  "prompt": "Genre: Jazzy Hip-Hop / R&B; BPM: 96; Key: A major; Rhythm: Relaxed, swung hip-hop groove.

  "title": "候机厅",
  "lyrics": "[intro]\n(Chords: Dmaj7 - C#m7 - Bm7 - E9)\n(Inst: Mellow Rhodes piano chords, clean single-note guitar melody, subtle water bubble SFX.)\n(Mix: Intimate, centered soundscape.)\n(Hook-DNA: The core jazzy chord progression is established.)\n\n[verse]\n(Chords: Dmaj7 - C#m7 - Bm7 - E9)\n(Vocal-Perf: Male, conversational Mandarin rap, smooth and relaxed delivery, close-mic'd.)\n(Inst: A laid-back hip-hop beat enters with a soft cross-stick snare. A round, melodic electric bass locks in with the kick. Rhodes and guitar provide harmonic support.)\n(Energy: Chill, narrative, spacious.)\n(Transition: All instruments except Rhodes drop out for the final beat, creating a moment of suspension.)\n凌晨两点的航站楼，暖气管嗡嗡作响\n旅行箱搁在脚边，你睡着了，睫毛静止\n我没什么要去的地方\n只是不想太早道别这件事，你懂的吗\n候机厅的椅子硬得很\n但你头靠着我肩，我没动过一寸\n广播念着陌生的城市名\n像是某种只有我们能解的密语\n你的手机屏幕暗了又亮\n来电是你该去赴的航班，不是我\n我把耳机线绕了三圈\n把这一段安静捂得热\n外头远机坪有架飞机滑过跑道\n灯光一闪就消失在云层折叠处\n你醒来问我现在几点\n我说还早，你又闭上眼\n\n[chorus]\n(Chords: Dmaj7 - C#m7 - Bm7 - E9)\n(Vocal-Perf: Female, airy and breathy Japanese R&B vocal. Soft, layered harmonies add a shimmering texture.)\n(Inst: Full groove returns. The guitar becomes more active with melodic fills and chordal stabs.)\n(Mix: The stereo field widens. Vocals have a touch more reverb, blending into the track.)\n(Energy: A gentle lift, blossoming and romantic.)\nそっと 肩に寄りかかって\nまだ 時間は止まってる\n行かないで 夜明けが来るまで\nここだけの やさしい嘘でいい\n\n[verse]\n(Chords: Dmaj7 - C#m7 - Bm7 - E9)\n(Vocal-Perf: Male rap resumes, maintaining the consistent cool and conversational flow.)\n(Inst: The instrumental groove remains steady. The guitar offers subtle variations in its fills, responding to the vocal.)\n(Energy: Returns to the chill, narrative vibe of the first verse.)\n我们认识的方式很随机\n共同好友转发的那条动态，你点了心\n后来我们聊到快天亮\n说着有朝一日要去的某个城市，说着说着\n变成了今晚这张登机牌\n我问你要不要我送，你说不用\n结果你又发了一条"你在哪"\n我在候机厅咖啡机旁边等你\n自动贩卖机的灯管有一格坏掉\n字迹残缺，倒映在你拖行李箱的眼镜片上\n比起道别，我更不习惯的\n是那种"下次"的感觉，虚的，飘的\n登机口离这儿走路要七分钟\n我已经在心里计算过三遍了\n到底是把话说完再走\n还是留着，等某次起飞之后\n\n[chorus]\n(Chords: Dmaj7 - C#m7 - Bm7 - E9)\n(Vocal-Perf: Female vocal, performance feels slightly more confident, with subtle ad-libs appearing in the background.)\n(Inst: All elements are present. The Rhodes plays with slightly more rhythmic complexity.)\n(Mix: Maintains the full, wide sound of the first chorus.)\n(Energy: Reaches the same gentle peak, feels conclusive.)\nそっと 肩に寄りかかって\nまだ 時間は止まってる\n行かないで 夜明けが来るまで\nここだけの やさしい嘘でいい\n\n[bridge]\n(Chords: F#m7 - Bm7 - Emaj7 - A7)\n(Vocal-Perf: Female vocal melody becomes more flowing and lyrical, distinct from the chorus melody.)\n(Inst: The chord progression shifts, creating a sense of forward motion and emotional lift. The beat remains consistent.)\n(Energy: A gentle build in tension, setting up the return of the main theme.)\n(Transition: A subtle cymbal swell leads back into the final chorus.)\n搭乗口の声\n遠くなっていく\nまだここに いたい\nあなたの 隣で\n\n[outro]\n(Chords: Dmaj7 - C#m7 - Bm7 - E9)\n(Vocal-Perf: Female vocal repeats the main chorus hook with a feeling of finality.)\n(Inst: The full band plays through the progression once more before beginning a gradual fade.)\n(Sound-Design: As the instruments fade, the water bubble SFX returns, bringing the song to a gentle close.)\nそっと 肩に寄りかかって\nまだ 時間は止まってる\n行かないで 夜明けが来るまで",
  "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：深夜候机厅的温沉感——以暖灰米色与烟褐色为主色调，上层叠压一层若隐若现的冷蓝渗透带，象征即将来临却被刻意忽视的黎明；底部沉淀着微量琥珀暖色，如同长夜末尾残存的一点体温。整体色彩关系是：暖灰主调中，冷与暖悄悄对峙，无人开口。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。",
