  "prompt": "Genre: Pop Rap / Trap; BPM: 107; Key: G minor; Rhythm: Mid-tempo, half-time trap groove with skittering 16th-note hi-hats and a heavy, syncopated 808 bass pattern that locks into the kick on beats 1 and 3; Instruments: Sampled 2000s R&B piano (filtered, lo-fi artifacts), deep resonant 808 sub-bass, crisp Roland TR-808 hi-hats, sharp/snappy snare; Vocals: Male, smooth conversational rap flow in a mid-to-low tenor range, effortless delivery, minimal strain, supported by pitched & chopped female vocal sample hooks and crisp rhythmic ad-libs; Mood: Walking through a silent, high-end hotel lobby at 3 AM, the city lights reflecting off the polished marble floor, a sense of detached, effortless cool; Highlight: The moment the low-pass filter fully opens on the sampled piano and the iconic female vocal chops enter, establishing the entire song's luxurious hook in the first 5 seconds.",
  "title": "白手套",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Dominant filtered sub-bass, recessed mids. Stereo field is wide but centered on the sample. Vocals are treated as an instrument, panned and filtered.)\n(Inst: Filtered R&B piano, pitched female vocal chops.)\n(Sound-Design: Tape hiss, subtle vinyl crackle.)\n嗯\n\n[chorus]\n(Hook-DNA: Rhythmic spelling motif using chopped female vocals, syncopated against piano chords, repeats with slight variations, anchors on the tonic.)\n(Melody-Contour: Rapped melody is mostly monotonic with slight downward inflections at phrase ends. The sampled vocal provides the primary melodic contour, an arching phrase.)\n(Melody-Rhythm: Rapped vocals land slightly behind the beat, relaxed and conversational. Sampled vocal chops land squarely on the downbeats.)\n(Melody-Harmonic-Tension: The main rap is rhythmic and doesn't create harmonic tension; tension comes from the sustained notes of the sampled vocals against the changing piano chords, creating momentary suspensions.)\n(Mix: Low-pass filter opens completely. Full frequency spectrum. 808 sub-bass becomes the foundation. Snare is punchy and tight.)\n(Inst: Full piano sample, 808 sub-bass, trap hi-hats/snare.)\n(Vocal-Perf: Confident, laid-back flow, almost spoken. Female sample is clean and bright.)\n(Chords: Gm - Eb - Bb - F)\n白手套 送进门\n签完字 不回头\n数字后面加个零\n这才叫真的赢\n\n[verse]\n(Mix: Slightly less 808 presence than chorus, creating dynamic contrast. Vocals brought forward.)\n(Inst: Piano loop, steady 808 bass line, consistent hi-hat pattern.)\n(Vocal-Perf: More narrative and conversational. Rhythmic patterns become more complex and syncopated.)\n(Chords: Gm - Eb - Bb - F)\n二十楼落地窗看下去全是蚂蚁\n以前住地下室月租压着我喘气\n现在桌上摆的全是橡木和荔枝\n牛排几成熟 管家候着不敢提\n他们问我秘诀 我说睡得比你晚起得比你早一截\n把那些质疑的话截图存进文件夹\n每一条都变成油箱里加满的油\n路上没红灯 开到顶\n钱不只是纸 是底气\n从没人托我 白手起\n\n[chorus]\n(Mix: Energy returns to peak levels. Wider stereo on background elements.)\n(Hook-DNA: Rhythmic spelling motif using chopped female vocals, syncopated against piano chords, repeats with slight variations, anchors on the tonic.)\n(Melody-Contour: Rapped melody is mostly monotonic with slight downward inflections at phrase ends. The sampled vocal provides the primary melodic contour, an arching phrase.)\n(Melody-Rhythm: Rapped vocals land slightly behind the beat, relaxed and conversational. Sampled vocal chops land squarely on the downbeats.)\n(Melody-Harmonic-Tension: The main rap is rhythmic and doesn't create harmonic tension; tension comes from the sustained notes of the sampled vocals against the changing piano chords, creating momentary suspensions.)\n(Inst: Full piano sample, 808 sub-bass, trap hi-hats/snare.)\n(Vocal-Perf: Confident, laid-back flow, almost spoken. Female sample is clean and bright.)\n(Chords: Gm - Eb - Bb - F)\n白手套 送进门\n签完字 不回头\n数字后面加个零\n这才叫真的赢\n\n[bridge]\n(Mix: Instruments stripped back, creating space. Reverb on the spoken vocal.)\n(Inst: Filtered piano, sustained sub-bass note.)\n(Vocal-Perf: Shift to direct-address, spoken word. Intimate and dry.)\n(Melody-Harmonic-Tension: Tension created by the lack of rhythmic drive and the sustained, unresolved bass note under the spoken dialogue.)\n(Transition: Abrupt cut into the next verse.)\n你说运气\n我说复利\n\n[verse]\n(Mix: Full instrumental re-enters abruptly. Maximum energy for a verse.)\n(Inst: Full drum kit, 808, piano loop.)\n(Vocal-Perf: Flow becomes more assertive and rhythmically dense, reflecting the content.)\n(Chords: Gm - Eb - Bb - F)\n他们握手时西装袖口露出来的表\n我认得出 那块我妈攒了三年才敢摸\n现在同款压箱底都忘了在哪格\n不是炫耀 是记住那段饿着的感觉值得\n凌晨四点回复最后一封邮件落款\n天亮收到转账确认 沉默地点开看\n不发朋友圈 不需要掌声\n冰箱里备着家乡的腊肠\n那才是我真正扎根的地方\n弟弟学费今年我全包 妈别担\n账单摞起来比我当年的梦还厚\n但我都压得住\n\n[outro]\n(Mix: Elements begin to filter out. Low-pass filter slowly closes on the entire track.)\n(Inst: Piano loop, vocal chops, fading 808.)\n(Vocal-Perf: Final ad-libs with heavy delay/reverb trails.)\n(Sound-Design: Track fades out on the filtered piano loop and a final vocal chop.)\n白手套 送进门\n签完字 不回头\n数字后面加个零\n这才叫真的赢",
