  "lyrics": "[intro]\n(Inst: Solo grand piano, melancholic arpeggios, spacious reverb.) (Mix: Piano front and center, wide stereo image.) (Chords: C#m - A - E - B) (Mood: Introspective, gentle sadness.)\n\n[verse]\n(Vocal-Perf: Breathy, close-mic'd, vulnerable, low-to-mid range.) (Melody-Contour: Mostly conjunct, gentle arc.) (Inst: Piano continues sparse arpeggios.) (Mix: Intimate, dry vocal with a long reverb tail.) (Chords: C#m - A - E - B)\n走了太久 连方向都模糊成一声长长的叹息\n行李箱碾过的每条街都像逃离 你在电话那头笑得那么轻 声音温柔得不像在生气\n背景里传来锅铲翻炒的声响 我才听懂 你一直没挂 只想安静听我呼吸\n\n[chorus]\n(Energy: Builds significantly.) (Vocal-Perf: Stronger, clearer tone, rising to upper register, emotive.) (Melody-Contour: Wider leaps, sustained high notes.) (Inst: Full lush string section enters, subtle bass, simple drum backbeat with soft hits.) (Mix: Wide, cinematic, vocals soar over the mix.) (Chords: A - E - B - C#m)\n我从没说过想你 怕声音泄了秘密\n眼眶装满了雨季 总在深夜三点决堤\n那些咽下去的关心 全都压进箱底\n我走得越远越清醒\n你老得越来越小心翼翼\n\n[interlude]\n(Inst: Piano melody with string pads, cello counter-melody.) (Structure: Instrumental break, releases tension from chorus.) (Chords: C#m - A - E - B)\n\n[verse]\n(Vocal-Perf: Returns to breathy, narrative tone, slight increase in emotional weight.) (Inst: Piano accompaniment with slightly more rhythmic chordal playing. Bass enters, simple root notes on the beat.) (Mix: Still intimate but with more foundation from the bass.) (Chords: C#m - A - E - B)\n后来我练就了一身在人潮中央假装完好无损的姿态\n你寄来的旧围巾我攥了一整个冬天 指尖的温度把线头都磨得快要散开\n生日那晚你只发了四个字注意身体 我反复读着 一直读到窗外天色泛白\n\n[chorus]\n(Energy: Peak emotional intensity.) (Vocal-Perf: Full power, belting notes, subtle vocal harmonies on key phrases.) (Melody-Dev: Melodic variations and ad-libs in the second half.) (Inst: Drums more prominent, cymbal crashes, strings are soaring and complex.) (Mix: Dense, powerful, epic scope.) (Chords: A - E - B - C#m)\n你知道\n我不敢说想你 怕一开口就哭到窒息\n每句还好都是演技 笑容是缝补过的外衣\n那些欠你的归期 被我藏在日记最深的褶皱里\n我越走越远才终于看清\n你连白发都不舍得让我看见一丝痕迹\n\n[bridge]\n(Energy: Drops suddenly, very exposed.) (Vocal-Perf: Almost spoken, weary, full of resignation.) (Inst: Sparse, high-register piano chords. A lone violin plays a mournful counter-melody.) (Mix: Extremely spacious, vocal feels isolated.) (Chords: F#m - C#m - A - B)\n我知道\n你把所有想念都藏进了那句早点休息\n而我连说一声谢谢 都觉得太过刻意\n我欠你一个归期 大概这辈子都还不起\n\n[outro]\n(Inst: Solo piano playing a fragmented, slowing version of the intro melody, final chord resolves on E major with lush strings.) (Sound-Design: The sound of the piano pedal releasing at the very end.) (Mix: Fades to silence.)\n大概这辈子都还不起",

    "scene_description": "黄昏将尽的时刻，一条笔直的碎石小路延伸向远方，尽头完全消融在浓稠的暮色与雾气之中，看不见终点。小路两侧是大片枯黄的芒草在风中缓慢摇曳。天空是一层层褪色的橘粉、灰紫和铅蓝交叠的渐变色，低沉的云层几乎压到地面。光线昏暗而柔软，整个画面弥漫着一种永远走不到尽头也回不了头的温柔疲惫感。",
    "cover_prompt": "生成一张拍立得（Polaroid）风格的无字版音乐专辑封面。画面描绘的是：黄昏将尽的时刻，一条笔直的碎石小路延伸向远方，尽头完全消融在浓稠的暮色与雾气之中，看不见终点。小路两侧是大片枯黄的芒草在风中缓慢摇曳。天空是一层层褪色的橘粉、灰紫和铅蓝交叠的渐变色，低沉的云层几乎压到地面。光线昏暗而柔软，整个画面弥漫着一种永远走不到尽头也回不了头的温柔疲惫感。整体画面必须呈现真实拍立得相片的质感：略微过曝的柔和光线、轻微偏色的复古色调、自然的暗角和柔焦边缘、细腻的胶片颗粒感。色彩是褪色、怀旧的暖色调，仿佛一张被遗忘在抽屉里多年的即时成像照片。强烈要求：画面必须是纯粹的风景，绝对不要出现任何人物、人影、手或脸！绝对不要生成任何文字、字母、歌名或水印！保持空灵、孤独和冥想的氛围。",
    "selection_reason": "歌曲是69BPM的慢速电影感叙事民谣，核心情绪是漂泊者对归途的无望追忆与深沉孤独感，与模板一'孤独感、回忆感、宏大悲伤的流行/民谣'高度吻合。消失在暮色中的小路隐喻了永远走不到尽头的归期。"
