{"status": "success", "json_a": {"prompt": "Genre: Mandopop / Pop-Rock; BPM: 150; Key: G# Major; Rhythm: Half-time rock groove (75 BPM feel) with driving 16th-note hi-hats. Kick on 1 & 3, powerful snare on 2 & 4.; Instruments: Clean grand piano arpeggios/chords, punchy modern drum kit, round electric bass, layered clean/distorted electric guitars, lush background synth pads.; Vocals: Male tenor, clear and emotive. Shifts from a gentle chest voice in verses to a powerful, strained belt in the choruses. Polished with hall reverb.; Mood: The deafening silence after hanging up the phone, the words you didn't say echoing in a cold, empty room.; Production: High-fidelity, radio-ready polish. Dynamic mix with intimate verses and a wide, layered chorus. Clear vocals.; Language: Mandarin; Highlight: The explosive downbeat of the first chorus, where the full rock band crashes in after a sparser verse, creating a sudden wall of sound.", "lyrics": "[intro]\n(Chords: C#maj7 - G#/C - A#m7 - D#sus4)\n(Inst: Clean piano playing a gentle, arpeggiated motif. Subtle synth pads swell underneath, creating a sense of anticipation.)\n(Mix: Narrow and intimate, setting a melancholic tone.)\n\n[verse]\n(Chords: G# - D#/G - Fm7 - C#maj7)\n(Vocal-Perf: Soft, breathy chest voice; conversational and close-mic'd. Mezzo-piano.)\n(Inst: Piano provides sparse chordal support. A simple kick and clap pattern enters halfway through, establishing the rhythm.)\n(Mix: Vocals are dry and upfront, creating an intimate, confessional feel.)\n从不主动示弱\n我们的过去\n分分合合太多\n伤人的话难说\n却觉得很洒脱\n曾经的那些发生过的开心和难过\n\n[pre-chorus]\n(Chords: C#maj7 - G#/C - A#m7 - D#)\n(Vocal-Perf: Builds slightly in intensity, moving from conversational to more melodic and sustained. A touch of yearning.)\n(Inst: The drum beat becomes more consistent. Clean electric guitar arpeggios add a layer of texture.)\n(Transition: A subtle cymbal swell and a pause for breath right before the chorus hits.)\n就像开败的花\n浪也拍打着沙\n我却对你情有独钟\n我陪你留下\n说最浪漫的话\n即便是青春的懵懂\n\n[chorus]\n(Chords: G# - D#/G - Fm - D# - C# - G#/C - A#m7 - D#)\n(Vocal-Perf: Erupts into a powerful, high-register belt; emotive and strained. Mezzo-forte.)\n(Inst: Full band crashes in. Heavy distorted rhythm guitars create a wall of sound. The bass is driving and the drums are powerful and open.)\n(Mix: Expands into a wide, cinematic stereo field. The dynamic shift is sudden and impactful.)\n我不知为何\n疯狂对你执着\n我们之间的故事还不多\n这回忆的漩涡\n快要把我吞没\n求你别离开我\n因为\n我欠你太多\n手松开的沉默\n连着我这颗心也死了\n对于你是解脱\n而我如此落魄\n求你别离开我\n\n[bridge]\n(Chords: C# - D# - Cm7 - Fm - C# - G#/C - A#m7 - D#sus4 - D#)\n(Vocal-Perf: Starts reflectively, then builds to a desperate, almost raw plea. The highest and most intense vocal moment.)\n(Inst: Instruments pull back slightly at the beginning, featuring piano and vocals, then build with layered guitars and powerful drum fills.)\n(Mix: Starts narrower and builds back to the full width of the chorus.)\n(Transition: A sustained vocal note hangs over a drum fill, crashing directly into the final chorus.)\n我拼了命的隐藏着痛\n努力微笑想让你回头\n被泪水打湿的是一场梦\n我在掩饰我的执着\n爱还会不会回来\n这是我的独白\n\n[chorus]\n(Chords: G# - D#/G - Fm - D# - C# - G#/C - A#m7 - D#)\n(Vocal-Perf: Maximum power and desperation. Layered with harmony vocals and ad-libs, adding to the epic scale. Forte.)\n(Inst: All elements at their peak. Lead guitar lines weave around the vocal. Cymbals are crashing frequently.)\n(Mix: The widest and loudest point of the song. A dense, emotional wall of sound.)\n我不知为何\n疯狂对你执着\n我们之间的故事还不多\n这回忆的漩-涡\n快要把我吞没\n求你别离开我\n因为\n我欠你太多\n手松开的沉默\n连着我这颗心也死了\n对于你是解脱\n而我如此落魄\n求你别离开我\n\n[outro]\n(Chords: C#maj7 - G#maj7 - Fm7 - G#)\n(Inst: The full band cuts out, leaving only the original piano motif playing over a sustained pad. A final, clean guitar harmonic echoes.)\n(Mix: Abruptly returns to the narrow, intimate space of the intro.)\n(Structure: Fade out on the last piano chord, letting the reverb tail decay into silence.)"}, "time": 43.7, "attempt": 2, "prompt_ok": true, "lyrics_ok": true, "api": "official", "provider": "google", "model": "gemini-2.5-pro", "usage": {"prompt_tokens": 13059, "completion_tokens": 1305, "total_tokens": 17267}}
