    "scene_description": "黄昏最后一缕光线穿透空旷的铁轨，向看不见尽头的远方无限延伸。天空被浓稠的暮色浸染成深紫与暗橘交融的色调，铁轨两旁是枯黄的野草在微风中轻轻摇曳，整个世界仿佛正在缓慢地沉入无边的夜色之中。",
    "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：黄昏最后一缕光线穿透空旷的铁轨，向看不见尽头的远方无限延伸。天空被浓稠的暮色浸染成深紫与暗橘交融的色调，铁轨两旁是枯黄的野草在微风中轻轻摇曳，整个世界仿佛正在缓慢地沉入无边的夜色之中。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": "歌曲以BPM 66的慢速R&B承载深沉的失去与思念情绪，整体基调是回忆感与孤独感交织的内省氛围，适合用空旷风景隐喻'慢慢褪色却无法挽回'的情感内核。暮色中无尽延伸的铁轨传达出无力追赶的遗憾与渐行渐远的宿命感。"
