  "lyrics": "[intro]\n(Chords: Gm - Bb - Eb - F)\n(Inst: Solo upright piano playing a simple, memorable melody. Faint vinyl crackle bed.)\n(Sound-Design: Vintage warmth, slight room reverb, establishing a nostalgic atmosphere.)\n(Vocal-Perf: Gentle, slightly breathy, clear storytelling tone.)\nThe city lights went dark before I turned eighteen\nI watched the last bus leave without me on that street\nThe city lights went dark\n\n[verse]\n(Chords: ↑ same)\n(Inst: Piano settles into block chords, minimalist hip-hop kick-snare beat enters, subtle sub-bass provides foundation.)\n(Melody-Rhythm: Conversational and syncopated phrasing, sitting tightly in the pocket of the beat.)\n(Vocal-Perf: Intimate close-mic delivery, confessional, building slightly in dynamic intensity.)\nI used to draw the maps of roads I'd never traveled\nFold them into planes and watch my blueprints unravel\nThe factory floor was cold but kept my hunger level\nI swallowed every doubt and picked apart each pebble\n\n[pre-chorus]\n(Chords: ↑ same)\n(Inst: Lush cinematic strings enter with long, sustained pads, adding a layer of anticipation.)\n(Melody-Contour: Ascending melodic line, creating tension that leads into the chorus.)\n(Vocal-Perf: Increased projection and clarity, a hint of the power to come.)\n(Transition: String section swells →)\nThe warehouse walls were high the winter cut like needles\nI wrote my name in dust and prayed the cold would ease though\nThe warehouse walls were high\n\n[chorus]\n(Chords: ↑ same)\n(Hook-DNA: Repetitive, simple age-based lyrical hook; Memorable stepwise melody that starts high and resolves downwards.)\n(Melody-Contour: Anthemic, sing-along arc that creates an emotional peak.)\n(Inst: Full arrangement; driving piano, punchier drums, wide cinematic strings, lush background vocal stacks enter on key phrases.)\n(Mix: Expands to full stereo width, vocals have more reverb, creating a larger-than-life space.)\n(Vocal-Perf: Powerful chest belting, raw and emotional delivery, full voice with a touch of grit.)\nNow I'm twenty-five and the road keeps pulling forward\nI left behind the harbor for the open water\nNow I'm twenty-five years old\n\n[verse]\n(Chords: ↑ same)\n(Inst: Arrangement pulls back to piano, bass, and drums. Strings are absent, creating dynamic contrast.)\n(Melody-Rhythm: More dense and reflective phrasing, fitting more syllables per bar.)\n(Vocal-Perf: Returns to an intimate, thoughtful tone, with a more mature and world-weary quality than verse 1.)\nI found a room above a shop that smelled of motor oil\nMy neighbor left at dawn and came back burnt and loyal\nWe shared a meal on Fridays traded laughs for toil\nIn strangers I discovered what the years had foiled\n\n[bridge]\n(Chords: Eb - F - Gm - Bb)\n(Inst: Piano and strings dominate, drums are sparse. Focus on harmonic movement and space.)\n(Melody-Harmonic-Tension: Vocal melody floats over the chord changes, creating a hopeful, forward-looking feeling.)\n(Vocal-Perf: Softer, more tender delivery, using a lighter mix and head voice for emotional vulnerability.)\n(Transition: Drum fill and string swell build back into the chorus →)\nSomewhere past thirty the bridges start to matter\nYou count the ones still standing after all the scatter\nSomewhere past thirty we do\n\n[chorus]\n(Chords: Gm - Bb - Eb - F)\n(Hook-DNA: Repetitive, simple age-based lyrical hook; Memorable stepwise melody that starts high and resolves downwards.)\n(Melody-Contour: Anthemic, sing-along arc that creates an emotional peak.)\n(Inst: The biggest arrangement; piano, drums, strings, and now a full gospel-style choir for maximum emotional impact.)\n(Mix: Widest and most epic point of the song, vocals are powerful and sit within the grand arrangement.)\n(Vocal-Perf: Peak emotional delivery, full-throated powerful chest belting, with ad-libs weaving around the main vocal.)\nNow I'm twenty-five and the ghosts have mostly thinned out\nI built the walls I swore I'd never let them pin down\nNow I'm twenty-five years old\n\n[outro]\n(Chords: ↑ same)\n(Inst: Arrangement thins out dramatically, leaving solo piano, soft sustained strings, and the final vocal line. Ends on a single piano chord with a long, resonant decay.)\n(Sound-Design: Vinyl crackle becomes more prominent as instruments fade out.)\n(Vocal-Perf: Decrescendos to a gentle, reflective tone, bookending the song with the same intimacy as the intro.)\nThe city lights come on again I almost recognize them\nI trace the skyline back to where I first defied them\nThe city lights come on",

    "scene_description": "深夜的工业城市边缘，一个年轻男性背影站在高架桥上俯瞰远处霓虹灯光，脚下是锈迹斑斑的钢铁栏杆，远处工厂烟囱冒出白雾与橙色路灯交织，画面有胶片颗粒质感，色调以冷蓝与琥珀暖橙对比，暗示青春与前路的张力",
    "cover_prompt": "Cinematic album cover, a solitary young man's silhouette seen from behind standing on an industrial overpass at night, gazing at a distant cityscape glowing with amber streetlights and cool blue factory smoke, rusty iron railings in foreground with peeling paint, warm orange and cold steel-blue color contrast, heavy film grain texture, shallow depth of field, moody and introspective atmosphere, no text, no faces, no watermark, photorealistic with painterly color grading, 2048x2048 square format",
    "selection_reason": "歌词核心意象是城市灯光熄灭与重燃、独自离港的旅程感；工业高架桥视角既呼应工厂/仓库的成长叙事，背影构图又保留情绪的内敛与前瞻，胶片颗粒与复古色调匹配原曲的vinyl crackle老式灵魂质感"
