  "lyrics": "[intro]\n(Chords: F#m - D - A - E)\n(Mix: Spacious, reverb-heavy; Piano and guitar upfront)\n(Inst: Clean electric guitar plays a simple, memorable melodic motif over bright piano arpeggios and a soft synth pad foundation.)\n(Vocal-Perf: No vocals)\n\n[verse]\n(Chords: F#m - D - A - E)\n(Mix: Intimate; Vocal and piano focused)\n(Inst: Arrangement thins out to just piano arpeggios and a subtle bass line. No drums.)\n(Vocal-Perf: Soft, breathy, and close-mic'd; mezzo-piano dynamic; conversational rhythm)\n夹克口袋翻出来 是那张没用掉的票\n你说要一起去看 然后就再没有联络\n\n[pre-chorus]\n(Chords: D - E - C#m - F#m, D - E - A)\n(Transition: Simple drum machine beat enters with a soft kick and snare, lifting the energy.)\n(Inst: Piano shifts to simple block chords, bass becomes more prominent.)\n(Vocal-Perf: Builds slightly in volume and intensity; more sustained notes, leading into the chorus)\n日期印在那行小字 早就过了有效期\n我还留着 是因为 舍不得承认已放弃\n\n[chorus]\n(Chords: F#m - D - A - E)\n(Mix: Expands to full width; lush and atmospheric)\n(Inst: The highlight lush synth string pad enters, creating a wide, emotional backdrop. Electric guitar re-enters with subtle arpeggios. Drum beat is steady and supportive.)\n(Vocal-Perf: Stronger, more emotional delivery; mezzo-forte; soaring melody in the upper register)\n如果时间能退票 我愿意排很久的队\n把那个说好却没来的夜 轻轻折叠退回去\n如果眼泪能换到 你回头时一个眼神\n我不要补偿 只想知道你有没有认真\n\n[bridge]\n(Chords: D - E - C#m - F#m, D - E - A)\n(Transition: A brief pause in the drums before the beat re-enters, creating dynamic contrast.)\n(Mix: Instruments pull back slightly to refocus on the vocal question.)\n(Inst: Piano and bass drive the harmony with a slightly different rhythmic feel.)\n(Vocal-Perf: More direct and questioning tone; a moment of vulnerability before the final emotional peak.)\n那条消息我发出去 你已读了三百天\n三百个早晨 我还是不敢删\n\n[chorus]\n(Chords: F#m - D - A - E)\n(Mix: The fullest and widest point of the song; climax)\n(Inst: All elements are present. Synth strings are at their most prominent. Subtle vocal harmonies or doubles are added for thickness.)\n(Vocal-Perf: Most powerful and emotional delivery; ad-libs can be added towards the end; full forte dynamic.)\n如果时间能退票 我愿意排很久的队\n把那个说好却没来的夜 轻轻折叠退回去\n如果眼泪能换到 你回头时一个眼神\n我不要补偿 只想知道你有没有认真\n\n[outro]\n(Chords: F#m - D - A - E)\n(Transition: Music begins a slow fade out.)\n(Inst: Drums and bass drop out, leaving the intro's electric guitar motif playing over the piano arpeggios and fading synth pad.)\n(Vocal-Perf: A final, distant, heavily-reverberated ad-lib of the hook phrase.)\n你有没有认真",
  "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：一张边缘轻微卷曲、颜色泛黄的小纸片，以极度柔焦的方式悬浮在画面中央，四周是从暖米白色向冷灰蓝色缓慢过渡的水彩渐变背景，纸片本身仅以朦胧的矩形轮廓呈现，无任何文字细节，背景隐约透出淡淡的竖向光影，如同透过毛玻璃折射的远光。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。",
