  "prompt": "Genre: French House, Dance-Pop, Funk; BPM: 123; Key: C# Major; Rhythm: A driving, syncopated funk groove built around a repetitive, heavily chopped sample. The kick drum is a steady pulse, while a filtered synth bass and the main sample interlock to create a driving pocket syncopation.; Instruments: Punchy drum machine (tight kick, snappy clap), filtered synth bass (rounded, syncopated), chopped funk sample (vocoded texture); Vocals: Male robotic vocal created by heavy vocoder processing. Delivered in a rhythmic, monotone, sung-spoken style. lush background vocal stacks.; Mood: The rhythmic pulsing of a city's neon signs reflected in rain-slicked chrome, a feeling of unstoppable forward momentum at 2 AM.; Highlight: The moment the main vocal phrase is chopped, re-pitched, and transformed into a frantic, melodic synth-like solo, completely recontextualizing the hook.",
  "title": "Keep The Current",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Heavy sidechain compression pumping from the kick onto the bass and sample. Mid-range focused and punchy, with a tight, mono-compatible stereo field.)\n(Inst: Repetitive filtered synth arpeggio, subtle white noise riser.)\n\n[verse]\n(Hook-DNA: Rhythmic mantra with four two-word phrases; Rhythm is a steady eighth-note pattern landing on beats 1 & 2 of each bar; Pitch is a robotic monotone on the root; Repetition is a simple A-B-C-D phrase structure.)\n(Melody-Contour: Flat plateau, zero melodic variation.)\n(Melody-Rhythm: Rhythmic speech, phrases start squarely on beat 1.)\n(Vocal-Perf: Detached, heavily processed male vocoder voice.)\n(Inst: Sparse drum machine beat enters (kick on 1 & 3, clap on 2 & 4), filtered synth bassline enters underneath.)\n(Chords: F#m7 - C#m7 - Dmaj7 - A)\nCharge Up\nBreak Through\nPush On\nFuel The\nRush Now\nBleed Through\nBurn Bright\nAll The Way\n\n[chorus]\n(Hook-DNA: Vocal mantra continues, but the primary hook becomes the instrumental sample; Rhythm is a syncopated 16th-note funk pattern; Pitch anchor is the root and fifth of the underlying chords; Repetition is a constant 4-bar loop.)\n(Melody-Harmonic-Tension: Tension is created rhythmically, not harmonically. The steady on-beat vocal contrasts with the funky, off-beat syncopation of the instrumental sample, creating a powerful groove-based push and pull.)\n(Vocal-Perf: Same robotic delivery, now with more layers and subtle harmonies from the vocoder.)\n(Inst: Full driving drum beat, prominent syncopated synth bass, main chopped funk sample riff, background Rhodes-style electric piano chords.)\n(Mix: All elements pushed forward, sidechain compression becomes an audible rhythmic effect.)\n(Chords: F#m7 - C#m7 - Dmaj7 - A)\nKeep the current, keep it flowing\nVoltage rising, never slowing\nCircuit open, pressure building\nEvery wire in us willing\nKeep the current, keep it flowing\nVoltage rising, never slowing\n\n[bridge]\n(Melody-Harmonic-Tension: A frantic, melodic solo is created by chopping and re-pitching the vocal samples. Tension builds through rapid, often chromatic phrases played over the static four-chord loop, withholding resolution until the final beat before the chorus returns.)\n(Inst: The chopped vocal sample becomes the lead instrument. Drums and bass provide a solid foundation. Low-pass filter sweeps automate over the entire mix, building and releasing energy.)\n(Sound-Design: Aggressive band-pass and low-pass filter sweeps creating dramatic tension and release.)\n(Chords: F#m7 - C#m7 - Dmaj7 - A)\nConducted by the pulse inside our chest\nNo insulation left to second-guess\nThe grid demands the voltage we possess\nSo let it arc — let nothing disconnect\n\n[chorus]\n(Hook-DNA: Vocal mantra continues, but the primary hook becomes the instrumental sample; Rhythm is a syncopated 16th-note funk pattern; Pitch anchor is the root and fifth of the underlying chords; Repetition is a constant 4-bar loop.)\n(Melody-Harmonic-Tension: Tension is created rhythmically, not harmonically. The steady on-beat vocal contrasts with the funky, off-beat syncopation of the instrumental sample, creating a powerful groove-based push and pull.)\n(Vocal-Perf: Same robotic delivery, now with more layers and subtle harmonies from the vocoder.)\n(Inst: Full driving drum beat, prominent syncopated synth bass, main chopped funk sample riff, background Rhodes-style electric piano chords.)\n(Mix: Maximum energy, heavy compression and pumping.)\n(Chords: F#m7 - C#m7 - Dmaj7 - A)\nKeep the current, keep it flowing\nVoltage rising, never slowing\nCircuit open, pressure building\nEvery wire in us willing\nKeep the current, keep it flowing\nVoltage rising, never slowing\n\n[outro]\n(Vocal-Perf: Vocal phrases become fragmented, stuttered, and chopped.)\n(Inst: Elements are stripped away one by one. The drum machine deconstructs, leaving just a filtered kick.)\n(Sound-Design: A long low-pass filter sweep closes over the entire track, with delay trails on the final vocal fragments.)",
  "cover_prompt": "生成一张无字音乐专辑封面。风格参照 1960s Op Art（欧普艺术）代表 Bridget Riley 与 Victor Vasarely 的视觉振动效果，叠加 Risograph（孔版印刷）的手工印刷质感。画面核心：高压电弧在极度克制的平面几何构成中迸发——以密集的平行曲线群从画面左下角向右上角扇形辐射，线条密度从边缘向中心急剧压缩，制造强烈的视觉加速感与摩尔纹振动效果；配色锁定在深海蓝（navy）与高压黄（electric yellow）两个专色，叠印区域呈现第三色黄绿（chartreuse），模拟孔版油墨在纸面的真实叠色行为；边缘有极细微的套色偏移与锯齿感，纸面带有可见的微粒质感。技法要求：图形必须是纯平面的几何构成，通过线条的密度渐变和高对比色彩的并置制造摩尔纹（moiré pattern）式的视觉振动感。关键——必须模拟 Risograph 孔版印刷的特征：颜色叠印处出现第三色（overprint color mixing），墨层分布轻微不均匀（ink density variation），边缘有极细微的锯齿和套色偏移（slight misregistration），纸面带有微粒质感而非绝对光滑。色彩限定在 2-4 个专色（spot colors）以内，饱和度高但不发荧光，如同真实油墨色而非屏幕色。绝对禁止：任何文字/字母/拼音、人物或人物轮廓、具象物体、自然风光、写实肌理、水彩效果、3D渲染或光影透视。",
