  "prompt": "Genre: Mandopop / Pop Ballad; BPM: 166; Key: F# Major; Rhythm: Slow, emotional half-time pop groove at 83 BPM feel. Kick on 1 & 3, clean snare on the backbeat. Ticking 16th-note hi-hats provide subtle drive, creating a floating, expansive feel.; Instruments: Arpeggiated grand piano, warm acoustic guitar textures, atmospheric clean electric guitar swells with delay, round supportive electric bass, modern pop drum kit; Vocals: Female; Clear, breathy, and emotive mid-to-high range voice with a delicate head-voice. Gentle, conversational verses build to a powerful, sustained chorus. Processed cleanly with subtle reverb for a polished, intimate sound.; Mood: Watching the last train pull away from the platform on a cold, damp evening, the station lights blurring through unshed tears.; Highlight: The downbeat of the first chorus (0:58) where the full band and soaring strings enter suddenly under the lifted vocal melody, creating an expansive, heart-wrenching emotional release.",
  "lyrics": "[intro]\n(Chords: F# - C#/F - D#m - B)\n(Inst: Ethereal synth pads, clean piano melody playing the main motif.)\n(Mix: Wide and spacious, setting a reflective tone.)\n\n[verse]\n(Chords: F# - C#/F - D#m - B)\n(Inst: Piano continues, subtle acoustic guitar arpeggios enter. Clean bass guitar enters halfway through with simple root notes.)\n(Vocal-Perf: Gentle, breathy, conversational tone, mezzo-piano dynamic.)\n(Mix: Vocals are intimate and centered.)\n(Transition: Light cymbal swell builds anticipation.)\n如果离别是为了能再见一面\n爱是想念后的抛物线\n离开始 渐行渐远 和我们 总是擦肩\n这次再见如果是最后的一面\n也是失眠后的分割线\n春天已 开始落叶 七月里 也会下雪\n\n[chorus]\n(Chords: B - F#/A# - G#m - C#)\n(Inst: Full pop drum kit enters with a steady half-time groove. Soaring string section provides a lush, emotional backdrop. Bass is solid and foundational.)\n(Vocal-Perf: Stronger, more sustained chest voice, mezzo-forte, conveying a sense of longing.)\n(Mix: Expands into a wide stereo image, strings fill the space, drums punch through the center.)\n(Transition: The final chord hangs with reverb before a clean cut into the next section.)\n刚刚我错过的大雨  握不住的盛夏\n飘过的云是你吗 一圈又一圈\n我多想是路过你的风 忍不住落回你眼中\n凭什么绕不开 翻不过的盛夏\n有些远方 让风代替我们抵达\n没勇气说完的那句话 希望有人听过它\n\n[verse]\n(Chords: F# - C#/F - D#m - B)\n(Inst: Drums simplify to a kick and hi-hat pattern. Strings pull back to soft, sustained pads. Piano remains the core element.)\n(Vocal-Perf: Returns to a softer, more reflective delivery, but with more forward momentum than the first verse.)\n(Mix: Narrows slightly to refocus on the vocal intimacy.)\n这次再见如果是最后的一面\n也是失眠后的分割线\n春天已 开始落叶 七月里 也会下雪\n\n[bridge]\n(Chords: G#m - D#m - E - C#)\n(Inst: Arrangement strips back to piano, atmospheric guitar swells, and bass. Strings hold a single, tense high note.)\n(Vocal-Perf: Builds in intensity from a near-whisper to a powerful plea, leading directly into the final chorus.)\n(Melody-Contour: Ascending line creating tension and release.)\n(Transition: A powerful drum fill and cymbal crash launches into the final chorus.)\n让你听见风缓缓地 缓缓摇曳\n时光卷起了回忆慢慢翩翩\n让风替我说 说那句告别\n在这个落叶像雪的季节\n\n[chorus]\n(Chords: B - F#/A# - G#m - C#)\n(Inst: The most powerful section. All instruments playing at full intensity. String section plays an soaring counter-melody. Cymbals crash on downbeats.)\n(Vocal-Perf: Peak emotional delivery, powerful and sustained, with subtle ad-libs and harmonies layered.)\n(Mix: Maximum width and depth, a true cinematic climax.)\n刚刚我错过的大雨 握不住的盛夏\n飘过的云是你吗 一圈又一圈\n我多想是路过你的风 忍不住落回你眼中\n凭什么绕不开 翻不过的盛夏\n有些远方 让风代替我们抵达\n没勇气说完的那句话 希望有人听过它\n\n[outro]\n(Chords: B - F# - G#m - F#)\n(Inst: Deconstructs the arrangement, fading out with the main piano motif and the lingering tail of the string section.)\n(Mix: Slowly fades to silence, leaving just the piano reverb.)\n(Structure: Instrumental fade out.)",
