  "lyrics": "[intro]\n(Chords: Am - Em/G - F - C)\n(Inst: Clean electric guitar arpeggios with light delay and reverb. Atmospheric organ pads. Layered male vocal harmonies singing 'oohs'.)\n(Mix: Wide stereo field, guitar panned, vocals centered. Dreamy and spacious.)\n(Melody-Contour: Descending vocalise.)\n\n[verse]\n(Chords: Am - G - C - F)\n(Inst: Gentle acoustic strumming enters. Bass plays simple root notes. Drums enter with a sparse, slow beat - kick on 1, snare on 3 with heavy reverb. Electric guitar continues arpeggiating.)\n(Vocal-Perf: Soft, narrative, conversational tone. Low dynamic range.)\n(Mix: Vocals sit comfortably on top of the instrumental bed.)\n铁皮车厢摇过半个省的雨季\n车窗起雾 我画了栋房子又擦去\n口袋揣着零钱 够买一盒你最烦的烟\n站台的钟停在九点零七\n广播含混得像另一种语气\n我杵在原地 忘了该去哪里\n\n[pre-chorus]\n(Chords: F - G - C - Am)\n(Inst: Drums add a light ride cymbal. Organ swells slightly in volume. Bass becomes slightly more melodic.)\n(Vocal-Perf: Intensity builds, moving into a slightly higher register. More sustained notes.)\n(Melody-Contour: Ascending, creates tension leading to the next section.)\n桂花的甜腻忽然穿过铁皮车厢 是八月的故乡千里迢迢追来的光\n我把脸埋进掌心不敢张望 怕一抬头这气味就散成了雾茫茫\n\n[verse]\n(Chords: Am - G - C - F)\n(Inst: Dynamics return to verse level. Instrumentation remains consistent.)\n(Vocal-Perf: Returns to a storytelling, lower-intensity delivery.)\n你背过我翻了三里碎石的山\n鞋底磨穿你笑着说 正好透风当凉鞋穿\n柿子树被暴雨连根拔起的那个秋天\n你蹲下用草绳一圈圈绕 绑好裂口像缝伤疤一般\n后来我坐上去远方的车\n你追到巷尾 喊的话全被风扯散\n我背对你装作没听见 泪落了半条公路才擦干\n\n[chorus]\n(Chords: C - G - Am - F)\n(Inst: Full band feel. Electric guitar plays a simple melodic counterpoint. Drums are more present but still laid-back. Organ pad is sustained and full.)\n(Vocal-Perf: More emotional and open-throated. Higher dynamics. Layered with backing harmonies.)\n(Mix: Wider and fuller sound.)\n隔了一千公里假装日子平淡\n电话拨了三遍又塞回裤兜里面\n你发来语音 就两个字 天冷\n我在深夜反复听了几十遍\n听到尾巴那声叹\n\n[interlude]\n(Chords: Am - G - C - F - Am - G - F - E7)\n(Inst: Electric guitar solo. Melodic, lyrical, with slight overdrive and long reverb tails. Drums and bass provide a simple foundation. Wordless 'ooh' vocals in the background.)\n(Mix: Guitar solo is the focus, but sits within the mix rather than on top.)\n\n[bridge]\n(Chords: Dm - Am - G - C)\n(Inst: Piano chords enter, taking a more central harmonic role. Drums are sparser, perhaps just cymbal swells and kick.)\n(Vocal-Perf: More introspective and slightly quieter, almost a whisper.)\n(Structure: Dynamic drop before the final emotional peak.)\n梦里老屋灶台蒙了一层灰\n你坐门槛缝那双裂了口的布鞋\n猫瘦成一把骨头趴在你膝盖\n你摸着它说走远的总会回来\n我想喊你却张不开嘴 喉咙像灌满了水\n惊醒时枕头湿透 窗玻璃上凝着白霜一片片往下坠\n\n[chorus]\n(Chords: C - G - Am - F)\n(Inst: Full band re-enters with energy. Layered vocals create a choral effect.)\n(Vocal-Perf: Peak emotional delivery. Ad-libs and expressive.)\n(Mix: The biggest and widest point of the song.)\n别等了 别再一个人热剩饭\n我在买最近一班回去的票\n月台风大灌满袖口的冰寒\n广播终于念了句我听得懂的站\n站名是你守着的那座山\n我拖着箱子跑 轮子轧过水泥裂缝\n这次不走了 我要站在你面前\n\n[outro]\n(Chords: Am - G - C - F, repeating and fading)\n(Inst: Harmonica enters, playing a mournful, improvisational melody. Drums, bass, and guitars slowly fade out, leaving the harmonica, lingering organ chords, and reverb tails.)\n(Vocal-Perf: Faint, distant 'oohs'.)\n(Mix: Long, slow fade to silence.)",

    "scene_description": "一条被晨雾笼罩的碎石小路蜿蜒消失在灰蓝色的远山之间，路旁是枯黄的野草和一棵被常年季风吹得倾斜的老树，天空是破晓前将亮未亮的冷靛蓝色，地面覆盖着一层薄薄的白霜正在融化，远处山脊线上隐约透出一丝暖橘色的微光",
    "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：一条被晨雾笼罩的碎石小路蜿蜒消失在灰蓝色的远山之间，路旁是枯黄的野草和一棵被常年季风吹得倾斜的老树，天空是破晓前将亮未亮的冷靛蓝色，地面覆盖着一层薄薄的白霜正在融化，远处山脊线上隐约透出一丝暖橘色的微光。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62BPM的民谣摇滚为底色，讲述离乡与归途的愧疚思念，情绪基调是怀旧、孤独、苦涩中带暖意。复古空旷风景模板的拍立得质感与褪色暖调最能承载这种'被时间搁置的牵挂'，晨雾中的碎石路隐喻漫长的归途，融化的霜与远山微光暗示终将回归的希望。"
