  "prompt": "Genre: Indie Pop / Bedroom Pop Ballad; BPM: 105; Key: D Major; Rhythm: Gentle, shuffle-like groove driven by a tight kick and syncopated, brushed snare patterns, creating constant forward motion without being aggressive; Instruments: Dry acoustic drums (close mic), warm electric bass (fingerstyle), clean electric guitar (arpeggios), subtle analog synth pad (swells); Vocals: Female, intimate close-mic and breathy delivery in verses, transitioning to lush background vocal stacks in the chorus; Mood: Sitting on the floor of a sunlit room, leaning against someone you trust completely, a quiet promise hanging in the air that you'll follow them anywhere; Highlight: The moment the chorus hits (0:59), where the lead vocal abruptly shifts from a dry, centered take to wide, lush background vocal stacks, creating a sudden emotional and spatial bloom.",

Vocal-forward, focused low-center (kick/bass), wide guitars creating stereo space. Clean but warm, with subtle tape saturation and controlled high-end.)\n\n[verse]\n(Hook-DNA: N/A)\n(Melody-Contour: Mostly conversational, stepwise motion within a narrow range, subtle descending shape at end of phrases.)\n(Melody-Rhythm: Phrases begin on beat 1, conversational rhythm with natural pauses, closely following the lyrical cadence.)\n(Chords: D - Bm - G - A)\n(Inst: Full drum kit enters with brushed snare; Round, warm electric bass locks with kick drum; Guitar continues arpeggios.)\n(Vocal-Perf: Intimate, breathy, close-mic'd lead vocal with audible vocal fry. Very little reverb, dry and centered.)\n旧毛衣洗了又缩水\n搭在椅背上没人归位\n你的外套还压在我柜底\n像一枚钝针扎进布里\n我不打算把它还你\n也不打算说清楚理由\n只是每次打开柜门的瞬间\n还是会愣在那里\n\n[pre-chorus]\n(Hook-DNA: N/A)\n(Melody-Contour: Gentle ascending line, building tension by climbing from the 3rd to the 5th of the scale.)\n(Melody-Rhythm: More sustained notes than verse, legato phrasing leading into the chorus.)\n(Chords: G - A - D - Bm)\n(Inst: Subtle synth pad swells underneath the main instruments, adding warmth and anticipation.)\n(Vocal-Perf: Vocal intensity increases slightly, moving from breathy tone to a clearer, more supported sound.)\n两个人走散也没什么\n不过是时间偷换了地图\n我以为我已经学会了放\n可手指还记得你的温度\n这件事我瞒不过自己\n\n[chorus]\n(Hook-DNA: Rhythmic motif is a syncopated long-short-long pattern on \"day that I die\"; Anchors on the root note (D) for resolution; Repeats with slight melodic variation to match lyrics.)\n(Melody-Contour: Ascending leap of a perfect 4th on \"I don't know\", followed by a gentle descending arch.)\n(Melody-Rhythm: Vocal phrases start consistently on the upbeat before beat 1, creating an infectious pop earworm feel against the downbeat-driven rhythm section.)\n(Melody-Harmonic-Tension: Melody holds the major 7th over the G chord (IV) for a full beat, creating a moment of bright tension before resolving down to the 6th.)\n(Chords: G - D - A - Bm)\n(Inst: Drums become slightly more impactful; Synth pad is more prominent.)\n(Vocal-Perf: Lead vocal is stronger, supported by lush, wide-panned multi-tracked background vocal stacks singing in tight harmony.)\n(Mix: Stereo field widens significantly with the introduction of backing vocals and synth.)\n我没办法假装忘记你\n没办法把这个洞缝整齐\n时间走啊走 走到什么地方\n还是会绕回到你这里\n绕回到你这里\n像一根留针\n绕回到你这里\n\n[verse]\n(Hook-DNA: N/A)\n(Melody-Contour: Returns to the conversational, narrower range of the first verse.)\n(Melody-Rhythm: Same as first verse, maintaining a storytelling pace.)\n(Chords: D - Bm - G - A)\n(Inst: Arrangement strips back slightly, mirroring Verse 1.)\n(Vocal-Perf: Reverts to the dry, intimate, close-mic'd vocal delivery.)\n超市自动门坏了一半\n我站在感应范围边缘\n想起你说过最讨厌等待\n我们好像一直都在等\n等下一个路口转弯\n等开口却没说的那句话\n等两个人都有勇气的某天\n等来等去等散了\n\n[chorus]\n(Hook-DNA: Rhythmic motif is a syncopated long-short-long pattern on \"say goodbye\"; Anchors on the root note; Repeats with slight melodic variation.)\n(Melody-Contour: Ascending leap of a perfect 4th on \"I don't know\", followed by a gentle descending arch.)\n(Melody-Rhythm: Vocal phrases start consistently on the upbeat before beat 1, driving the energy forward.)\n(Melody-Harmonic-Tension: Melody holds the major 7th over the G chord (IV) for a full beat, creating a moment of bright tension before resolving down to the 6th.)\n(Chords: G - D - A - Bm)\n(Inst: Drums, bass, guitar, and synth pad at full intensity for this section.)\n(Vocal-Perf: Full power lead vocal with prominent, harmonically rich background vocal stacks.)\n(Mix: Maximum width and dynamic impact.)\n我没办法假装忘记你\n没办法把这个洞缝整齐\n时间走啊走 走到什么地方\n还是不想跟你说再见\n\n[bridge]\n(Hook-DNA: N/A)\n(Melody-Contour: A new, higher-register melodic idea with a more plaintive, floating quality.)\n(Melody-Rhythm: Phrases are longer, more legato, stretching over the bar lines.)\n(Melody-Harmonic-Tension: Melody deliberately avoids the root, hovering on the 2nd and 6th over a static chord progression, creating a feeling of suspension and unresolved longing.)\n(Chords: G - A - Dmaj7 - Bm)\n(Inst: Arrangement becomes more sparse; bass holds long root notes, drums simplify to just kick and hi-hat.)\n(Vocal-Perf: Vocal shifts to a softer, almost falsetto-like quality, adding vulnerability.)\n我只是不知道怎么开口\n说我其实一直还在等候\n所以就这样吧 留着就好\n\n[outro]\n(Chords: G - A - D)\n(Inst: Instruments slowly fade out, leaving only the clean electric guitar arpeggio.)\n(Vocal-Perf: Ad-libbed vocal melodies, breathy and improvisational, fade along with the music.)\n(Transition: Final guitar chord rings out with its natural decay.)\n两个人走散也没什么\n不过是时间偷换了地图\n我以为我已经学会了放（像一根留针）\n可手指还记得你的温度（绕回到你这里）\n这件事我瞒不过自己（留着就好）\n还是绕回到你这里",
  "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：一件叠成方块、边缘微微松散的针织毛衣的柔焦轮廓，处于从浅暖米色渐变至朦胧灰蓝的水彩背景中，衣物轮廓边缘被晕染得若隐若现，仿佛记忆正在慢慢模糊但始终未消散。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。",
