  "prompt": "Genre: Anime Pop-Rock Ballad; BPM: 132; Key: F Major; Rhythm: Half-time pop-rock groove in verses, building to an anthemic 8th-note rock backbeat in choruses.; Instruments: Grand piano (arpeggios/chords), punchy acoustic drums, clean electric bass, layered strings (pads/swells), and subtle overdriven electric guitars.; Vocals: Female, clear, emotive, and breathy voice with a youthful timbre. Gentle verses rise to a powerful, soaring belt in the chorus with controlled vibrato.; Mood: Watching home movies on a dusty projector, the light's warmth mixing with the chill of an empty room.; Production: Polished cinematic mix with high-fidelity clarity and analogue warmth. Vocals upfront in lush reverb.; Language: Chinese; Highlight: The sudden explosion of the full rock band and orchestra on the downbeat of the final chorus, following the intimate and questioning piano-vocal bridge.",
  "title": "旧胶卷",
  "lyrics": "[intro]\n(Chords: Dm - Bb - F - C)\n(Inst: Solo grand piano playing a gentle, arpeggiated motif. Sets a reflective tone.)\n(Mix: Intimate, narrow stereo field, focused on the piano.)\n\n[verse]\n(Chords: Dm - Bb - F - C)\n(Vocal-Perf: Soft, breathy, mezzo-piano delivery. Conversational rhythm.)\n(Inst: Piano continues as main support. A soft string pad enters.)\n(Transition: A simple piano chord hangs before the pre-chorus.)\n奶奶的围裙搭在椅背上\n厨房里飘出的蒸汽还有余温\n我站在走廊 光线斜进来\n照见那些再回不去的下午\n\n[pre-chorus]\n(Chords: Gm - C - Am - Dm - Gm - C)\n(Vocal-Perf: Volume and intensity begin to build. Clearer, more sustained notes.)\n(Inst: Strings swell. Bass enters with simple root notes. Light cymbal taps introduce rhythm.)\n(Transition: Cymbal swell and a simple drum fill leads into the chorus.)\n时间把所有轻的东西都压进了地底\n只有你的笑 还浮在我眼前\n\n[chorus]\n(Chords: F - C - Dm - Bb)\n(Vocal-Perf: Powerful, soaring mezzo-forte chest voice. Emotional emphasis on key words.)\n(Inst: Full band enters. Driving acoustic drums with a clear backbeat, bass provides a solid foundation, strings play a grand, sweeping melody.)\n(Mix: Wide stereo image. Vocals sit powerfully in the center.)\n(Sound-Design: The whole arrangement blooms, creating an epic, cinematic feel.)\n我把你的声音藏在旧胶卷里\n怕哪天连气味也忘干净\n失去的人不会真正消失\n只是躲进我们数过的那片星里\n愿这场雨不要停太早\n让我再淋一次你的从前\n\n[verse]\n(Chords: Dm - Bb - F - C)\n(Vocal-Perf: Returns to a softer, more narrative tone, but with more confidence than the first verse.)\n(Inst: The energy pulls back to piano, bass, and a simpler drum beat. Strings hold long, gentle notes.)\n(Transition: The final line is sung with a slight pause, leading into the bridge's emotional shift.)\n翻出一件洗得发白的旧毛衣\n袖口的线头 你打过结\n我学着你的样子绕了三圈\n才明白 有些手艺不能只靠记忆\n\n[bridge]\n(Chords: Am - Bb - C - F - Am - Bb - C)\n(Vocal-Perf: Starts intimately, almost a whisper, builds with desperation. A slight vocal crack on \"love\".)\n(Inst: Stripped back to just piano and vocal. The piano plays sparse, questioning chords. Strings re-enter and swell dramatically at the end.)\n(Melody-Dev: The melody climbs higher, increasing tension.)\n我不知道 怎么告别才算是告别\n你走的那天 锅里的粥还在滚\n我喝完了 才哭\n哭完了 才懂\n所谓爱 是在你还在的时候\n没把话说清楚\n现在每次开口 都是说给空气听的独白\n可我还是要说 你教会我的 我都记得\n\n[chorus]\n(Chords: F - C - Dm - Bb)\n(Vocal-Perf: Maximum emotional intensity and volume. Fortissimo. The highest notes of the song are here.)\n(Inst: The full band and orchestra crash in on the downbeat. Drums are powerful with heavy cymbal crashes. Overdriven guitar adds texture.)\n(Mix: The biggest, widest point of the song. Everything is layered for a massive wall of sound.)\n(Transition: A powerful drum fill launches the section.)\n我把你的声音藏在旧胶卷里\n怕哪天连气味也忘干净\n失去的人不会真正消失\n只是躲进我们数过的那片星里\n愿这场雨不要停太早\n让我再淋一次你的从前\n你给过我的 都还长在我身上\n\n[outro]\n(Chords: F - C - Dm - Bb - F)\n(Inst: All instruments fade out except for the solo piano, which reprises the intro motif.)\n(Mix: The wide space collapses back to the intimate sound of the intro.)\n(Structure: Music slowly decelerates and fades to silence on a final, sustained F major chord.)",
  "cover_prompt": "生成一张极简主义的几何光影艺术图片作为无字音乐专辑封面。画面的核心是：一卷半展开的旧胶卷，轮廓模糊如水彩晕染，浸泡在从深琥珀到灰蓝的渐变色调中，胶卷上隐约透出柔和的长方形光块，像是被时光漂白的影像残影，背景是带有古旧纸张肌理的米白底色，光与影在胶卷边缘形成极轻柔的交错。画面必须展现出微妙的高级材质肌理，特别是类似水彩晕染（Watercolor texture）或粗糙艺术纸张的触感。整体构图极度克制、留白（Minimalistic composition），注重光与影的柔和交错（Light and shadow interplay）。强烈要求：画面必须保持极致的安宁与静谧（Calm and serene），除了基础的、柔焦的简单几何图形（如模糊的圆、半透明的方块或柔和的线条）外，绝对不要出现任何复杂的现实物体、风景或人物！画面必须是无字封面，绝对不要生成任何文字、拼音或英文字母！绝对不要生成人物轮廓。传达出一种充满诗意、呼吸感与冥想空间的视觉感受。",
