  "prompt": "Genre: Cinematic Dream Pop; BPM: 112; Key: F# minor; Rhythm: Driving half-time groove with a heavy, reverberant kick on 1 and a layered snare/clap on 3, creating a grand, slow-motion feel.; Instruments: Grand piano arpeggios, cinematic string section, deep sub-bass synth, programmed epic drums, atmospheric synth pads; Vocals: Female, languid and breathy low-register verses with vocal fry, soaring into an emotive but controlled higher register for the chorus, featuring lush background vocal stacks.; Mood: The feeling of driving fast at dusk with the windows down after a perfect day, knowing it can't be repeated.; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Cavernous reverbs create a vast soundscape with an ultra-wide stereo image.; Highlight: The moment the massive, half-time drums and soaring string orchestra enter simultaneously on the first full chorus, transforming the melancholic theme into a cinematic epic.",
  "title": "候鸟不回头",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix. Wide stereo image, dominated by huge cinematic reverbs. Prominent, clean sub-bass. Punchy drums sit in the mix, not on top. Silky, controlled high-end.)\n(Inst: Melancholic grand piano arpeggio. Distant, repeating bell synth motif. Soft, lush string pads swelling.)\n(Chords: F#m - A - E - Bm)\n(Hook-DNA: Bell synth plays repeating 'G#-F#-E' motif, dotted eighth + sixteenth rhythm, anchoring the melancholic theme.)\n\n[verse]\n(Vocal-Perf: Low-register, breathy, almost spoken delivery with subtle vocal fry on phrase ends.)\n(Inst: Piano and bells continue. Deep sub-bass synth enters on root notes. Sparse, heavy kick drum begins a half-time pattern.)\n(Melody-Contour: Mostly stepwise motion in a narrow range, creating a plateau of intimacy.)\n(Melody-Rhythm: Phrasing is relaxed and behind the beat, languid and conversational.)\n(Chords: F#m - A - E - Bm)\n旧毛衣叠在衣柜最底层\n你走的那年我忘了放冬天\n\n[pre-chorus]\n(Vocal-Perf: Rises slightly in pitch and intensity, moving from breathy to a more supported, melodic tone.)\n(Inst: A powerful, layered clap/snare enters on beat 3. String section swells dramatically. Arpeggiated harp-like synth adds rhythmic energy.)\n(Transition: Clear dynamic build towards the chorus.)\n(Chords: F#m - A - E - Bm - D - A - E - E)\n候鸟飞过屋顶那条缝\n像极了你侧脸离开时的弧\n我把窗帘拉得死死的\n假装正午的光不刺眼\n出门前贴着门框站了一分钟\n外卖袋的塑料音还在耳边\n巷口便利店门铃叮了两声\n世界好安静 安静到吓人\n\n[chorus]\n(Mix: Explosive dynamic shift. Stereo image widens dramatically. Parallel compression on drums for maximum impact. Strings and layered vocals dominate.)\n(Vocal-Perf: Soars into a higher, emotive register. Lush background vocal stacks enter with harmonies and atmospheric 'oohs'.)\n(Inst: Full cinematic orchestra and epic drums crash in. Soaring high string counter-melodies. Piano plays powerful block chords.)\n(Hook-DNA: Core phrase \"Summertime sadness\" lands on a descending motif from 3 to 1; The rhythmic chant \"su-su-summertime\" uses syncopated sixteenths, creating a stuttering, infectious rhythm; Motif repeats with increasing vocal layers.)\n(Melody-Contour: Dramatic ascending leap of a minor 6th on \"Kiss me hard\", creating an emotional arch shape.)\n(Melody-Harmonic-Tension: Melody on \"sadness\" resolves powerfully to the tonic (F#) over the F#m chord. The post-chorus chant creates tension by repeating the tonic and 5th over shifting harmony.)\n候鸟不回头 候鸟不回头\n飞过我这片 已经入秋的屋顶\n我还站在这 候鸟不回头\n把你给的温度 还给了南方\n候鸟 候鸟 候鸟不回头\n候鸟 候鸟 候鸟不回头\n候鸟不回头\n\n[verse]\n(Mix: Energy drops, but the full drum loop continues at a lower volume, maintaining momentum.)\n(Vocal-Perf: Returns to the lower, intimate delivery, but with more forward motion than the first verse.)\n(Inst: Arrangement thins out to piano, bass, and drums. Strings become subtle pads.)\n(Chords: F#m - A - E - Bm)\n冰箱贴还是你买的那块磁铁\n上面的字褪到只剩一个轮廓\n我用手指描了一遍又一遍\n像在读一封寄不出去的信\n\n[bridge]\n(Mix: Stripped back. Focus on the vocal, piano, and reverb tails. Drums become very sparse.)\n(Vocal-Perf: Becomes airy and ethereal, floating in a higher register.)\n(Inst: Strings hold long, sustained notes. Piano plays simple, spaced-out chords. Drums drop out, leaving a single kick.)\n(Chords: D - A - E - F#m - D - A - E - E)\n(Melody-Harmonic-Tension: Melody deliberately avoids the tonic, hanging on the 3rd and 5th over the subdominant (D) and dominant (E) chords, creating a feeling of suspension and unresolved longing before the final chorus.)\n也许迁徙本来就没有方向\n也许停留才是最难的事\n我学不会候鸟那种坦荡\n所以我还在这里 等着你\n\n[chorus]\n(Mix: Maximum energy and width. Additional vocal ad-libs and harmonic layers are added for the final climax.)\n(Vocal-Perf: Most powerful and desperate delivery of the song. Ad-libs weave through the background vocal stacks.)\n(Inst: All instrumental elements at full force. String section plays its most dramatic and soaring lines.)\n候鸟不回头 候鸟不回头\n飞过我这片 已经入秋的屋顶\n我还站在这 候鸟不回头\n把你给的温度 还给了南方\n候鸟 候鸟 候鸟不回头\n候鸟 候鸟 候鸟不回头\n候鸟不回头\n\n[outro]\n(Mix: Instruments begin to filter out. High frequencies roll off. The sound becomes more distant.)\n(Vocal-Perf: The repetitive chant of the hook fades out slowly, drenched in reverb and delay.)\n(Inst: Drums and strings fade first, leaving piano and the bell motif, which then fade to silence, leaving only the vocal reverb tail.)\n候鸟 候鸟 候鸟不回头\n候鸟 候鸟 候鸟不回头",
