{"status": "success", "json_a": {"prompt": "Genre: Mandopop / Ballad; BPM: 144; Key: C# Major; Rhythm: Slow, piano-led 4/4 groove. Sparse kick on 1, snare on 3. Cymbals swell for emotional emphasis.; Instruments: Resonant grand piano (arpeggios/chords), clean sub bass, simple drum kit (soft kick, wet snare), wide orchestral string pads swelling in choruses.; Vocals: Female. Breathy, intimate verses building to a powerful, clear belt in the chorus. Emotional delivery with controlled dynamics, from whisper to full voice.; Mood: The heavy silence in a car after the fight is over, watching streetlights pass in a blurry daze.; Production: High-fidelity, radio-ready polish. Wide, spacious mix with lush reverb. Vocals centered and upfront.; Language: Mandarin; Highlight: The sudden instrumental drop-out on the first word of the bridge, leaving the lead vocal exposed and vulnerable over a single sustained pad.", "lyrics": "[intro]\n(Chords: F#maj7 - C#maj7 - G#sus4 - G#)\n(Inst: Solo grand piano playing a gentle, arpeggiated motif with spacious reverb.)\n(Mix: Intimate and centered, establishing a melancholic tone.)\n\n[verse]\n(Chords: F# - C# - G# - A#m)\n(Vocal-Perf: Soft, breathy, conversational tone; mezzo-piano; close-mic intimacy.)\n(Inst: Piano continues arpeggios, supported by a warm, low sub-bass.)\n(Mix: Vocal is upfront and relatively dry, creating contrast with the ambient piano.)\n你真的懂唯一的定义\n并不简单如呼吸\n你真的希望你能厘清\n若没交心怎么说明\n\n[chorus]\n(Chords: F# - C# - G# - A#m)\n(Vocal-Perf: Stronger, clearer chest voice; dynamics build to mezzo-forte; more sustained phrasing.)\n(Inst: Simple drum pattern (kick on 1, snare on 3) enters.
