  "prompt": "Genre: Acoustic Folk-Pop Ballad; BPM: 143; Key: C# Major; Rhythm: Sparse, half-time ballad groove (kick on 1, snare on 3) with a gentle, fingerpicked acoustic guitar providing sixteenth-note momentum.; Instruments: Close-mic'd acoustic guitar, finger squeaks audible; Clean electric guitar, glassy ambient lead; Simple drum machine, soft kick & clap; Unobtrusive electric bass, clean tone.; Vocals: Multiple Male Vocals, ranging from intimate close-mic tenor to strained emotional falsetto, with a raw, breathy delivery.; Mood: The quiet hum of a refrigerator at 3 AM, scrolling through old photos on a phone you know you shouldn't be looking at.; Highlight: The first long, sustained note of the electric guitar solo in the bridge, hanging over the sparse chords with a touch of vibrato, wordlessly crying out the song's central regret.",
  "title": "磁带边",
  "lyrics": "[verse]\n(Mix: Intimate, centered mix. Vocals dry and upfront with light plate reverb. Wide stereo acoustic guitar. Warm low-mids, controlled highs. Minimal bus compression, preserving dynamics.)\n(Inst: Close-mic'd steel-string acoustic, fingerpicked arpeggios, fret noise audible.)\n(Vocal-Perf: Breathy, gentle male tenor, vulnerable and close to the mic.)\n(Chords: C# - G# - A#m - F#)\n衬衫还叠在第二个格子里\n你惯用的牙刷换了颜色\n我以为时间能帮我把你风干\n结果只是把思念压进了褶皱里\n隔壁住进了新的租客\n锅铲碰碗的声音\n让我分了神\n\n[chorus]\n(Mix: Drum machine enters, adding weight to the center. Vocal harmonies subtly widen the stereo field.)\n(Inst: Acoustic guitar shifts to light strumming. Soft drum machine (kick on 1, clap on 3). Subtle bass root notes.)\n(Vocal-Perf: Intensity increases to an emotional, strained chest voice. Backing harmonies enter.)\n(Chords: F# - C# - G# - A#m)\n(Hook-DNA: Core motif is two quarter notes on the title phrase, landing on beat 1 & 2, followed by a rest; anchors on the 5th and 3rd; repeats twice before a longer concluding phrase.)\n(Melody-Contour: Ascending arch, peaks with a leap of a major 3rd, resolves downwards.)\n(Melody-Rhythm: Phrases start directly on beat 1, deliberate and on the grid.)\n(Melody-Harmonic-Tension: Melody holds the 3rd over the IV chord creating a stable, yearning feel, before a stepwise descent to the root over the I chord.)\n那年夏天的磁带\n我们各留了一半\n你那半盘不知道还转不转\n我这半盘卡在那个傍晚\n转了又转\n放了又放\n才明白有些歌只唱给一个人听\n\n[verse]\n(Inst: Drum machine continues its sparse pattern. Acoustic guitar returns to arpeggios.)\n(Vocal-Perf: A second male vocalist takes the lead, timbre is slightly fuller but maintains the strained, emotional delivery.)\n(Chords: C# - G# - A#m - F#)\n你发来的那张旧照片\n拍的是我们中间那块空地\n草长了又黄\n没人再去踩\n我盯着屏幕数了一下像素点\n像数清楚自己有多想你\n却说不出口\n只是发了一个问号\n又删掉了\n\n[chorus]\n(Mix: Vocal harmonies are more prominent and wider in the mix. Overall level lifts slightly.)\n(Inst: Drum beat becomes slightly more active with a ghost-note hi-hat.)\n(Vocal-Perf: Lead vocal is more powerful, with emotional ad-libs layered in the background.)\n(Chords: F# - C# - G# - A#m)\n(Hook-DNA: Core motif is two quarter notes on the title phrase, landing on beat 1 & 2, followed by a rest; anchors on the 5th and 3rd; repeats twice before a longer concluding phrase.)\n(Melody-Harmonic-Tension: Increased vocal power heightens the tension on the IV chord before the resolution on the tonic feels more cathartic.)\n那年夏天的磁带\n我们各留了一半\n你那半盘不知道还转不转\n我这半盘卡在那个傍晚\n转了又转\n放了又放\n才明白有些歌只唱给一个人听\n\n[bridge]\n(Mix: Instruments pull back, creating an open space for the electric guitar solo. Reverb on the guitar is more pronounced.)\n(Inst: Acoustic guitar holds down-strummed chords. Drums simplify. Clean electric guitar enters with a lyrical, melodic solo.)\n(Vocal-Perf: Delivery shifts to a half-spoken, reflective tone before dropping out for the guitar solo.)\n(Chords: F# - C# - G# - A#m)\n(Melody-Harmonic-Tension: The electric guitar solo creates tension by holding long, bent notes (e.g., the ♭7) over major chords, delaying resolution and mimicking a pained vocal line.)\n我把你常坐的那把椅子\n转了个方向朝窗\n不是因为采光变好了\n是因为背对着它\n胸口没那么烫\n\n[outro]\n(Inst: All instruments become sparse, fading out on a final, sustained acoustic chord.)\n(Vocal-Perf: Final sung phrase is delivered with a sense of quiet resignation, almost a sigh.)\n(Sound-Design: Final reverb tail of the acoustic guitar fades slowly into silence.)\n有些歌只唱给一个人听",
