  "title": "还欠着",
  "lyrics": "[intro]\n(Chords: C#m - A - E - B)\n(Inst: Lyrical cello melody playing a melancholic theme over a sparse, arpeggiated grand piano.)\n(Mix: Intimate and spacious, setting a reflective tone with heavy room reverb on the cello.)\n\n[verse]\n(Chords: C#m - G#m - A - E - F#m - C#m - A - B)\n(Vocal-Perf: Conversational, breathy, mezzo-piano, gentle phrasing, narrative focus.)\n(Inst: Vocals and piano dominate. A simple, clean bass line enters, providing a subtle pulse. Acoustic guitar strums lightly in the background.)\n(Melody-Rhythm: Flowing and speech-like, following the lyrical cadence.)\n那盆植物你走前没带走\n浇水的频率我猜了很久\n太勤它烂根太懒它发黄\n我查了好多遍才养到现在这样\n其实我也知道你不是忘了它\n只是留了个借口方便回来看\n\n(Transition: Piano chords build slightly in volume, a single cymbal swell leads into the chorus.)\n[chorus]\n(Chords: E - B/D# - C#m - G#m - A - E - F#m - B)\n(Vocal-Perf: Dynamic lift to mezzo-forte, powerful and emotionally resonant chest voice, controlled belting on the hook.)\n(Inst: Full band enters. A solid, half-time drum beat with a crisp snare on beat 3. Cello plays long, supportive notes. Piano shifts to strong block chords.)\n(Melody-Contour: The melody ascends dramatically on the opening line, creating the song's signature emotional peak.)\n我还欠你一顿没吃完的饭\n筷子搁下去就开始吵那晚\n我还欠你一句没出口的软话\n憋在喉咙里硬撑到天亮散\n我还欠你一个转过身的机会\n那时候脚步太快没给你拦\n这些账我替你记着一笔一笔\n不知道还给谁才算\n\n(Transition: The final chord of the chorus rings out, and the energy immediately drops for the bridge.)\n[bridge]\n(Chords: A - B - G#m - C#m - F#m - G#m - A - B)\n(Vocal-Perf: Intensity builds again from introspection to desperation. The delivery becomes more urgent.)\n(Inst: A clean electric guitar plays arpeggiated fills. Drums become slightly more complex with subtle hi-hat patterns. The harmony creates tension.)\n(Mix: The stereo field widens as more instrumental layers are introduced.)\n那盆植物上个月抽了新芽\n我蹲在地上盯了好半天\n它长得那么用力那么理直气壮\n我鼻子发酸\n你欠我的那些我早就不计较\n可我欠你的那些压在肋骨间\n越长越重\n没处还\n\n(Transition: A powerful drum fill and a sustained vocal note launch into the final chorus.)\n[chorus]\n(Chords: E - B/D# - C#m - G#m - A - E - F#m - B)\n(Vocal-Perf: Full forte, peak emotional delivery, slight vocal fry and strain for authenticity. Ad-libbed harmonies may appear.)\n(Inst: All instruments at maximum energy. Distorted electric guitar enters, playing long, soaring notes. Crash cymbals accent the downbeats.)\n(Mix: The mix is dense and powerful, creating a climactic wall of sound. Vocals are right at the front, driving the emotion.)\n我还欠你一顿没吃完的饭\n筷子搁下去就开始吵那晚\n我还欠你一句没出口的软话\n憋在喉咙里硬撑到天亮散\n我还欠你一个没说完的名字\n叫到一半就被风吹断\n这些账压着我睡不着也忘不掉\n是你留给我最重的牵绊\n\n[outro]\n(Chords: A - Am - E)\n(Vocal-Perf: Returns to a soft, breathy whisper. Delivery is resigned and sorrowful.)\n(Inst: The full band cuts out, leaving only a sparse piano playing the final chords. A final, lingering cello note fades out.)\n(Structure: Decelerando and fade to silence.)\n那盆植物\n还活着\n我还在\n还欠着",
  "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：深绿灰色从画面底部缓慢向上渗透，中段被一层混浊的暖白阻断，像某种生长被压住又没有完全停下来——不是悲伤的颜色，是那种还没有结论、事情仍在进行中的沉默。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。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。",
