  "title": "掰开它",
  "lyrics": "[intro]\n(Hook-DNA: Syncopated palm-muted eighth-note riff, accents on downbeats and '&' of 2; circles around the root (Fm), emphasizes flat 7th for tension; main 2-bar riff repeats, with a fill on the 4th repetition)\n(Inst: Heavily distorted electric guitar playing a syncopated hard rock riff. Filtered electronic drums enter.)\n(Mix: Wide stereo image. Punchy, compressed drums centered. Heavy guitars panned hard left/right. Vocals are dry, centered, and upfront. Deep sub-bass anchored in the mono center. A touch of plate reverb for space.)\n(Chords: Fm - E♭ - D♭ - C7)\n\n(Transition: Guitar riff drops to a lower gain, full drum kit enters with 808 bass.)\n[verse]\n(Melody-Contour: Narrow range, on-the-beat speech-rhythm; phrases build intensity with faster subdivisions.)\n(Vocal-Perf: Aggressive, confident delivery; steady mezzo-forte; clipped, precise diction.)\n(Inst: Palm-muted guitar riff continues under vocals. Punchy trap beat with fast hi-hats.)\n(Mix: Vocals sit on top of the instrumental, very clear.)\n(Chords: Fm - E♭ - D♭ - C7)\n比赛完了哨声响了我没走\n站在更衣室门口盯着那扇厚门\n我说不要 其实脚底生了根\n积水漫过鞋帮我也没有动身\n汗还没干 胸口还压着一块石\n刚才那一局让我牙关咬得死\n我说够了 其实耳朵在捕捉\n里面有没有你换鞋的那点声息\n走廊灯管嗡嗡地抖 照着我的影子\n我把手揣进口袋又捏成拳的样子\n我说走开 其实背脊贴着墙\n等你推开那道门的那一个瞬间\n\n(Transition: Guitar drops out, leaving bass and drums; riser synth swells.)\n[pre-chorus]\n(Melody-Contour: Rhythmic pattern simplifies, builds tension by holding on end-of-phrase words.)\n(Vocal-Perf: Delivery becomes more menacing, slightly lower in pitch.)\n(Inst: Stripped back to drums and 808 bass. A filtered atmospheric pad adds tension.)\n(Chords: Fm)\n我以为我是来讨说法\n站直了 绷紧了 不服输的姿态\n可这条走廊每走一步都像往回爬\n越往前 越清楚 我在等的是什么啊\n\n(Transition: Full band slams back in on the downbeat after a half-beat of silence.)\n[chorus]\n(Hook-Recall: The main distorted guitar riff from the intro returns at full force, defining the chorus.)\n(Melody-Contour: More melodic, sung-rap style in Cantonese; phrases have a clear ascending/descending arc.)\n(Melody-Harmonic-Tension: Vocal melody emphasizes the 3rd and 5th, creating a strong consonant feel over the power chords, releasing tension built in the pre-chorus.)\n(Vocal-Perf: Sung-rap delivery; powerful and anthemic; layered vocals for width.)\n(Inst: Main guitar riff at maximum distortion. Drums are heavy, with cymbal crashes for emphasis.)\n(Mix: Stereo field widens significantly. Vocals layered with harmonies and subtle delay.)\n(Chords: Fm - G♭ - A♭ - B♭m)\n拳头握紧等你来掰\n握紧 是因为怕你不来\n这一场仗我早就想败\n只是没人看穿 没人拆开\n拳头握紧等你来掰\n\n(Transition: Beat and bass continue, guitar switches to a slightly different, less intense riff.)\n[verse]\n(Melody-Contour: Varied flow with complex rhythmic patterns and changing subdivisions; conversational then aggressive.)\n(Vocal-Perf: Dynamic shifts from conversational to shouting; extensive ad-libs.)\n(Inst: Groove remains consistent. Occasional guitar stabs and synth FX punctuate the flow.)\n(Chords: Fm - E♭ - D♭ - C7)\n你出来的时候头发还是湿的\n毛巾搭着肩 眼睛往地上看\n我站在那里像棵生锈的铁\n张嘴想喊凭什么 声音卡在喉管间\n对视三秒 我没先移开视线\n但脚趾头已经在鞋里面弯\n我以为对抗是两个人的战场\n后来才发现 战场只在我这边\n我跟自己磨了一整个下半场\n想认输的念头比你打我还疼\n我把它压下去 又弹起来更强\n它不是软弱 它叫做 我还在乎你这桩\n\n(Transition: Vocal ad-lib builds into the chorus drop, full band re-enters.)\n[chorus]\n(Hook-Recall: The main distorted guitar riff returns, now with added lead guitar fills.)\n(Melody-Contour: Sung-rap style in Cantonese; phrases have a clear ascending/descending arc, more intense than first chorus.)\n(Melody-Harmonic-Tension: Vocal melody emphasizes the 3rd and 5th, creating a strong consonant feel over the power chords, releasing tension.)\n(Vocal-Perf: More aggressive delivery than first chorus; ad-libs fill spaces between lines.)\n(Inst: Full instrumentation with added counter-melody from a wailing lead guitar.)\n(Mix: Even wider and louder. Lead guitar fills are panned to the sides.)\n(Chords: Fm - G♭ - A♭ - B♭m)\n拳头握紧等你来掰\n握紧 是因为怕你不来\n这一场仗我早就想败\n只是没人看穿 没人拆开\n拳头握紧等你来掰\n\n[bridge]\n(Melody-Contour: Spoken-word then explodes; rhythmic tension peaks before final chorus.)\n(Vocal-Perf: Raw, stripped-back vocal delivery; no doubling; maximum emotional exposure.)\n(Inst: Guitar drops to single-note picking. Kick drum only. Then full band erupts on final line.)\n(Mix: Vocal pushed forward, everything else recedes. Massive reverb tail on final line.)\n(Chords: Fm - D♭ - A♭ - C7)\n我不是在等你道歉\n我不是在证明我更硬\n我只是站在这条走廊里\n没办法假装那局输得心安\n你以为我握紧了是要出击\n其实我只是怕一松手就散\n我把拳头握到最紧\n只是为了让你来掰开它\n\n(Transition: The final vocal line echoes out, music continues.)\n[outro]\n(Inst: The main guitar riff repeats and breaks down, with improvisational lead guitar licks over the top. Beat deconstructs until only the guitar riff remains, then fades.)\n(Mix: Automation fade on master track. Reverb tails become more prominent as instruments fade.)\n(Chords: Fm)",
  "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：大量密集的水平线条从画面中央向两侧逐渐扭曲弯折，形成一个隐约的向内收紧再骤然释放的张力场，仿佛有什么力量从内部把线条挤压成拳形后又被外力掰开的瞬间；整体色调以深铁灰与哑光暗红为主色，叠印区域出现锈橙色，边缘带有套色偏移与油墨颗粒感，背景是粗纹纸张的微粒质感，整体克制、紧绷、蓄而未发。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。",
