  "prompt": "Genre: Mandopop EDM Ballad; BPM: 128; Key: F# major; Rhythm: Driving 4/4 EDM kick drum with off-beat electronic claps and 16th-note hi-hats. Syncopated sawtooth synth bassline locks with the kick.; Instruments: Punchy electronic drum kit (kick, clap, hats). Heavy side-chained synth pads creating a pumping harmonic bed. A bright, arpeggiated sawtooth synth lead for hooks and interludes. Deep sub-bass synth. Clean electric piano for softer sections.; Vocals: Female; clear, youthful female pop vocal, direct and emotional delivery, high-mid range focus, processed with noticeable reverb and delay but remains upfront in the mix.; Mood: Melancholic heartbreak, urban nightclub atmosphere, dance-floor catharsis, expressing sorrow over an energetic beat.; Highlight: The juxtaposition of the melancholic, heartbroken vocal melody against the high-energy, driving EDM beat.",
  "lyrics": "[intro]\n(Chords: B - F# - C# - D#m)\n(Inst: Filtered synth pads, gentle electric piano chords. Ethereal and spacious.)\n(Vocal-Perf: Soft, almost breathy delivery. Clear enunciation. Sets a sorrowful tone.)\n(Mix: Vocals are upfront with heavy reverb. Instruments are distant.)\n无力挽留我的呼喊\n已经淹没在结局里\n心已经被撕碎\n散在空气里飞\n像花朵已枯萎\n无法再次收回\n\n[pre-chorus]\n(Chords: B - F# - C# - D#m)\n(Transition: Rhythmic synth pulse enters, simple kick pattern starts, building tension.)\n(Inst: A rhythmic synth pulse and filtered kick drum enter. Pads swell.)\n(Vocal-Perf: Volume increases slightly. More assertive and pleading tone.)\n从没有让你感觉到快乐\n原谅我心中疯狂的执着\n不要回头看我\n\n[verse]\n(Chords: B - F# - C# - D#m)\n(Transition: Full beat drops with a subtle reverse cymbal.)\n(Inst: Full electronic drum kit (kick, clap, hats) and driving synth bass enter. Side-chain pumping becomes prominent.)\n(Vocal-Perf: Full chest voice, direct and powerful delivery, riding on top of the beat.)\n(Melody-Contour: Rhythmic, conversational phrases landing squarely on the beat.)\n请照顾好自己\n现在说对不起\n曾经有过甜蜜\n为何还要离去\n离开前请结束我的生命\n\n[chorus]\n(Chords: B - F# - C# - D#m)\n(Inst: Bright sawtooth lead synth doubles the main vocal melody or plays a counter-melody. Pads are at their fullest.)\n(Vocal-Perf: Most powerful and emotional delivery. Sustained notes have light, natural vibrato.)\n(Melody-Contour: Ascending line with a leap to a higher peak note for maximum impact. Highly memorable.)\n(Mix: Widest stereo image. Vocals and lead synth dominate.)\n无力挽留我的呼喊\n已经淹没在结局里\n心已经被撕碎\n散在空气里飞\n像花朵已枯萎\n无法再次收回\n\n[post-chorus]\n(Chords: B - F# - C# - D#m)\n(Inst: The lead synth switches to a new arpeggiated pattern. The core rhythm continues.)\n(Vocal-Perf: Delivery becomes slightly more rhythmic and desperate.)\n(Melody-Dev: A new, hooky melodic phrase that complements the main chorus.)\n不要回头看我不要恋恋不舍\n跑着离开我吧以后好好过吧\n眼前你已越来越远\n骗自己让你更远一点\n\n[bridge]\n(Chords: G#m - D#m - B - C#)\n(Transition: Drums simplify to just kick and clap, bassline becomes simpler, holding longer notes.)\n(Inst: Beat thins out. Synth pads are the main focus, with a clean electric piano melody.)\n(Vocal-Perf: More introspective and slightly softer delivery, building back up to the final chorus.)\n(Mix: Less dense, creating dynamic contrast before the final chorus.)\n这么迟钝的我可能有点懦弱\n让你选择逃脱也许这样没错\n忘记所有经过\n宁愿在痛苦中受折磨\n要把回忆慢慢的遗落\n\n[chorus]\n(Chords: B - F# - C# - D#m)\n(Transition: A fast drum fill and filter sweep propel the energy back to its peak.)\n(Inst: Full instrumentation returns. Lead synth is layered and possibly an octave higher for more intensity.)\n(Vocal-Perf: Final, most desperate and powerful performance. Ad-libs with emotional weight but no complex runs.)\n(Mix: The loudest and fullest section of the song.)\n无力挽留我的呼喊\n已经淹没在结局里\n心已经被撕碎\n散在空气里飞\n像花朵已枯萎\n无法再次收回\n\n[outro]\n(Chords: B - F# - C# - D#m)\n(Inst: Music fades out, with the lead synth arpeggio and a final electric piano chord lingering.)\n(Sound-Design: A final, delayed vocal phrase echoes and fades into silence.)\n(Mix: Gradual fade-out over 8 bars, leaving only the reverb tail of the synth.)\n",
