  "prompt": "Genre: Indie Pop / Lo-fi Singer-Songwriter; BPM: 112; Key: A minor; Rhythm: Gentle, syncopated ukulele strumming carrying a loose, behind-the-beat 4/4 groove; vocals float rhythmically free over the chords; Instruments: Close-mic'd ukulele (finger noise, wood resonance), hazy low-passed synth pad, distant sparse electric piano, found sounds (footsteps); Vocals: Female, intimate close-mic, breathy timbre with gentle vibrato and a slightly fragile delivery; Mood: The specific silence after a phone call you didn't want to end, just the faint hum of the empty line; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Intimate, minimalist aesthetic. Vocals are front/center with spacious reverb. Pronounced low-mids for warmth, rolled-off highs; Highlight: The single beat of dead air after a melodic phrase, where the ukulele stops and the vocal re-enters alone, shifting the emotional tone from longing to quiet accusation.",
  "title": "便利贴",
  "lyrics": "[intro]\n(Mix: Intimate, warm, lo-fi aesthetic. Prominent low-mids, silky rolled-off highs. Vocals sit in a bed of plate reverb. Wide stereo field dominated by a single ukulele panned slightly left.)\n(Inst: Close-mic'd ukulele playing a simple, syncopated chord pattern; audible finger slides and fret noise.)\n(Chords: Am - G - C - F)\n\n[verse]\n(Vocal-Perf: Breathy, almost whispered delivery, pitched low in register. Very close to the microphone.)\n(Melody-Rhythm: Phrases begin lazily after beat one, drifting across the bar line.)\n(Inst: Ukulele continues, joined by a subtle, deep synth pad just filling the sub frequencies.)\n(Chords: Am - G - C - F)\n搬走那天 你的钥匙还挂着\n门缝里塞了张便利贴\n字迹已经泡皱了\n写着以后见\n\n[pre-chorus]\n(Vocal-Perf: Volume increases slightly, a touch more air in the voice. A hint of vulnerability.)\n(Melody-Contour: Gentle stepwise ascending line, building minimal tension.)\n(Chords: Am - G - C - G)\n洗了三遍 还是洗不掉\n你换了洗发水的味道\n\n[chorus]\n(Vocal-Perf: Voice opens up but remains soft. Subtle, low-mixed harmony doubles the main line on key words.)\n(Hook-DNA: Rhythmic motif is a dotted eighth + sixteenth pattern on \"屏幕冰冷的光\"; anchors on the 5th (E); repeats twice, third statement alters rhythm to resolve.)\n(Melody-Contour: Main leap is an ascending perfect 4th on the first beat, creating an emotional lift before descending.)\n(Melody-Harmonic-Tension: Melody holds the major 7th (G#) over the Am chord for a full beat, creating a poignant, unresolved feeling before falling to the root.)\n(Mix: Stereo field widens slightly. Vocal reverb tail becomes more prominent.)\n(Chords: F - C - G - Am)\n那张便利贴 贴在镜子旁\n褪色的字迹 是你最后的模样\n我没撕掉它 只是翻过去放\n让胶面朝外 空白面朝向光\n\n[verse]\n(Vocal-Perf: Returns to the hushed delivery of the first verse.)\n(Inst: A sparse, heavily-reverbed electric piano plays single counter-melody notes, panned hard right.)\n(Chords: Am - G - C - F)\n超市结账 收银机嗡嗡响\n我还是买了两份酸奶\n放到第二格 冷藏\n忘了你不来\n\n[pre-chorus]\n(Vocal-Perf: A touch of vocal fry on the last word, emphasizing resignation.)\n(Melody-Contour: Repeats the same gentle ascending line as the first pre-chorus.)\n(Chords: Am - G - C - G)\n过期了也没扔掉\n只是不敢去检查保质期了\n\n[chorus]\n(Vocal-Perf: More confident than the first chorus. Harmonies are slightly louder in the mix.)\n(Hook-DNA: Rhythmic motif is a dotted eighth + sixteenth pattern on \"屏幕冰冷的光\"; anchors on the 5th (E); repeats twice, third statement alters rhythm to resolve.)\n(Melody-Harmonic-Tension: Melody again holds the major 7th over the Am chord, but this time resolves downwards more quickly, feeling more decisive.)\n(Mix: Electric piano becomes more active. Vocal harmonies are wider.)\n(Chords: F - C - G - Am)\n那张便利贴 贴在镜子旁\n褪色的字迹 是你最后的模样\n我没撕掉它 只是翻过去放\n让胶面朝外 空白面朝向光\n\n[outro]\n(Vocal-Perf: Ad-libbed, wordless vocal line, breathy and fading out.)\n(Inst: Ukulele strums once and lets the chord ring out. Electric piano plays a final, questioning phrase. The synth pad slowly fades.)\n(Mix: All elements are slowly pulled back, leaving only the long reverb tail of the final vocal ad-lib.)\n(Chords: Fmaj7)\n",
