  "prompt": "Genre: Dance-Pop / Contemporary R&B; BPM: 100; Key: C Minor; Rhythm: Driving, syncopated 16th-note groove carried by the bassline and hi-hats; Instruments: Punchy TR-style drum machine (sharp snare, tight kick), dominant sawtooth synth bass playing a melodic riff, arpeggiated synth textures, wide atmospheric pads, subtle lead synth accents; Vocals: Male and Female duet with a male rap feature. Lead male is a high tenor with smooth R&B melismas and extensive falsetto. Lead female has a breathy, processed, almost spoken-word delivery. Rapper uses a high-pitched, ad-lib heavy triplet flow; Mood: Cynical, glamorous, and detached with a dark, propulsive energy; Production: Polished, wide stereo mix with a dominant, punchy low-end and heavily processed, layered vocals with prominent reverb and delay; Structure: Intro, Verse, Pre-Chorus, Chorus, Verse, Bridge, Chorus, Outro; Language: English; Highlight: the relentless, syncopated sawtooth synth bassline that acts as the main hook.",

  "lyrics": "[intro]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Filtered synth pads, sparse atmospheric effects, distant vocal sample.)\n(Vocal-Perf: Breathy, intimate female spoken word, heavily processed with reverb.)\n(Mix: Narrow stereo field, building anticipation.)\nBuilt it all from nothing\nTall glass towers catch the light but never hold the rain\n\n(Transition: Muted kick drum enters, filter sweep on synth pads.)\n[verse]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Full drum machine groove enters with driving synth bass, arpeggiated synth melody.)\n(Vocal-Perf: Smooth male tenor, effortless falsetto transitions, precise rhythmic delivery.)\n(Melody-Rhythm: Vocal phrasing syncopates tightly with the synth bass riff.)\n(Mix: Bass and vocals dominate the center, synths create a wide stereo image.)\nWatch him at the table, cards face down\nSmiling at the cameras like he owns this whole damn town\nBut if you read the fine print (Yeah), it's all smoke\nHe borrowed every penthouse on a handshake and a joke\n\n(Transition: Subtle riser swells into the pre-chorus.)\n[pre-chorus]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Beat continues, pads become more prominent, adding harmonic layers.)\n(Vocal-Perf: Male vocal builds in intensity, using layered harmonies and ad-libs.)\n(Melody-Contour: Ascending melody line, creating tension and anticipation for the chorus.)\n(Mix: Vocals become wider with harmonies and delays.)\nOh, oh-oh-oh-oh, I see through the game (Oh-oh)\nEvery move he makes is just to keep the name (Oh-oh)\nBury all the rivals, bury all the shame (Oh-oh)\nClimb the burning ladder, never feel the flame, ooh-ooh, ooh-ooh\nEvery deal (Every deal) signed in someone's blood\nDiamond cufflinks hiding all that hollow mud\n\n(Transition: Beat drops out for one count, then hits hard with chorus.)\n[chorus]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: All elements at full energy. Bass is punchier, synth layers are brighter.)\n(Vocal-Perf: Layered male vocals, powerful and anthemic delivery.)\n(Hook-DNA: Insistent repetition of a keyword on a simple, ascending rhythmic motif that locks into the main groove, creating a highly memorable earworm.)\n(Melody-Harmonic-Tension: Melody resolves strongly on the root note of each chord, creating a feeling of inevitability and obsession.)\nCrumbling at the top, it's a glass throne\nBleed for every inch of that glass throne\nKill the ones you loved for that glass throne\nCan't trust a single soul on that glass throne\nGlass throne, all alone on the glass throne\nEverybody bows to the glass throne\nYou sold your name to own that glass throne\nNever get out from under the glass throne\n\n(Transition: A short synth fill leads into the next verse.)\n[verse]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Groove remains consistent, but synth layers are slightly more subdued to create space.)\n(Vocal-Perf: Female vocal enters with a breathy, half-sung, half-spoken delivery. Heavy processing and auto-tune create a robotic, detached quality.)\n(Mix: Female vocal is placed front and center, treated with a different reverb space than the male vocal.)\nI watched you rewrite every room you walked into\nPretending that the hunger never showed right through\nAll those careful silences, all the polished lines\nBut nothing ever fills the gap you left behind those eyes\n\n(Transition: Low-pass filter on the beat, creating a brief drop in energy.)\n[bridge]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Bass and a simpler kick/snare pattern. Hi-hats become more trap-influenced with occasional triplets.)\n(Vocal-Perf: Male rap feature with a high-pitched, energetic, ad-lib-heavy flow.)\n(Melody-Rhythm: Rhythmic triplet flow cuts across the straight 16th-note bassline, creating rhythmic friction.)\n(Mix: Vocals are heavily compressed with slapback delay, ad-libs panned wide.)\nEmpire built on sand, still he stands on top of it (Uh-uh)\nCut the hands that helped, now he stands on top of it (Uh-uh)\nWhole world in his grip but he can't stop shaking (Uh-uh)\nGlass throne cracking slow while the city's watching (Uh-uh)\n\n(Transition: Filter sweep riser and drum fill launches back into the full-energy chorus.)\n[chorus]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Maximum energy, additional synth lead layer added for emphasis.)\n(Vocal-Perf: All vocal layers combine - male lead, backing harmonies, and rap ad-libs in the background.)\n(Hook-DNA: Insistent repetition of a keyword on a simple, ascending rhythmic motif that locks into the main groove, creating a highly memorable earworm.)\n(Mix: Widest and loudest point of the song, heavy sidechain compression on synths.)\nCrumbling at the top, it's a glass throne\nBleed for every inch of that glass throne\nKill the ones you loved for that glass throne\nCan't trust a single soul on that glass throne\nGlass throne, all alone on the glass throne (Uh-huh)\nEverybody bows to the glass throne\nYou sold your name to own that glass throne\nNever get out from under the glass throne\n\n(Transition: Beat abruptly cuts, leaving a sustained synth pad.)\n[outro]\n(Chords: Cm - Ab - Eb - Bb)\n(Inst: Synth bass and drums fade out, leaving only the wide atmospheric synth pads and arpeggios.)\n(Sound-Design: A final, heavily reverberated vocal ad-lib echoes and fades into silence.)\n(Mix: Gradual fade out over 8 bars.)",
  "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：深黑色背景上，一把由无数细密白色矢量线条构成的高背椅轮廓，椅身由中心向外逐渐碎裂成尖锐的几何碎片，碎片边缘折射出冷冽的电蓝色与暗金色光线，整体呈现出一种内爆式的向心坍塌感，越靠近中心线条越密集、越锐利。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。",
