  "lyrics": "[intro]\n(Chords: C - G/B - Am - Am/G - F - C/E - Dm7 - G7)\n(Inst: Solo grand piano playing a memorable, arpeggiated motif with heavy reverb. Gentle string pads swell in the background.)\n(Mix: Piano centered, strings creating a wide stereo field.)\n\n[verse]\n(Chords: C - G/B - Am - Am/G - F - C/E - Dm7 - G7)\n(Vocal-Perf: Gentle, breathy chest voice; intimate and close-mic'd; mezzo-piano.)\n(Inst: Piano continues arpeggios, supported by a subtle, round electric bass. Very sparse percussion, maybe a single rim click on the backbeat.)\n(Mix: Vocals are dry and upfront, creating an intimate feel.)\n冰箱上贴着你写的字条\n四月的日期已经泛了黄\n我没舍得撕却也没勇气瞧\n习惯了你走后这房间的凉\n衣架上还挂着你那件旧外套\n我绕着它转不敢往前闯\n\n(Transition: String section swells subtly in volume, leading into the next verse. A soft kick drum pattern begins.)\n\n[verse 2]\n(Chords: C - G/B - Am - Am/G - F - C/E - Dm7 - G7)\n(Vocal-Perf: Intensity builds slightly but remains controlled; still in chest voice.)\n(Inst: Strings become more present with long, sustained notes. The simple drum beat continues.)\n(Mix: The sonic space starts to open up, preparing for the chorus.)\n手机备忘录里你名字靠前\n我一次次滑过却不敢点\n想删去的话攒了整整一年\n指尖悬着 最后没有按\n灶台上的盐还是你买的那袋\n快见底了 我一直在省着用完\n\n(Transition: A powerful string swell and a simple drum fill (snare roll) launches into the chorus.)\n\n[chorus]\n(Chords: F - G - Em - Am - Dm7 - G - C - C7)\n(Vocal-Perf: Full, powerful chest voice; mezzo-forte; longer, sustained notes.)\n(Inst: The full orchestral string section enters with a dramatic, soaring counter-melody. The piano plays strong block chords. Full drum kit provides a solid, simple backbeat.)\n(Mix: Very wide stereo image; vocals cut through the dense instrumentation. Lush hall reverb on all elements.)\n你走了以后 我还住在这里\n白板上你写的格子一个没擦去\n那些空着的计划等谁来填\n我不知道 也不愿意提\n你走了以后 我只学会压抑\n把思念压进每一件没用的琐事里\n灯亮着 饭做着 门开着\n可回来的只剩我自己\n\n(Transition: The full band cuts out, leaving only the reverberant strings and piano to lead into the instrumental section.)\n\n[interlude]\n(Chords: F - C/E - Dm7 - G - C)\n(Inst: A soaring, emotive melody played by the lead violins over the piano's chordal accompaniment. No vocals, no drums.)\n(Mix: The string section is the absolute focus, very wide and cinematic.)\n\n(Transition: The full band crashes back in for the final chorus.)\n\n[chorus]\n(Chords: F - G - Em - Am - Dm7 - G - C - C7)\n(Vocal-Perf: The most powerful and emotional delivery of the song; potential for a slight vocal crack or strain to convey desperation. Forte.)\n(Inst: All instruments play at their peak intensity. Crash cymbals accent the downbeats. The string arrangement is at its most complex and powerful.)\n(Mix: Maximum dynamic range and width. Vocals feel epic and cathartic.)\n你走了以后 我还住在这里\n白板上你写的格子一个没擦去\n那些空着的计划等谁来填\n我不知道 也不愿意提\n你走了以后 我只学会压抑\n把思念压进每一件没用的琐事里\n灯亮着 饭做着 门开着\n可回来的只剩我自己\n\n(Transition: The final chord is held by the strings and piano, then slowly fades out.)\n\n[outro]\n(Chords: F - C/E - Dm7 - C)\n(Inst: The solo piano returns, playing a fragment of the intro motif. It resolves on a final, single C major chord that rings out with a long reverb tail.)\n(Sound-Design: The sound of the piano's sustain pedal releasing at the very end.)",
  "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：一块接近正方形的白色磁性白板，占据画面中央偏左的位置，白板表面有几条用细马克笔画出的浅灰色格子线，格子大部分空白，只有一个格子里有一个笔迹轻淡、即将消散的小小叉号；白板边缘泛着极微弱的冷光，背景是一片深邃的暖灰色，像一堵旧公寓的水泥墙。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。",
