  "prompt": "Genre: Mandopop / Pop Ballad; BPM: 166; Key: F# Major; Rhythm: Slow, emotional half-time pop groove at 83 BPM feel. Kick on 1 & 3, clean snare on the backbeat. Ticking 16th-note hi-hats provide subtle drive, creating a floating, expansive feel.; Instruments: Arpeggiated grand piano, warm acoustic guitar textures, atmospheric clean electric guitar swells with delay, round supportive electric bass, modern pop drum kit; Vocals: Female; Clear, breathy, and emotive mid-to-high range voice with a delicate head-voice. Gentle, conversational verses build to a powerful, sustained chorus. Processed cleanly with subtle reverb for a polished, intimate sound.; Mood: Watching the last train pull away from the platform on a cold, damp evening, the station lights blurring through unshed tears.; Highlight: The downbeat of the first chorus (0:58) where the full band and soaring strings enter suddenly under the lifted vocal melody, creating an expansive, heart-wrenching emotional release.",

  "lyrics": "[intro]\n(Chords: F# - C#/F - D#m - B)\n(Inst: Ethereal synth pads, clean piano melody playing the main motif.)\n(Mix: Wide and spacious, setting a reflective tone.)\n\n[verse]\n(Chords: F# - C#/F - D#m - B)\n(Inst: Piano continues, subtle acoustic guitar arpeggios enter. Clean bass guitar enters halfway through with simple root notes.)\n(Vocal-Perf: Gentle, breathy, conversational tone, mezzo-piano dynamic.)\n(Mix: Vocals are intimate and centered.)\n(Transition: Light cymbal swell builds anticipation.)\n你走前的那个周二下午\n洗碗机还没跑完它最后一轮\n我站在厨房 听转速放慢\n忘了说 哪怕一个字\n茶几上你摁灭的那截烟\n灰还在 人已经不见\n\n[chorus]\n(Chords: B - F#/A# - G#m - C#)\n(Inst: Full pop drum kit enters with a steady half-time groove. Soaring string section provides a lush, emotional backdrop. Bass is solid and foundational.)\n(Vocal-Perf: Stronger, more sustained chest voice, mezzo-forte, conveying a sense of longing.)\n(Mix: Expands into a wide stereo image, strings fill the space, drums punch through the center.)\n(Transition: The final chord hangs with reverb before a clean cut into the next section.)\n那张便利贴还贴在门框\n三个字的笔迹 越来越模糊\n我每天出门都低头经过它\n假装没看见 其实全都记住\n胶快失效了 纸角翘起来\n像我 还差一点点 才能放下\n\n[verse]\n(Chords: F# - C#/F - D#m - B)\n(Inst: Drums simplify to a kick and hi-hat pattern. Strings pull back to soft, sustained pads. Piano remains the core element.)\n(Vocal-Perf: Returns to a softer, more reflective delivery, but with more forward momentum than the first verse.)\n(Mix: Narrows slightly to refocus on the vocal intimacy.)\n换季收拾衣柜翻出你的帽子\n压在最底下 绒毛还没散\n我坐在地板上发了很久的呆\n最后装进袋子 放回原处\n\n[bridge]\n(Chords: G#m - D#m - E - C#)\n(Inst: Arrangement strips back to piano, atmospheric guitar swells, and bass. Strings hold a single, tense high note.)\n(Vocal-Perf: Builds in intensity from a near-whisper to a powerful plea, leading directly into the final chorus.)\n(Melody-Contour: Ascending line creating tension and release.)\n(Transition: A powerful drum fill and cymbal crash launches into the final chorus.)\n我试过把那张便利贴撕掉\n手指捏住角 又慢慢松开\n门框那块浅色的印\n贴着贴着 成了我留你的方式\n\n[chorus]\n(Chords: B - F#/A# - G#m - C#)\n(Inst: The most powerful section. All instruments playing at full intensity. String section plays an soaring counter-melody. Cymbals crash on downbeats.)\n(Vocal-Perf: Peak emotional delivery, powerful and sustained, with subtle ad-libs and harmonies layered.)\n(Mix: Maximum width and depth, a true cinematic climax.)\n那张便利贴还贴在门框\n三个字的笔迹 越来越模糊\n我每天出门都低头经过它\n假装没看见 其实全都记住\n胶快失效了 纸角翘起来\n像我 还差一点点 才能放下\n\n[outro]\n(Chords: B - F# - G#m - F#)\n(Inst: Deconstructs the arrangement, fading out with the main piano motif and the lingering tail of the string section.)\n(Mix: Slowly fades to silence, leaving just the piano reverb.)\n(Structure: Instrumental fade out.)",
  "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：一张微微翘起边角、泛黄的小方形纸片孤悬于画面中央偏上，四周被大量留白包围，纸片底部投下一道极细的柔和阴影，背景是从暖米白向冷灰蓝过渡的水彩渐变，质地如同旧信封的纸面。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。",
