  "lyrics": "[intro]\n(Chords: Dmaj7 - Gmaj7 - Em7 - A7)\n(Inst: Solo digital piano plays arpeggiated, lush chords with heavy, spacious reverb.)\n(Mix: Centered, intimate, establishing the main harmonic theme.)\n\n[verse]\n(Chords: Dmaj7 - Gmaj7 - Em7 - A7)\n(Vocal-Perf: Breathy, soft chest voice, conversational and close-mic'd.)\n(Inst: Piano continues, a deep 808 sub-bass enters on downbeats, and a simple 16th-note hi-hat pattern begins.)\n(Transition: Bass and drums subtly fade in, adding rhythmic foundation.)\n出租屋的墙壁裂了条缝 我一直没修\n就看着它从入秋裂到第二年开春\n有人问我最近在想什么\n我说睡眠不好 省略了后半句\n后来连省略都觉得费力\n点了很多次发送 全删成了已读不—\n不对 是删了没发\n留着也没意义 反正说出来也难以厘清\n\n[chorus]\n(Chords: Dmaj7 - Gmaj7 - Em7 - A7)\n(Vocal-Perf: Stronger, more emotional chest voice with melodic R&B runs. Backing vocals enter.)\n(Inst: Full trap beat with a snappy clap on beat 3. Ethereal female backing vocal pads and synth pads swell to fill the space.)\n(Mix: Stereo field widens significantly. Vocals are layered and lush.)\n这不叫释怀\n叫把伤口摁到皮肤下面去\n久了以后表面看起来平\n可按一下 还是会疼\n我给自己贴了个标签叫「想开了」\n其实只是 懒得再挣扎着呼吸\n\n[verse 2]\n(Chords: Dmaj7 - Gmaj7 - Em7 - A7)\n(Vocal-Perf: Returns to a softer, narrative dynamic after the chorus peak.)\n(Inst: Beat remains consistent, but the pads pull back slightly to refocus on the piano and vocal.)\n(Structure: Acts as a dynamic bridge, linking the emotional chorus to the introspective rap.)\n(Transition: A subtle filter sweep on the hi-hats leads into the next section.)\n冰箱里的东西过期了三周才发现\n不是忙 只是最近眼睛不大往那边看\n朋友约了两次饭 第三次我没回\n不是不想见 是不确定那天脸上挂不挂得住笑\n有时候觉得情绪是个很重的东西\n拎着走 累 放下来 又舍不得丢\n\n[bridge]\n(Chords: Dmaj7 - Gmaj7 - Em7 - A7 loop)\n(Vocal-Perf: Melodic rap flow, syncopated and rhythmically tight, conversational tone.)\n(Inst: The instrumental provides a steady, non-intrusive bed for the rap, with sustained piano chords and the consistent trap beat.)\n(Mix: Rap vocal is brought forward, slightly drier than the sung vocals for clarity.)\n我查过一个词叫「情感隔离」\n说是人在承受不了的时候会自动切断感知\n听起来像自我保护 可我用得太顺手了\n顺手到分不清哪段是保护 哪段是逃避\n试着写过一些东西 想把那些说不出口的捋清楚\n写到一半 又觉得落到文字上反而更假\n就这么搁着\n像那道墙缝 知道在那儿 就是不想动它\n最难受的不是某件具体的事\n是突然意识到 自己已经很久没有真的在乎过什么\n\n[chorus]\n(Chords: Dmaj7 - Gmaj7 - Em7 - A7)\n(Vocal-Perf: The most powerful and desperate vocal take, with layered harmonies and ad-libs.)\n(Inst: All instrumental elements at full energy. The female vocal pads are prominent.)\n(Mix: The widest and most dynamically compressed part of the track, creating a final emotional climax.)\n(Transition: The beat abruptly cuts out on the final word, leaving only a piano chord to ring out.)\n这不叫释怀\n叫把伤口摁到皮肤下面去\n久了以后表面看起来平\n可按一下 还是会疼\n我想要的从来不是麻木\n我只是还不知道怎么\n在破掉以后 重新学会去感觉\n重新去感觉\n\n[outro]\n(Chords: Dmaj7 - Gmaj7)\n(Vocal-Perf: A final, whispered phrase, breathy and fading.)\n(Inst: Solo piano plays the final two chords with a long, decaying reverb tail.)\n(Mix: Fades completely to silence.)\n等哪天那道缝我修了\n大概就算 好了",
  "cover_prompt": "生成一张无字音乐专辑封面。风格严格参照 20 世纪 Color Field Painting（色域绘画），如 Mark Rothko 晚期作品的色层叠压逻辑与 Helen Frankenthaler 的浸染法（soak-stain technique）。画面的核心色彩与情绪：主体是一大片被压低明度的灰蓝，像混凝土墙面在阴天里的颜色，沉而不透；画面下方约四分之一处渗出一道极窄的暗赭黄，温度隐匿、几乎快消失，像体温的最后一点余迹；两色之间没有清晰边界，只有颜料在粗布上自然洇开形成的模糊地带，传达出一种「感知力被压在很深的地方、尚未彻底熄灭」的内敛张力。\n技法要求：色彩之间的过渡必须模拟颜料在未上浆的粗纹棉布（raw cotton canvas）上自然渗透、晕开的效果，边界柔软但保留颜料浓度不均匀造成的自然深浅变化（pigment pooling）。画面需要呈现真实画布的编织肌理（woven canvas texture），局部可见稀薄处透出的底布纹路。整体色调偏低饱和、微微发灰（muted, desaturated palette），避免荧光感和数字渐变的均匀平滑。\n绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、几何图案、锐利边缘、胶片颗粒滤镜、3D渲染质感。",
