  "prompt": "Genre: Mandopop / Neo-Soul / Funk; BPM: 172; Key: Dm; Rhythm: Tight, syncopated funk groove with a half-time feel. 16th-note hi-hats over a laid-back kick/snare.; Instruments: Dry funk drums; clean, melodic e-bass; funky rhythm guitar (wah); smooth lead guitar fills; jazzy Rhodes chords; subtle synth pad.; Vocals: Male. Smooth, light tenor using a breathy falsetto for soaring R&B runs. Relaxed verses. Lush, layered backing harmonies.; Mood: Driving through a city late at night, streetlights on wet pavement, the comfortable loneliness of an observer.; Production: High-fidelity polish with analogue warmth. Vocals sit in a wide, detailed stereo mix with tasteful effects.; Language: Chinese; Highlight: The instant the full band enters on the first chorus, lifting the vocal from a low verse line to a sustained, high falsetto note.",

  "lyrics": "[intro]\n(Chords: Am9 - Dm9 - G13 - Cmaj9)\n(Inst: Clean funky guitar riff with wah, smooth Rhodes chords, melodic bassline, tight drums establish the groove.)\n(Mix: Wide stereo field, instruments clearly separated. Intimate and clean.)\n(Vocal-Perf: Breathy, wordless ad-libs enter, setting a cool, relaxed tone.)\n\n[verse]\n(Chords: Am9 - Dm9 - G13 - Cmaj9)\n(Inst: Arrangement thins out. Bass and drums hold the core groove, Rhodes plays sparse voicings. Guitar plays muted stabs.)\n(Vocal-Perf: Conversational, lower-register chest voice. Relaxed and rhythmic phrasing.)\n(Melody-Contour: Mostly static with small stepwise movements.)\n洗碗槽里泡着两个昨晚的杯子\n肥皂沫还没散\n我站在厨房门口没有进去\n冰箱嗡嗡转着\n把沉默变成一种白噪音\n指甲划过瓷砖缝\n留不下任何印记\n\n[pre-chorus]\n(Chords: Fmaj7 - G7 - Em7 - Am7)\n(Transition: Drums build slightly with subtle tom fills.)\n(Inst: Chord progression creates tension. Guitar becomes more sustained.)\n(Vocal-Perf: Melody ascends, increasing in intensity towards the chorus. Building dynamics.)\n翻出旧照片才发现\n你的脸已经模糊成一块光斑\n我把它放回抽屉最底层\n压在一张没寄出去的明信片下面\n连邮票都还没撕开\n\n[chorus]\n(Chords: Dm9 - G13 - Cmaj9 - Fmaj7)\n(Transition: Full band kicks in on the downbeat, dynamic lift.)\n(Inst: Lush arrangement. Layered backing vocals create a wide harmonic pad. Rhythm guitar is more active.)\n(Vocal-Perf: Jumps to a smooth, airy falsetto. More sustained notes and emotional delivery.)\n(Melody-Contour: Soaring arch shape, the peak of the song's melodic range.)\n有些东西留下来的方式\n是浮在水面上的印\n按不平\n擦不净\n你不在了以后反而更清晰\n刻进我不经意摸到的地方\n\n[verse]\n(Chords: Am9 - Dm9 - G13 - Cmaj9)\n(Inst: Energy drops back to verse 1 level, but with more intricate lead guitar fills responding to the vocal.)\n(Vocal-Perf: Returns to a controlled chest voice, maintaining the cool demeanor.)\n衬衫第三颗扣子总是松的\n你说过帮我缝\n我后来自己用胶带粘上的\n路口那家干洗店换了招牌\n新老板不认识我\n我也懒得再解释那件外套的折痕\n\n[bridge]\n(Chords: Fmaj7 - G7 - Cmaj7 - C7)\n(Transition: A clear harmonic shift signals a new section.)\n(Inst: The C7 chord adds a bluesy tension. The arrangement feels more spacious, preparing for the final chorus.)\n(Vocal-Perf: Reflective and slightly more forceful delivery, bridging the narrative gap.)\n不是舍不得\n是忘记这件事本身\n比记住更费力气\n就像把墨水滴进清水里\n想捞回来\n反而搅得哪里都是\n还不如由它去\n沉到杯底慢慢澄清\n\n[chorus]\n(Chords: Dm9 - G13 - Cmaj9 - Fmaj7)\n(Inst: Highest energy level. Drums are more powerful, cymbals more present. All instrumental layers are active.)\n(Vocal-Perf: Strongest delivery, combining falsetto with more powerful chest voice ad-libs. More complex R&B runs.)\n(Mix: Vocals are upfront and center, surrounded by the full band.)\n有些东西留下来的方式\n是浮在水面上的印\n按不平\n擦不净\n你不在了以后反而更清晰\n刻进我不经意摸到的地方\n\n[outro]\n(Chords: Dm9 - G13 - Cmaj9 - Am9 vamp)\n(Transition: Music begins a slow fade while new elements are introduced.)\n(Inst: Band vamps on the progression. Lead guitar plays melodic ad-libs.)\n(Vocal-Perf: Improvised vocal runs and the phrase \"I just got so blue\" repeated with variation. Fades out.)\n(Sound-Design: The sound of rustling paper enters and becomes the final sound as the music fades completely.)\n还留着\n还留着\n就这样留着",
