  "lyrics": "[intro]\n(Chords: Abm - E - B - Gb)\n(Mix: Vocals filtered with delay, sparse electric piano melody)\n(Vocal-Perf: Breathy, whispered delivery, establishing an intimate and melancholic tone)\n(Melody-Dev: A cappella-like vocal hook sets up the main theme immediately)\n折好放在最里面\n每次搬家都带着走\n说不清楚为什么\n就是舍不得\n\n[verse]\n(Chords: Abm - E - B - Gb)\n(Transition: Filter on vocal opens up, soft sub-bass and a simple kick/snap beat enter)\n(Inst: Electric piano carries the harmony with simple chord voicings)\n(Vocal-Perf: Clear, conversational, storytelling style.

Clear and direct delivery of the hook)\n你留下的那件毛衣\n我一直没舍得洗\n像是怕洗掉了什么\n就真的和你没关系\n你留下的那件毛衣\n叠在衣柜最底\n每次冷了我都不敢碰\n因为一碰就想哭泣\n\n[verse 2]\n(Chords: Abm - E - B - Gb)\n(Transition: Arrangement thins out, pads recede)\n(Inst: Beat and bass remain, but feel softer, creating dynamic contrast with the chorus)\n(Vocal-Perf: Returns to the intimate, reflective tone of the first verse)\n新认识的人问我喜欢什么颜色\n我说不上来 停顿了一下\n想起你总穿那件灰蓝\n说这颜色最耐看\n现在路上撞见同款\n我都要低下头走完\n\n[chorus]\n(Chords: E - B - Abm - Gb)\n(Mix: The fullest and most emotionally resonant section. All elements are present and at their peak dynamic level)\n(Inst: A subtle arpeggiated synth melody might be added for texture)\n(Vocal-Perf: Most powerful and open delivery, especially on sustained notes, while maintaining clarity)\n你留下的那件毛衣\n我一直没舍得洗\n像是怕洗掉了什么\n就真的和你没关系\n你留下的那件毛衣\n还带着你的气息\n我知道该放手了 但是\n就是做不到忘记\n\n[outro]\n(Chords: Abm - E - B - Gb)\n(Transition: Beat and bass fade out, leaving piano and vocals)\n(Inst: Electric piano plays a simple, resolving arpeggio as it fades)\n(Vocal-Perf: Final line delivered softly, fading into reverb)\n就是做不到忘记",
  "cover_prompt": "生成一张极简主义（Minimalist）插画和阴影艺术（Shadow art）风格的艺术图片作为无字音乐专辑封面。画面的核心是一件浅灰蓝色的针织毛衣整齐叠放在木质层架上，毛衣边缘轮廓柔和，光线从侧面斜入，将层架横条的细长影格投射在毛衣表面，形成安静而忧郁的条纹光影。整个投影区域具有淡黄米色、带颗粒感的纹理，类似于旧丝网印刷（Screenprint），赋予画面一种褪色的温柔怀旧感。背景是一个极淡的雾蓝灰色实色区域，带有微妙的冷调纹理，与毛衣的灰蓝形成同色系的层次感。构图干净、宁静且优雅。强烈要求：这是一张纯粹的、极简主义、治愈系插图，绝对不要出现具体的五官、现代工业物品或3D渲染效果！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！传达出一种宁静、舒适、怀旧且梦幻的艺术气息。",
