful. The beat drives forward with weight.)\n(Vocal-Perf: Peak emotional delivery. Lead vocal is clear and soaring, especially on the high notes. Layered harmonies are more audible.)\n我把你的名字存成了陌生人\n只为了骗自己已经忘记\n潮汐线压在礁石最低处的印\n涨潮前最清晰\n那支笔还有墨 那个格子还空着\n我绕过去 假装那里什么都没发生\n原来放不下的从来不是你\n是那些你留下来的细节\n\n[interlude]\n(Chords: Fm - C7 - Fm - Bbm - Fm - C7 - Fm)\n(Inst: Vocals drop out. The nylon string guitar takes the lead, playing a melancholic, slightly virtuosic melody over the core piano and drum groove. Strings hold long, soft pads in the background.)\n(Mix: Guitar is brought forward in the mix with a touch of extra reverb.)\n\n[outro]\n(Chords: Fm - C7 - Fm - Bbm)\n(Inst: The drum beat and bass fade out, leaving only sparse piano arpeggios. Music gradually decelerates.)\n(Vocal-Perf: A near-whisper, reprising the opening lines with a feeling of finality and exhaustion. Heavy reverb tails.)\n(Sound-Design: A subtle sound of wind fades in as the music fades out, ending on a single, unresolved piano note.)\n冰箱贴还在 但磁力已经散了\n那张合照压在键盘下面 我假装没看见",
  "cover_prompt": "生成一张极简主义的抽象环境光晕（Ambient Aura）图片作为无字音乐专辑封面。画面的核心色彩组合与情绪倾向是：深沉的铁灰蓝与褪色的潮湿砂岩色之间极其平滑的渐变，仿佛大潮退去后礁石上残留的水痕，在极度柔焦中漫溢出一种无声的、绵延不绝的疲惫感。画面完全由纯粹的色彩构成，采用极度的柔焦（Soft focus）和重度模糊效果（Blurred effect），使得不同颜色之间产生极其平滑、如丝绸般的无缝过渡。整体质感极致平滑细腻（Smooth texture），没有任何杂质。强烈要求：这是一张彻底抽象的现代色彩场（Color Field）作品，绝对不要出现任何具体的物体、几何图案或锐利的边缘！不需要任何胶片颗粒感！画面必须是无字封面，绝对不要生成任何文字、拼音或英文字母，不要生成人物轮廓！传达出一种极其平静、舒缓、现代且充满呼吸感的氛围。",
