  "prompt": "Genre: Mandopop / Ballad; BPM: 140; Key: E major; Rhythm: Slow, building half-time feel with arpeggiated piano, joined by a powerful acoustic kit backbeat (kick on 1, snare on 2/4) and simple root-note bass in the chorus; Instruments: Clean grand piano (arpeggios/block chords), lush string section (pads/counter-melodies), subtle acoustic guitar (strumming), clean electric bass, powerful acoustic drum kit; Vocals: Female, clear and emotive mid-range, shifting from breathy and conversational in verses to powerful and belted in choruses, with prominent hall reverb; Mood: Sitting alone on a quiet bus at night, watching rain-streaked city lights blur past; Production: Polished studio sound with a wide stereo image, vocals are upfront, mix builds from intimate to epic with layered reverb creating emotional depth; Structure: Intro - Verse - Chorus - Verse - Chorus - Bridge - Outro; Language: Mandarin; Highlight: The soaring, nostalgic chorus melody beginning with a memorable anacrusis",
  "title": "留灯",
  "lyrics": "[intro]\n(Chords: E - B/D# - C#m - A)\n(Inst: Solo cello melody over arpeggiated grand piano. Melancholic, spacious.)\n(Mix: Narrow, intimate. Heavy reverb on cello.)\n(Sound-Design: A sense of quiet solitude is established.)\n\n[verse]\n(Chords: E - B/D# - C#m - C#m/B - A - E/G# - F#m7 - B)\n(Vocal-Perf: Soft, breathy, conversational chest voice. Mezzo-piano.)\n(Inst: Piano continues arpeggios, sparse bass notes enter.)\n(Mix: Vocal is very forward and dry, piano is wide.)\n(Melody-Contour: Mostly stepwise motion, narrative feel.)\n搬家那天下着雨\n钥匙还在门垫底下藏着\n新住户把花盆挪了位\n整条走廊的气味变了\n我站在对街看那扇窗\n灯光是完全陌生的颜色\n原来一个地址\n可以彻底变成别人的家\n\n(Transition: String swells enter, building tension.)\n[chorus]\n(Chords: A - E/G# - C#m7 - Bsus4 - B - A - E/G# - F#m7 - B)\n(Vocal-Perf: Stronger, more open chest voice. Mezzo-forte. Emotional lift.)\n(Inst: Full band enters. Acoustic drums with a simple, solid backbeat. Lush strings provide a wide pad. Bass plays root notes.)\n(Mix: Expands to full stereo width. Vocals have a longer, brighter reverb tail.)\n(Melody-Harmony: Memorable anacrusis on '那盏灯'. Soaring, diatonic melody.)\n那盏灯 还亮在旧地址\n那盏灯 照的已不是你\n那盏灯 烧穿了整个夜\n只剩我 站在灯圈外面哭\n我记得墙上那道划痕\n记得窗帘的折法\n记得每一块地板\n哪一块踩下去\n会发出声响\n灯还在\n人散了\n\n(Transition: Drums and strings drop out, piano motif leads into next verse.)\n[verse]\n(Chords: E - B/D# - C#m - C#m/B - A - E/G# - F#m7 - B)\n(Vocal-Perf: Returns to a softer, more reflective delivery, but with more weight than Verse 1.)\n(Inst: Piano and bass carry the section. Subtle acoustic guitar strumming adds texture.)\n(Mix: Narrows slightly, creating dynamic contrast with the chorus.)\n整理旧物的下午\n翻出一张没寄出的明信片\n字迹是那时候的我\n写的是准备说却没说的话\n城市把很多事压平\n让时间看起来连贯\n但那张明信片\n皱褶从来没有消失过\n有些事情折叠比失去更重\n\n(Transition: Drum fill and string crescendo lift into the second chorus.)\n[chorus]\n(Chords: A - E/G# - C#m7 - Bsus4 - B - A - E/G# - F#m7 - B)\n(Vocal-Perf: Full power, belted. Forte. Ad-libs added for emotional emphasis.)\n(Inst: Full band, more active cymbal work, strings are more prominent with counter-melodies.)\n(Mix: Widest and loudest point so far. Vocals are layered, powerful.)\n那盏灯 还亮在旧地址\n那盏灯 照的已不是你\n那盏灯 烧穿了整个夜\n只剩我 站在灯圈外面哭\n我记得墙上那道划痕\n记得窗帘的折法\n记得每一块地板\n哪一块踩下去\n会发出声响\n人散了\n\n(Transition: A sustained chord hangs, creating a pause before the bridge.)\n[bridge]\n(Chords: A - B - G#m7 - C#m7 - F#m7 - B - E)\n(Vocal-Perf: Starts intimately, then builds to a powerful climax. A mix of desperation and nostalgia.)\n(Inst: Drums become more powerful with tom fills. Piano plays strong block chords. Strings soar.)\n(Mix: The emotional peak. All elements at maximum intensity.)\n那盏灯 是我替你留的\n那盏灯 烧掉了我的手\n那盏灯 变成疤以后\n才明白 有些等待是囚\n我抱着那盏灯的灰\n把自己也一起点燃\n直到连疼痛都蒸发\n最烫的从前\n最冷的现在\n\n(Transition: Music suddenly becomes sparse, leaving piano and a single cello line.)\n[outro]\n(Chords: A - B - E - C#m - F#m - B - E)\n(Vocal-Perf: Resigned, soft, almost a whisper at the end. Decrescendo.)\n(Inst: Piano plays simple, final chords. Solo cello line echoes the intro.)\n(Mix: Rapidly narrows. Reverb becomes very long as elements fade out.)\n那盏灯\n我关掉\n摸黑坐\n不开灯\n黑暗比照亮更诚实\n太亮了\n才看见\n我一直\n一个人",
  "cover_prompt": "A single amber streetlamp casting a perfect circle of warm light on rain-wet dark asphalt, viewed from directly above as a bird's-eye perspective. The lamp itself is invisible — only its light pool exists, a glowing oval surrounded by absolute darkness. Tiny reflected ripples in the puddles break the light into scattered gold fragments. High contrast, cinematic, melancholic. Deep black background, warm gold light pool, no people, no text, no faces, square format.",

    "scene_description": "俯视视角正对雨后柏油路面，路灯本体不可见，只有一圈完整的琥珀色灯晕投射在湿黑地面上，水洼将光芒碎裂成细碎金片散落四周。灯圈之外是绝对的黑暗，以「光的形状」代替「灯的实体」，视觉上呼应骨架词「灯」从存在到消散的全程。",

    "selection_reason": "骨架词「灯」在全曲含义递进：等待之灯→失去之灯→燃烧之灯→熄灭之灯。俯视灯晕构图让「灯」以光的投影而非实体出现，暗合歌词末句「关掉那盏灯」后只剩黑暗的意境，封面与叙事终点形成视觉呼应。"
