  "prompt": "Genre: Neo-Soul / Jazz-Funk Fusion; BPM: 152; Key: B minor; Rhythm: Laid-back half-time groove with a constant 16th-note hi-hat pulse. The kick and syncopated bassline create a deep, head-nodding feel, demonstrating driving pocket syncopation.; Instruments: Fender Rhodes EP with warm tremolo, Lo-fi sampled drum kit with soft kick and dry snare, Warm electric bass played fingerstyle with round tone, Lush synth pad low in the mix for texture, Light tambourine; Vocals: Female lead with a dynamic range from intimate, conversational spoken-word in verses to soulful, melodic R&B singing in choruses, complemented by lush background vocal stacks.; Highlight: The sudden dynamic drop at the start of the bridge where the drums simplify to just kick and hats, and the vocal delivery shifts from full singing to an intimate, half-spoken tone, drawing the listener in closer.",
  "title": "Still Gray Sweater",
  "lyrics": "[intro]\n(Mix: High-fidelity warm analog mix. Prominent, rounded sub-bass and low-mids. Silky smooth high-end. Stereo field is intimate and centered. Light bus compression allows for dynamic breathing room.)\n(Inst: Fender Rhodes plays a syncopated, jazzy chord riff. Lo-fi drum loop enters with a relaxed half-time feel. Round-toned electric bass enters with a melodic counterpoint.)\n\n[verse]\n(Hook-DNA: N/A - conversational delivery)\n(Melody-Contour: Narrow range, speech-like contour, mostly stepwise motion around a few central pitches.)\n(Melody-Rhythm: Syncopated, behind-the-beat phrasing that weaves around the steady drum groove, emphasizing lyrical meaning over melodic structure.)\n(Vocal-Perf: Intimate, close-mic, conversational delivery with rhythmic precision. Almost spoken-word.)\n(Chords: Bm7 - Em7 - Bm7 - Em7 - F#7sus4 - F#7)\n(Inst: Core rhythm section of Rhodes, bass, and drums establishes the groove.)\nI wore the same gray sweater three weeks running\nMicrowaved the same soup, called it good\nTold myself the quiet wasn't cutting\nThrough the noise I never understood\nThen something in the Tuesday light shifted\nFell across the floorboards slow and wide\nAnd I just sat there, completely lifted\nFeeling something soft land deep inside\n\n[chorus]\n(Hook-DNA: Core motif is a syncopated 16th-eighth-eighth pattern on \"long walk a-round\", anchoring on the 5th and resolving to the root on \"park\". Motif repeats twice, then extends into a descending closing phrase.)\n(Melody-Contour: Clear arch shape. Ascends a perfect 4th from F# to B on \"long walk\", then descends through the scale.)\n(Melody-Rhythm: Phrases land solidly on the downbeat, contrasting with the verse's laid-back feel.)\n(Melody-Harmonic-Tension: Melody holds a tense major 7th over the Gmaj7 chord on \"spark\", resolving satisfyingly downwards on the next line.)\n(Vocal-Perf: Shifts to full, soulful singing. Lush background vocal stacks enter, harmonizing key phrases.)\n(Mix: Stereo image widens with backing vocals and a new pad element.)\n(Inst: Subtle, warm synth pad added for harmonic fill and width.)\n(Chords: Bm7 - Em7 - Bm7 - Gmaj7 - F#7sus4 - F#7)\nThis is my soft landing, soft landing\nNo more hard arrivals, no more crash and scatter\nJust my chest expanding, breath unwinding, slowly understanding\nThat the ground beneath me holds\nThis is my soft landing\n\n[verse]\n(Melody-Contour: Returns to a lower, conversational range.)\n(Melody-Rhythm: Vocal delivery again sits back in the pocket, syncopated and relaxed.)\n(Vocal-Perf: Returns to the intimate, rhythmic spoken-word style of the first verse.)\n(Chords: Bm7 - Em7 - Bm7 - Em7 - F#7sus4 - F#7)\nI used to keep my shoulders near my earlobes\nSigned up for every single thing they asked\nStretched so thin I nearly tore right through, though\nSmiling through a face that was a mask\nBut lately I've been leaving dishes soaking\nLetting deadlines breathe a minute more\nSomething in my ribcage finally open\nLike a window I forgot was there before\n\n[chorus]\n(Hook-DNA: Core motif is a syncopated 16th-eighth-eighth pattern on \"long walk a-round\", anchoring on the 5th and resolving to the root on \"park\". Motif repeats twice, then extends into a descending closing phrase.)\n(Melody-Contour: Clear arch shape. Ascends a perfect 4th from F# to B on \"long walk\", then descends through the scale.)\n(Melody-Rhythm: Phrases land solidly on the downbeat, contrasting with the verse's laid-back feel.)\n(Melody-Harmonic-Tension: Melody holds a tense major 7th over the Gmaj7 chord on \"spark\", resolving satisfyingly downwards on the next line.)\n(Vocal-Perf: Full, soulful singing. Lush background vocal stacks are more prominent.)\n(Mix: Stereo image at its widest. Lead vocal has slightly more reverb.)\n(Inst: Synth pad is slightly louder in the mix, filling more space.)\n(Chords: Bm7 - Em7 - Bm7 - Gmaj7 - F#7sus4 - F#7)\nThis is my soft landing, soft landing\nNo more hard arrivals, no more crash and scatter\nJust my chest expanding, breath unwinding, slowly understanding\nThat the ground beneath me holds\nThis is my soft landing\n\n[bridge]\n(Melody-Harmonic-Tension: Melody phrases end on unresolved tones over shifting chords, each phrase trailing off like a held breath before the next one begins, building a weightless suspension above the sparse groove.)\n(Vocal-Perf: Delivery drops to an intimate, half-whispered, speculative tone. Very close-mic'd.)\n(Mix: Narrows significantly. Reverb is reduced. The arrangement becomes sparse and dry, focusing attention on the vocal.)\n(Inst: Drums simplify to just kick and hi-hat. Bass plays a more melodic, walking line.)\n(Chords: Gmaj7 - F#m7 - Em7 - Bm7 - Gmaj7 - F#m7 - C#m7b5 - F#7)\nI don't need to fix it all right now\nI can let the kettle cool\nLeave the unread messages unread\nMaybe being still is its own proof\nMaybe all the rushing was the bruise\nAnd the quiet is the healing coming through\n\n[outro]\n(Vocal-Perf: Soulful, improvisational ad-libs and vocal runs over the main vamp. Fades out gradually.)\n(Inst: The full chorus instrumentation vamps on the Bm7 - Em7 progression and slowly fades.)\n(Mix: Gradual fade to silence over 8 bars, with reverb tails lingering last.)\nSoft landing... soft landing...\nLet it hold you, let it hold...\nNo more crashing through the ceiling\nJust the warmth of coming home...\nSoft landing, oh...",
  "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：一片从深燧石蓝向沙土黄徐徐渗透的色域，中间地带有一层极薄的鹅绒白漫开，像一个疲惫的身体终于触碰到柔软地面的瞬间，整体传递出卸下重量后的温热与静默。\n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。\n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。",
