  "title": "绿灯没动",
  "lyrics": "[intro]\n(Mix: High-fidelity, wide stereo image. Bass/kick centered. Drums have natural room reverb. Guitars/synths panned L/R. Clean, lush reverb on guitars and synth pads. Smooth, transparent master bus compression.)\n(Inst: Simple drum machine pattern, then full acoustic kit enters with a solid backbeat. Clean electric guitar plays a distinctive, constant arpeggiated motif. Warm synth pads swell underneath.)\n(Hook-DNA: Rhythmic: dotted-eighth-sixteenth arpeggio pattern on guitar, accenting beats 1 and 3. Pitch: circles around the 3rd and 5th of the tonic chord. Repetition: motif repeats over chord changes, creating a constant melodic layer.)\n\n[verse]\n(Transition: A simple one-bar drum fill and bass slide lead into the verse.)\n(Vocal-Perf: Female lead, soft chest voice, breathy and intimate, mezzo-piano.)\n(Inst: Rhythm section locks into a simple, driving groove. The clean guitar arpeggio continues as the main melodic element. Bass follows root notes, very grounded.)\n(Melody-Contour: Narrow range, mostly stepwise motion; phrases start on upbeat, land on downbeat.)\n(Chords: E - A - E - A - C#m - B - A - B)\n广播说今晚有阵雨\n你把音量调低了一格\n前排卡车刹了又停\n我们堵在第三条道里\n红灯倒计时剩十二\n你说这个数字像什么\n\n[pre-chorus]\n(Transition: A soft cymbal swell and increase in synth pad volume lift the energy.)\n(Vocal-Perf: Male lead enters, clear and forward in the mix, contrasting the female's softer tone.)\n(Inst: Drums build slightly with more frequent cymbal hits. Bassline becomes more melodic, leading into the chorus.)\n(Melody-Contour: Ascending line builds tension; longer held notes; lands on the dominant to set up the chorus.)\n(Chords: F#m - G#m - A - B)\n像一个不想结束的句子\n我们没有要去的目的地\n绿灯亮了也不必急\n你手放在档位上没挪移\n\n[chorus]\n(Transition: The full band crashes in on the downbeat, a sudden explosion of sound.)\n(Mix: Stereo image widens significantly; perceived loudness increases. Distorted guitars dominate the sides.)\n(Vocal-Perf: Female and Male duet in harmony, full-voiced and powerful, mezzo-forte.)\n(Inst: Heavy, distorted rhythm guitars enter with power chords, driving the energy. Drums are louder, with more crash cymbals.)\n(Melody-Contour: Higher register than verse, wider melodic leaps; phrases form an arch, peaking mid-phrase.)\n(Chords: E - A - C#m - B)\n(Hook-Recall: The clean arpeggio motif from the intro is layered underneath the distorted guitars, maintaining the core hook.)\n(Melody-Harmonic-Tension: Melody emphasizes the major 7th over the tonic chord before resolving down, creating sweet tension; holds the 2nd over the V chord at the end of key phrases, delaying resolution.)\n整个宇宙在往前开\n我们停在原地多自在\n整个宇宙在往前开\n绿灯亮了我们没动\n动了才怪\n\n[interlude]\n(Transition: Chorus vocals end, leaving a long reverb tail over which the solo guitar swells.)\n(Inst: Melodic lead guitar solo with a slightly overdriven, singing tone. The full rhythm section provides a powerful backing. Synth pads are more prominent.)\n(Melody-Contour: (Instrumental) Lead guitar traces a phrase that climbs in steps then hangs on a single bent note, like a question left unanswered mid-air.)\n(Chords: E - A - C#m - B - F#m - G#m - A - B)\n\n[bridge]\n(Transition: The final chord of the interlude rings out, and the instrumentation drops back dramatically.)\n(Vocal-Perf: Duet vocals become softer and more reflective, dropping in dynamics.)\n(Inst: Texture thins out to clean guitars, bass, and a simpler drum beat. Distorted guitars are absent.)\n(Melody-Contour: Lower range, more conversational and rhythmic; based on repetitive melodic fragments.)\n(Chords: A - E - B - C#m - A - E - B - B)\n(Melody-Harmonic-Tension: Phrases end on the 5th over the V chord, creating a feeling of suspension and questioning that sets up the final emotional peak.)\n外面的城市大得很\n路牌指向十几个方向\n我们困在这一格车厢\n哪里都不去\n哪里都到了\n\n[chorus]\n(Transition: A powerful, rolling drum fill launches the song back into the high-energy chorus.)\n(Mix: The widest and fullest mix of the song, with additional vocal ad-libs and lead guitar fills panned to the sides.)\n(Vocal-Perf: Highest energy duet performance, with emphatic delivery and layered harmonies.)\n(Inst: Full band at maximum intensity. Lead guitar adds counter-melodies and fills between vocal phrases.)\n(Melody-Contour: Same core contour as the first chorus, but delivered with more force and slight rhythmic variations.)\n(Chords: E - A - C#m - B)\n(Hook-Recall: Arpeggio motif weaves in and out with the new lead guitar fills, creating a dense melodic texture.)\n(Melody-Harmonic-Tension: The established tension points are hit with more intensity, making the eventual resolution feel more climactic.)\n这个房间四扇玻璃窗\n你呼出的气把它变白了\n这个房间四扇玻璃窗\n绿灯亮了我们没动\n就这样好\n\n[outro]\n(Transition: The final chorus chord hangs, then all instruments cut out except for a single guitar and pad.)\n(Vocal-Perf: The final line is delivered softly and intimately, a stark contrast to the previous chorus.)\n(Inst: All instruments fade out, leaving the clean guitar arpeggio and a warm synth pad to resolve on the tonic chord.)\n(Melody-Contour: The final vocal phrase descends gently to the tonic, providing a sense of closure.)\n(Chords: E)\n你的手边\n就是我要去的地方",
  "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：黄昏时分车窗玻璃的暖琥珀色与雾气白之间的温柔渗透，底层透出一片沉静的灰蓝，中间层是被呼出的热气晕开的淡奶白，最表层是将散未散的橘黄暖光，三层色彩形成一种「困在某个时刻、不想离开」的悬停感。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。",
