  "prompt": "Genre: Dance-Pop, Hip-Hop, Euro-pop; BPM: 125; Key: F# Major; Rhythm: Syncopated dance-pop groove with a strong backbeat on 2 & 4, driven by 16th-note hi-hats.; Instruments: Bright digital piano, Saw-wave lead synth, Subby synth bass, Trance-gate pad, Tight programmed kick; Vocals: Dual Male vocals; one rhythmic, aggressive rap flow and one clean, emotive pop tenor; lush background vocal stacks.; Mood: The feeling of walking home in the cold rain after a fight, streetlights blurring through tears, the city's noise a distant hum against the frantic pounding in your chest.; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Vocals forward, punchy low-end, wide stereo synths, dynamic contrast between verse and chorus.; Highlight: The abrupt shift from the final, spat-out rhythmic rap phrase into the soaring, wide-open piano hook of the chorus, creating a powerful emotional whiplash from anger to regret.",
  "title": "旧密码",
  "lyrics": "[intro]\n(Mix: Punchy sub-bass, prominent vocal-range mids, crisp synth highs. Wide stereo field. Tight bus compression. Gated reverb on snare.)\n(Inst: Bright digital piano plays iconic arpeggiated riff. Filtered drum loop enters. Subby synth bass pulse.)\n(Vocal-Perf: Rhythmic, half-spoken, half-rapped. Close-mic'd with slapback delay.)\n(Hook-DNA: Piano motif is a syncopated 16th-note pattern; anchors on the 5th, creating anticipation; repeats with filter modulation.)\n(Melody-Contour: Piano riff has an arch shape, ascending a minor 3rd then descending.)\n(Melody-Rhythm: Vocal phrases start on the upbeat, push-pull against the straight beat.)\n(Chords: B - C# - D#m - B)\n我还记得那个密码\n六位数\n你生日的顺序\n我没改\n\n[verse]\n(Inst: Full beat kicks in. Driving kick, snare on 2&4. 16th hi-hats. Piano continues. Pizzicato synth strings add rhythmic texture.)\n(Vocal-Perf: Shifts from aggressive rap flow to smooth, emotive tenor singing. Dynamic build.)\n(Melody-Contour: Rap is rhythm-focused. Sung part has a descending scalar line, conveying resignation.)\n(Melody-Rhythm: Sung melody is more legato, holding notes over the bar line, contrasting with the staccato rap.)\n(Chords: B - C# - D#m - B)\n外卖到了按门铃\n我愣了一秒才起身\n屏幕亮着你的头像\n置顶未删\n这算哪门子坚强\n手机滑开又锁上\n骗自己说只是懒\n其实是怕\n翻到聊天记录最底端\n三月十四号 你说"晚安"\n那是你发给我的最后一条\n我回了 你没看\n\n[chorus]\n(Mix: Wider stereo image. Parallel compression on drums for more punch.)\n(Inst: Saw-wave lead synth doubles piano melody. Trance-gate pad adds energy. Lush string pads underneath.)\n(Vocal-Perf: Powerful chest belting on lead vocal. Lush background vocal stacks harmonize key phrases.)\n(Hook-DNA: Main vocal hook is a syncopated phrase starting on the 'and' of 4, resolving on beat 3 of the next bar; anchors around the tonic; repeats with slight melodic variation.)\n(Melody-Contour: Ascending leap of a perfect 4th on the main hook, creating an emotional lift.)\n(Melody-Rhythm: The hook's rhythm is a memorable, driving syncopation that becomes the song's signature.)\n(Melody-Harmonic-Tension: Melody lands on the major 7th over the subdominant (IV) chord, creating a moment of bright tension before resolving down to the 6th.)\n(Chords: G#m - C# - F# - D#m)\n我还留着你的旧密码\n打开又关上 反复折磨\n明明已经两个世界了\n明明已经彻底放手了\n我还留着你的旧密码\n改掉多简单 就是不舍\n六个数字锁住了什么\n锁住我不敢承认的懦弱\n\n[verse 2]\n(Inst: Beat strips back slightly. Piano and bass are prominent. Hi-hats filtered.)\n(Vocal-Perf: More introspective rap delivery. Focus on rhythmic complexity.)\n(Melody-Contour: Rhythm-focused, pitch variation follows natural speech patterns.)\n(Melody-Rhythm: Intricate 16th-note flows, weaving in and out of the beat's pocket.)\n(Chords: B - C# - D#m - B)\n你走之前搬走了几箱\n独剩一个你买的摆件\n我说不喜欢 从没放好位置\n现在摆在最显眼的窗台边\n朋友问我过得怎么样\n我说挺好 声音平坦\n倒完一杯水忘了喝\n坐到天亮\n\n[bridge]\n(Inst: Drums drop out. Sustained synth pads and piano chords create a spacious, atmospheric texture.)\n(Vocal-Perf: Softer, more vulnerable delivery, rising in intensity.)\n(Melody-Contour: Ascending line that builds tension towards the final chorus.)\n(Melody-Rhythm: Phrases are drawn out, less rhythmic, more free-flowing over the pad.)\n(Melody-Harmonic-Tension: Melody deliberately avoids the root, hovering on the 2nd and 6th over a static dominant chord, creating unresolved tension that begs for the chorus to land.)\n(Chords: Bmaj7 - Bbm7 - G#m7 - C#sus4 - C#)\n你现在过得好吗\n有没有人替你把灯留着\n我想问 又怕答案\n比沉默更让我无法消化\n也许我只是 还没准备好\n把那六个数字 永远清零掉\n\n[chorus]\n(Mix: All layers in. Maximum width and energy. Vocal ad-libs panned wide.)\n(Inst: All instruments at full intensity. Crash cymbal on the downbeat.)\n(Vocal-Perf: Most powerful vocal delivery. Ad-libs in both rap and singing style are layered over the main vocal.)\n(Hook-DNA: Same as first chorus but with more ad-libs and layers.)\n(Melody-Contour: Same as first chorus.)\n(Melody-Rhythm: Same as first chorus.)\n(Melody-Harmonic-Tension: Same tension-resolution pattern as the first chorus, but feels more conclusive due to the build-up from the bridge.)\n(Chords: G#m - C# - F# - D#m)\n我还留着你的旧密码\n打开又关上 反复折磨\n明明已经两个世界了\n明明已经彻底放手了\n我还留着你的旧密码\n改掉多简单 就是不舍\n六个数字锁住了什么\n锁住我不敢承认的懦弱\n\n[outro]\n(Inst: Beat continues, piano hook fades out, leaving synth pads and a simple bassline.)\n(Vocal-Perf: Fading ad-libs, repeating key phrases softly.)\n(Chords: F#)\n旧密码\n还存在手机某个角落\n我知道该删了\n明天吧\n明天",
  "cover_prompt": "生成一张极简主义的几何光影艺术图片作为无字音乐专辑封面。画面的核心是：一个边缘柔和模糊的圆形锁孔轮廓，半透明，悬浮在从深冷蓝到暗紫灰的水彩渐变背景中，锁孔内隐约透出一缕温热的琥珀色光晕，象征被封存却未熄灭的记忆余温。画面必须展现出微妙的高级材质肌理，特别是类似水彩晕染（Watercolor texture）或粗糙艺术纸张的触感。整体构图极度克制、留白（Minimalistic composition），注重光与影的柔和交错（Light and shadow interplay）。强烈要求：画面必须保持极致的安宁与静谧（Calm and serene），除了基础的、柔焦的简单几何图形（如模糊的圆、半透明的方块或柔和的线条）外，绝对不要出现任何复杂的现实物体、风景或人物！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！绝对不要生成人物轮廓。传达出一种充满诗意、呼吸感与冥想空间的视觉感受。",
