  "prompt": "Genre: Mandopop / Dream Pop / Indie Rock; BPM: 99; Key: E Major; Rhythm: Driving indie-rock backbeat with 8th-note hi-hats; tight, on-the-grid feel; bass on downbeats.; Instruments: Punchy acoustic drums; clean DI bass; arpeggiated rhythm guitar (chorus fx); overdriven lead guitar fills; warm synth pads; plucky synth lead.; Vocals: Female and Male duet; female lead is bright and airy in a mid-high range; male provides softer, lower harmony; processed with clean reverb.; Melody: Verse: stepwise conversational; Chorus: soaring melodic arch landing on tonic; syncopated.; Mood: Driving fast on a coastal highway at dusk, windows down, heading towards an unknown, exciting city.; Production: High-fidelity, radio-ready polish; wide stereo image with panned guitars; clean reverb and delay for depth.; Language: Mandarin; Highlight: The harmonic shift in the bridge, where the duet vocals float over a sustained chord, creating a brief sense of weightlessness before the final chorus.",
  "title": "One More Exit",
  "lyrics": "[intro]\n(Hook-DNA: Rhythm: syncopated 16th-note pattern emphasizing upbeats; Pitch: circles around 3rd and 5th scale degrees, resolves to root on beat 1 of final bar; Repetition: pattern repeats 4 times with subtle filter modulation.)\n(Inst: Plucky synth lead, clean electric guitar arpeggio, punchy drums, clean DI bass.)\n(Mix: Wide stereo field; drums and bass centered, synth arp panned left, clean guitar panned right; transparent bus compression; medium hall reverb on all elements for depth.)\n(Chords: E - A - C#m - B)\n\n[verse]\n(Transition: Synth arp fades slightly, female vocal enters center.)\n(Melody-Contour: Narrow range, stepwise motion; phrases land on 3rd or 5th; conversational, on-the-beat rhythm.)\n(Vocal-Perf: Female lead: soft, airy chest voice, mezzo-piano. Male harmony enters in second half: breathy, understated.)\n(Inst: Rhythm section continues, warm synth pad enters subtly, providing harmonic foundation.)\n(Mix: Vocals brought forward, centered.)\n(Chords: E - A - E - A | C#m - A - B - B)\nThe last sign said eleven miles to go\nYou turned the radio up, kept it low\nThe dashboard glowed a shade of amber light\nYour elbow out the window, touching night\nI watched the exit numbers counting down\nAnd something in my chest began to drown\nTen miles of painted lines still left to burn\nI eased up on the gas before the turn\n\n[chorus]\n(Transition: Drum fill with cymbal swells, bass becomes more active, building energy.)\n(Hook-Recall: Main synth arpeggio from intro returns, reinforcing the core melodic hook.)\n(Melody-Harmonic-Tension: Melody lands on the major 7th over the IV chord (A) in first half of phrase, creating bright tension before resolving down to the 5th.)\n(Melody-Contour: Soaring arch, peaks on downbeat of bar 3; phrases land on tonic; syncopated and energetic.)\n(Vocal-Perf: Both vocals: full voice, mezzo-forte, open timbre, more pronounced vibrato.)\n(Inst: Full band energy. Overdriven guitar adds melodic fills between vocal phrases.)\n(Mix: Stereo field widens, guitars pushed slightly further out.)\n(Chords: A - E - B - C#m | A - E - B - E)\nThis whole highway is ours tonight\nEvery curve, every bending white line\nThis whole highway is ours to keep\nLong as we're rolling, I'm yours to reach\nDon't let the road run out on me\n\n[interlude]\n(Transition: Chorus ends with sustained vocal note and cymbal crash, leading directly into guitar melody.)\n(Melody-Contour: (Lead Guitar) Ascending line with expressive bends, peaks mid-solo; uses major pentatonic phrases; rhythmically free over the groove.)\n(Inst: Overdriven guitar takes the lead melody. Rhythm section maintains chorus energy. Synth pads swell underneath.)\n(Mix: Lead guitar centered with dedicated delay and reverb, pushing other elements slightly back.)\n(Chords: A - E - B - C#m | A - E - B - E)\n\n[bridge]\n(Transition: Energy drops suddenly from interlude, rhythm becomes half-time feel, sustained synth pad becomes prominent.)\n(Melody-Harmonic-Tension: Vocal phrases hang unresolved on the 2nd degree over the V chord (B), creating sustained anticipation, delaying resolution until the final bar.)\n(Melody-Contour: Floating, legato phrases; narrow range; rhythmically sparse, emphasizing space between lines.)\n(Vocal-Perf: Duet becomes soft and intimate again, close-mic'd, breathy delivery.)\n(Inst: Stripped back to bass, soft drums (rim clicks/light snare), and prominent synth pads. Clean guitar arpeggios re-enter.)\n(Mix: Mix narrows, focus shifts to vocals and atmospheric pads.)\n(Chords: G#m - A - E - B)\nI could see the city lights begin to bloom\nYour hand still resting warm against my arm\nSo I let go of the gas\nI let go to hold on\nI took one more exit just to keep you close\nScared that if we arrive, this ends\n\n[chorus]\n(Transition: Drum fill and cymbal swell launch the band back into full energy from the sparse bridge.)\n(Hook-Recall: Synth arpeggio and driving rhythm section return at maximum intensity.)\n(Melody-Harmonic-Tension: Melody again creates tension by landing on the major 7th over the IV chord, but with more aggressive vocal delivery and added high harmony.)\n(Melody-Contour: Soaring arch, peaks on downbeat of bar 3; phrases land on tonic; syncopated and energetic.)\n(Vocal-Perf: Duet at peak intensity, forte, slight vocal grit on higher notes for emotional emphasis.)\n(Inst: Full band at maximum energy, crash cymbals on downbeats.)\n(Chords: A - E - B - C#m | A - E - B - E)\nThis whole highway is ours tonight\nEvery curve, every bending white line\nThis one window is all I need\nYour shoulder close enough to breathe\nDon't let the road run out on me\nDon't let the road run out\n\n[outro]\n(Transition: Final chorus ends on a sustained chord, instrumental layers begin to fade out one by one.)\n(Melody-Contour: (Ad-libs) Improvised, descending vocal phrases; fading out with heavy reverb.)\n(Vocal-Perf: Soft vocal ad-libs ('one more exit'), fading with a long reverb tail.)\n(Inst: Drums and bass fade first, leaving shimmering synth pads and delayed guitar notes that echo into silence.)\n(Mix: Gradual fade out, reverb tails become more prominent as dry signals disappear.)\n(Chords: E - A - E)\nOne more exit\nJust one more",
  "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：黄昏时分沿海公路的光感——最底层是深沉的靛蓝灰，中间层渗入一道灼烧的琥珀橙与暗玫瑰金，最顶层漫开淡雾感的米白，整体传递出「快到终点却主动放慢」的悬停感与温热的不舍。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。",
