  "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": "Full Tilt",
  "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 coastal road bends into the amber haze\nYour hand taps the wheel in an absent-minded daze\nNo sign says where this two-lane ribbon ends\nThe speedometer climbs past the point it defends\nYour fingers find the window seam and let the salt wind in\nMy breath goes short — not from the speed but from your skin\nNo exit chosen, no returning lane in sight\nWe burn the last of the daylight\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)\nFloor it one more time, feel the road give way\nFloor it one more time, lungs wide open, stay\nFloor it one more time — I don't care where we land\nAs long as you're the one who's driving with both hands off the plan\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 thought I was chasing something out ahead\nTurns out I was running from the same thing instead\nGoing faster, going nowhere — both were always true\nThe only way I know to flee is straight toward you\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)\nFloor it one more time, feel the road give way\nFloor it one more time, lungs wide open, stay\nFloor it one more time, taste the wind go raw\nFloor it one more time — I don't need to know the law\nFloor it one more time, this is not a race\nFloor it one more time — I just need to see your face\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 ('full tilt'), 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)\nNo destination\nJust the speed and you beside me",
  "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：大面积倾斜的平行曲线群从画面左下角向右上角加速扩张，线条间距从左侧的密集渐变为右侧的稀疏，制造强烈的速度与失重感；主色调为落日琥珀橘与深海蓝的双专色叠印，叠印区域产生暗金色第三色；整体构图向右倾斜约15度，暗示车辆过弯时的重心偏移。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。",
