  "title": "落潮",
  "lyrics": "[intro]\n(Chords: Cm7 - Gm7 - Fm7 - G7)\n(Inst: Clean electric guitar plays a melancholic, blues-inflected motif. Breathy male vocal hums enter. Muted trumpet echoes guitar line.)\n(Mix: Intimate, narrow stereo field. Guitar slightly panned right.)\n(Vocal-Perf: Soft, airy hums. Setting a contemplative tone.)\n\n[verse]\n(Chords: Cm7 - Cm7 - Fm7 - G7sus4 - G7)\n(Inst: Bass and a simple half-time drum groove enter. Kick on 1, layered snare on 3. Guitar continues with sparse arpeggios.)\n(Vocal-Perf: Conversational, mellow chest voice. Mezzo-piano dynamics. Clear enunciation.)\n(Melody-Contour: Mostly stepwise motion, relaxed phrasing.)\n(Transition: Subtle hi-hat fill leads into pre-chorus.)\n潮水退去\n沙滩上只剩贝壳和倦意\n脚印深一些\n走到哪又去哪\n风吹来 带走沙粒 也带走话\n\n[pre-chorus]\n(Chords: Abmaj7 - Bb7 - Ebmaj7 - Gm7)\n(Inst: Rhodes piano chords and string pads swell in, adding warmth and building tension. Bass becomes more melodic.)\n(Mix: Stereo width increases slightly. Strings add depth.)\n(Vocal-Perf: Rises in pitch and intensity. A touch more emotional weight.)\n(Melody-Dev: Ascending line creates anticipation for the chorus.)\n说过的诺言\n淡成海平线\n不是不记得\n只是海浪拍打了太多遍\n\n[chorus]\n(Chords: Cm7 - Fm7 - Abmaj7 - G7sus4 - G7)\n(Inst: Full band texture. Lush string section soars. Guitar plays chordal stabs and fills. Muted trumpet adds soulful counter-melodies.)\n(Vocal-Perf: Mezzo-forte, more sustained notes. Tasteful R&B runs on phrase ends. Layered background vocals for harmony.)\n(Mix: Wide, cinematic soundscape. Vocals sit powerfully in the center.)\n(Sound-Design: Plate reverb on vocals is more prominent.)\n灯塔亮着\n船已靠岸\n可等的人不在甲板\n雾散了\n才看清来时的路\n原来弯了这么多弯\n哦\n放不下 拦不住 又何苦\n潮起落 人来去 皆是渡\n\n[verse 2]\n(Chords: Cm7 - Cm7 - Fm7 - G7sus4 - G7)\n(Inst: Arrangement pulls back slightly, but drums and bass remain, maintaining momentum. Rhodes is more present than in verse 1.)\n(Vocal-Perf: Returns to a more intimate delivery, but with lingering intensity from the chorus.)\n(Melody-Rhythm: More syncopated and rhythmically playful than the first verse.)\n(Transition: Strings fade back in at the end of the section.)\n码头安静\n鸥鸟停在锈迹斑斑的栏杆上\n夕阳压得低\n把影子拉得很长 很长\n渔网晾干 旧事风干\n\n[bridge]\n(Chords: Abmaj7 - Bb/Ab - Gm7 - Cm7 - Fm7 - G7sus4 - G7)\n(Inst: Dynamic build. Drums become busier with more cymbal work. Strings play a more dramatic, ascending figure.)\n(Vocal-Perf: Pushes into a stronger, more desperate tone. The highest point of vocal intensity before the final chorus.)\n(Mix: All elements push forward, creating a dense, emotional peak.)\n涨潮时以为能触碰远方\n退潮后才懂礁石有多硬\n还是回头走\n\n[chorus]\n(Chords: Cm7 - Fm7 - Abmaj7 - G7sus4 - G7)\n(Inst: Climax of the song. All instruments play at full intensity. Trumpet and guitar play more impassioned ad-libs.)\n(Vocal-Perf: Full power. More prominent falsetto ad-libs and runs weave around the main vocal. Background vocals are thick and supportive.)\n(Mix: Maximum width and depth. Everything feels large and resonant.)\n灯塔亮着\n船已靠岸\n可等的人不在甲板\n雾散了\n才看清来时的路\n原来弯了这么多弯\n哦\n放不下 拦不住 又何苦\n潮起落 人来去 皆是渡\n\n[outro]\n(Chords: Cm7 - Gm7 - Abmaj7 - G7)\n(Inst: Instruments begin to fade out, leaving guitar, muted trumpet, and soft Rhodes. Beat plays a few more bars then stops.)\n(Vocal-Perf: Final phrase delivered in a soft, resigned falsetto. Breathy ad-libs.)\n(Mix: Gradual fade out. Reverb tails linger.)\n(Sound-Design: A final, distant trumpet lick closes the track.)\n哦\n海还在",

    "scene_description": "黄昏时分的废旧码头，锈蚀的铁栏杆上停着一只海鸥，远处灯塔微光亮起，退潮后的沙滩留下弯曲的脚印延伸至画面边缘，整体笼罩在橙紫色暮光之中，氛围静谧而惆怅",
    "cover_prompt": "A weathered harbor dock at dusk, a single seagull perched on a rust-stained iron railing, a distant lighthouse glowing faintly through hazy violet-orange twilight, wet sand exposed by low tide stretching into the foreground with faint curved footprints, moody cinematic color grading with deep teal shadows and warm amber highlights, no people, no text, no watermark, photorealistic atmospheric landscape, wide aspect ratio cropped to square",
    "selection_reason": "歌词以退潮、码头、灯塔为核心意象，情绪内敛而深沉，风景类封面能直观呈现这种孤寂与释然并存的气质，橙紫暮光与R&B/Soul曲风的慵懒感高度契合"
