  "prompt": "Genre: Cantopop, Eurodance, Trance; BPM: 128; Key: G# minor; Rhythm: Driving 4/4 Eurodance beat with a prominent kick on each beat, clap/snare on 2 and 4, and energetic 16th-note synth arpeggios. Off-beat synth bassline.; Instruments: TR-909 style drum machine (punchy kick, sharp clap), driving off-beat synth bass. Layered synthesizers: bright, detuned supersaw lead for hooks, plucky arpeggiated synths for rhythm; Vocals: Male tenor, clear and direct pop delivery in Cantonese. Processed with heavy reverb and delay to blend into the dense mix. Some sections feature a lower, spoken English rap.; Mood: Euphoric, high-energy, nostalgic, driving club anthem.; Production: Loud, compressed mix typical of early 2000s dance music. Wide stereo image from synth layers and effects. Vocals sit within the mix, not on top. Heavy use of reverb and delay to create a large, energetic space.; Highlight: The euphoric and memorable supersaw synth lead melody.",

  "cover_prompt": "生成一张现代平面设计（Modern graphic design）风格的几何艺术图片作为无字音乐专辑封面。画面的核心是：纯黑背景中，数十条细密的弧线从画面四角向中心螺旋收拢，形成一个巨大的涡旋结构，涡旋核心迸发出高饱和度的电蓝与品红渐变光，越往外层颜色越冷、越暗，最终在边缘消融成深空紫黑；整体仿佛一个星系正在向内坍缩，又像一次无法停止的自由落体。采用纯粹的数字矢量图形（Vector art）媒介，质感极致平滑干净（Smooth and clean textures），绝对没有任何画笔笔触、水彩晕染或写实肌理。通过线条的排列、交错和高对比度色彩，创造出类似欧普艺术（Op Art）的视觉错觉，赋予画面极强的视觉动感（Sense of movement）和空间纵深感（Depth）。强烈要求：这是一张纯数字生成的抽象几何图形作品，绝对不要出现任何具象的自然风光、人物、动物或实体物品！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！传达出精准、充满秩序感且极具律动（Groove）的现代视觉效果。",
