  "lyrics": "[intro]\n(Chords: A - D - A - E | A - D - A - E - A)\n(Inst: Signature melodic electric guitar riff, slightly overdriven tone. Full band enters with punchy drums, solid bass, and clean rhythm guitar.)\n(Mix: Guitar centered, then opens to full stereo width when band enters.)\n\n[verse]\n(Chords: A - Bm7 - E - A | D - E - C#m - F#m | Bm7 - E - A)\n(Vocal-Perf: Relaxed, breathy, conversational tone, lower range.)\n(Inst: Dynamics drop. Bass and drums hold a simple groove. Clean electric guitar plays arpeggios. Sparse, bluesy lead guitar fills answer vocal lines.)\n(Mix: Vocals prominent and centered. Spacious feel.)\n(Transition: Drum fill and cymbal swell building energy.)\n路灯把影子拉得好长\n风掀动衣角像海浪的形状\n反复滑过你那条朋友圈的日常\n却从不敢留下痕迹 只默默收藏\n咖啡凉透了第三杯还在逞强\n指尖贴上屏幕又缩回掌\n\n[chorus]\n(Chords: A - E/G# - F#m - E | D - C#m - Bm7 - E)\n(Vocal-Perf: Stronger, more open-throated, higher range, more melodic.)\n(Melody-Contour: Ascending phrase, catchy and memorable.)\n(Inst: Full band energy. Driving rhythm section. Strummed acoustic guitar adds texture. Subtle organ pads add warmth.)\n(Mix: Wide, full, layered sound.)\n你是四月转角猝不及防的丁香\n是暴雨前闷热空气里裹着的滚烫\n是写满了又整页撕掉的草稿箱\n是凌晨手机亮起又灭下去的光\n我想大步走向你 脚却灌了铅一样\n揣着满兜的话 一句都说不响\n\n[interlude]\n(Chords: A - D - A - E | A - D - A - E - A)\n(Inst: Main electric guitar riff returns, serving as a melodic hook. Band maintains a solid groove.)\n(Transition: Clean dynamic drop back to verse feel.)\n\n[verse]\n(Chords: A - Bm7 - E - A | D - E - C#m - F#m | Bm7 - E - A)\n(Vocal-Perf: Similar to first verse, slightly more confident and embellished delivery.)\n(Inst: More active and intricate lead guitar fills. Organ is slightly more audible.)\n(Mix: Consistent with first verse, maintaining space for vocals.)\n(Transition: Stronger drum fill builds anticipation for the chorus.)\n你笑的时候空气变成蜜糖\n我站在你三步开外的地方\n排练千遍的开场白全散了场\n只剩心跳乱得砰砰作响\n转身假装赶路的模样\n\n[chorus]\n(Chords: A - E/G# - F#m - E | D - C#m - Bm7 - E)\n(Vocal-Perf: Full power, emotional and invested.)\n(Inst: All layers present, driving energy. Crash cymbals on beat 1.)\n(Mix: The densest mix so far, powerful and engaging.)\n你是四月转角猝不及防的丁香\n是暴雨前闷热空气里裹着的滚烫\n是写满了又整页撕掉的草稿箱\n是凌晨手机亮起又灭下去的光\n我想大步走向你 脚却灌了铅一样\n揣着满兜的话 一句都说不响\n\n[interlude]\n(Chords: A - E/G# - F#m - E | D - C#m - Bm7 - E)\n(Inst: Expressive electric guitar solo. Melodic, blues-influenced phrasing with tasteful bends and vibrato. Rhythm section provides tight support.)\n(Vocal-Perf: Ad-lib vocalizations underneath the solo.)\n(Mix: Solo is front and center, with a touch of delay and reverb.)\n(Transition: Solo builds to a melodic peak before a smooth handoff to the final chorus.)\n\n[chorus]\n(Chords: A - E/G# - F#m - E | D - C#m - Bm7 - E)\n(Vocal-Perf: Peak energy, powerful ad-libs over the main melody.)\n(Inst: Maximum intensity from the full band.)\n(Mix: Loudest, widest point of the song.)\n你是四月转角猝不及防的丁香\n是暴雨前闷热空气里裹着的滚烫\n是写满了又整页撕掉的草稿箱\n是凌晨手机亮起又灭下去的光\n我拼命想抓住你 掌心全是汗在淌\n这场暗恋快要涨破了胸膛\n\n[bridge]\n(Chords: F#m - C#m - D - A | F#m - C#m - D - E)\n(Vocal-Perf: Dynamic drops suddenly. Intimate, almost spoken, vulnerable.)\n(Inst: Sparse arrangement. Clean, arpeggiated electric guitar. Bass holds root notes. Drums become very light, possibly using hot rods or brushes.)\n(Mix: Intimate, dry, vocal-focused. Creates tension and release.)\n这份心事像凝住不动的光 越透明越滚烫\n如果沉默本身也是一种珍藏\n那就让它替我守着这场独角戏散场\n\n[outro]\n(Chords: Amaj7)\n(Vocal-Perf: Final line delivered with a breathy, definitive sigh.)\n(Inst: Band hits final chord and fades. A final, lingering electric guitar lick echoes the main riff.)\n(Mix: Slow fade to complete silence.)\n都封进时光里吧\n",

    "scene_description": "一条雨后被暖黄路灯染透的空巷，湿漉漉的石板路面映着朦胧的光圈，远处城市的轮廓在薄雾中若隐若现，天空是深紫与暗橘色交叠的暮色，空气仿佛凝固了某种说不出口的温度",
    "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：一条雨后被暖黄路灯染透的空巷，湿漉漉的石板路面映着朦胧的光圈，远处城市的轮廓在薄雾中若隐若现，天空是深紫与暗橘色交叠的暮色，空气仿佛凝固了某种说不出口的温度。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": "新歌词围绕暗恋的沉默与暗涌展开，整体情绪是克制的渴望与城市感的孤独，复古空旷风景流的暖黄暮色空巷恰好承载这种'欲言又止'的氛围，与原曲sophisticated urban的气质高度吻合。"
