  "prompt": "Genre: Mandopop Ballad; BPM: 130; Key: Bb Major; Rhythm: Mid-tempo pop-rock beat with a strong half-time feel, snare on beat 3. Straight 8th-note hi-hats provide drive. Simple kick and bass foundation.; Instruments: Clean electric guitar playing arpeggios, acoustic guitar strumming, digital piano chords, synthesized string pads for atmosphere. A melodic, distorted electric guitar enters in the chorus for power and plays an emotional solo.; Vocals: Male tenor, clear and earnest, with a characteristic emotional strain in the high-register chorus. Syllabic, direct delivery with natural vibrato on sustained notes.; Mood: Heartbroken and regretful, centered on the emotional archetype of farewell (送别) and nostalgic what-ifs after a breakup.; Highlight: the powerful, emotionally-strained male tenor vocal in the anthemic chorus.",

  "lyrics": "[intro]\n(Chords: Bb - Gm - Eb - F)\n(Inst: Clean electric guitar arpeggio with delay, gentle piano chords establish a melancholic mood.)\n(Mix: Intimate, setting the stage for vocals.)\n\n[verse]\n(Chords: Bb - Gm - Eb - F)\n(Inst: Full band enters subtly. Acoustic guitar strumming, simple bass line on root notes, soft drum beat with hi-hats.)\n(Vocal-Perf: Conversational and clear tenor voice, slightly restrained, every syllable articulated.)\n(Melody-Contour: Gentle, stepwise motion, setting up the story.)\n那天你站在出租屋门口背着包\n说要去更远的地方 不打算回头\n我数着你给我发来的最后那条消息 才明白\n有些人的离开 不需要理由\n\n[chorus]\n(Transition: Drum fill and cymbal crash lift the energy.)\n(Chords: Eb - F - Gm - Bb - Eb - F - Bb)\n(Inst: Energy lifts significantly. Distorted electric guitar plays power chords. Lush synth strings swell in the background.)\n(Vocal-Perf: Voice shifts to a powerful, higher-register chest mix. Pronounced emotional strain and vibrato on long notes. Anthemic and memorable.)\n(Melody-Contour: Wide interval leap to the peak note, highly singable hook.)\n我以为我学会了不在乎 原来只是骗自己\n越是假装洒脱 越是透骨的伤\n早知道 早知道就不该学会不在乎\n那些没说出口的 都成了心里的刺\n我以为放开手就能不在乎 哪有那么容易\n你走的那一步 让我后退了好几年\n早知道 早知道就死死抓住不放手\n\n[verse]\n(Transition: Energy drops back down smoothly.)\n(Chords: Bb - Gm - Eb - F)\n(Inst: Rhythm section simplifies, distorted guitar drops out, clean electric guitar arpeggios return.)\n(Vocal-Perf: Returns to a more narrative, restrained delivery, carrying the emotion from the chorus.)\n后来我把你的联系方式存在草稿箱\n发过去又删掉 删掉又打开\n周围人都说时间会把一切磨平\n可时间越久 那个缺口越大\n\n[chorus]\n(Transition: Powerful drum fill leads back into the high-energy section.)\n(Chords: Eb - F - Gm - Bb - Eb - F - Bb)\n(Inst: Full band at maximum energy. Distorted guitar and strings are prominent.)\n(Vocal-Perf: Peak emotional delivery, strained and powerful high notes, full-throated singing.)\n(Mix: Wide, full, and powerful. Vocals cut through clearly.)\n我以为我学会了不在乎 原来只是骗自己\n越是假装洒脱 越是透骨的伤\n早知道 早知道就不该学会不在乎\n那些没说出口的 都成了心里的刺\n我以为放开手就能不在乎 哪有那么容易\n你走的那一步 让我后退了好几年\n早知道 早知道就死死抓住不放手\n\n[interlude]\n(Chords: Eb - F - Gm - Bb - Eb - F - Bb)\n(Inst: Melodic and emotional electric guitar solo takes the lead. The solo follows the vocal contour of the chorus, using bends and vibrato. Strong backing from the rhythm section and string pads.)\n(Sound-Design: Guitar tone has sustain and a touch of delay.)\n\n[chorus]\n(Transition: Solo seamlessly flows back into the final vocal chorus.)\n(Chords: Eb - F - Gm - Bb - Eb - F - Bb)\n(Inst: All elements at full force for the final climax.)\n(Vocal-Perf: The most intense vocal performance, with slight ad-libbed emphasis but maintaining clarity. Sustains the final note with strong vibrato.)\n我以为我学会了不在乎 原来只是骗自己\n越是假装洒脱 越是透骨的伤\n早知道 早知道就不该学会不在乎\n那些没说出口的 都成了心里的刺\n放开手真的就能不在乎吗 我不信\n你走的那一步 是我这辈子最贵的错\n早知道 早知道就死死抓住 不放手\n\n[outro]\n(Chords: Eb - F - Bb)\n(Inst: Band plays a final chord and holds it. A clean electric guitar plays a final, fading arpeggio echoing the intro motif.)\n(Mix: Begins a slow fade to silence.)",
