  "prompt": "Genre: Hip-Hop Soul / Conscious Rap; BPM: 100; Key: D minor; Rhythm: Lo-fi boom-bap groove with a relaxed, swung 16th-note hi-hat pattern and driving pocket syncopation; Instruments: Sampled breakbeat drum, round synth sub-bass, upright piano w/key noise, punchy horn stab sample, subtle string pad; Vocals: Female. Rhythmic spoken-word rap in verses, shifting to sung lead with lush background vocal stacks in chorus. Warm, raspy, confident timbre; Mood: Giving tough-love advice on a sun-drenched city stoop, the air thick with the smell of pavement after rain.; Production: High-Fidelity, Pristine Radio-Ready Mix with expensive analogue warmth and silky smooth high-end. Prominent low-end, warm mids, centered vocals with tasteful reverb.; Structure: Spoken Intro - Verse 1 - Chorus - Verse 2 - Chorus - Bridge - Outro; Highlight: The entrance of the lush, multi-part soul harmony stack on the first line of the chorus, a sudden cloud of warmth after the pointed, rhythmic verse.",
  "title": "Soft Erosion",
  "lyrics": "[intro]\n(Mix: Warm analog saturation, prominent sub-bass and thuddy kick, crackly snare sits in a pocket of short reverb, vocals centered and clear, slightly recessed piano and horns in the stereo field.)\n(Inst: Upright piano chords, lo-fi drum loop, muted horn sample.)\n(Vocal-Perf: Conversational, rhythmic spoken word.)\n(Chords: Dm7 - G7 - Cmaj7 - Fmaj7)\nMm. You know what soft erosion is?\nIt's not a flood. It's not a storm.\nIt's just... Tuesday. And Wednesday. And the Tuesday after that.\nPay attention.\n\n[verse]\n(Melody-Contour: Primarily rhythmic speech with sharp upward inflections on phrase-ends.)\n(Melody-Rhythm: Delivery pushes and pulls, starting phrases on upbeats, creating tension against the steady boom-bap.)\n(Vocal-Perf: Assertive female rap with a raspy, direct tone.)\n(Inst: Drums, bass, and piano hold the groove, punctuated by horn stabs.)\n(Chords: Dm7 - G7 - Cmaj7 - Fmaj7)\nYou changed your laugh — did you notice? Made it quieter, less teeth\nStarted agreeing with opinions you don't actually believe\nDeleted the playlist that reminded him you had a life before\nNow your whole personality's a footnote, filed and stored\nI watched you Google \"am I asking for too much\" at 2 PM on a workday\nWith a full-time job, a graduate degree, and nothing left to say\nYou narrate his bad behavior to your friends like a defense attorney\nBuilding his case so airtight that you lost track of your own story\nThe fridge has got his leftovers, the shelf has got his brand\nYou reorganized your bookcase so his titles where they land\nLittle by little the apartment stopped smelling like you\nNow even the throw pillows are arranged the way he'd want the view\nThat's not compromise, that's sediment — that's riverbed, not root\nYou've been slowly becoming the background of somebody else's truth\nAnd I say this with both hands open, not a single finger pointed\nBut a woman who's been whittled down can't tell when she's been jointed\n\n[chorus]\n(Hook-DNA: Triplet-feel rhythmic motif on beats 2 and 4; pitch anchor is a descending F-to-D phrase; repetition is a direct A-A-A pattern.)\n(Melody-Contour: Simple descending minor third in lead vocal, with harmony stacks creating a wider arch above.)\n(Melody-Rhythm: Vocal lands squarely on downbeats, contrasting the syncopated verse.)\n(Melody-Harmonic-Tension: Lush background harmonies add 7ths and 9ths, creating tension that resolves on the final word of each line.)\n(Vocal-Perf: Shift to sung lead with thick, multi-part female harmonies in a call-and-response.)\n(Inst: Horns become more melodic, DJ scratches add texture.)\n(Mix: Stereo field widens, vocals get more reverb.)\n(Chords: Dm7 - G7 - Cmaj7 - Fmaj7)\nSoft erosion, soft erosion\nYou don't feel it 'til the shore is gone\nSoft erosion, soft erosion\nGrain by grain, you've been fading along\nFading along, fading along\nFading along, fading along\n\n[verse]\n(Melody-Contour: Rhythmic speech consistent with verse 1.)\n(Melody-Rhythm: Syncopated delivery against the backbeat.)\n(Vocal-Perf: Female rap, maintaining assertive tone.)\n(Inst: Groove remains consistent.)\n(Chords: Dm7 - G7 - Cmaj7 - Fmaj7)\nNow I got something for the one who's doing the eroding\nThinking distance is the same thing as composure, stay in his coding\nHe tips the waiter twenty, opens doors, sends flowers on the schedule\nBut ask him what he's scared of and he goes completely medieval\nShuts it down, changes subject, suddenly the game is on\nEmotional availability treated like a personal con\nShe maps his moods like a meteorologist studies pressure systems\nAdjusting her whole weekend to the weather of his rhythms\nHe calls it giving space — she calls it standing in a hallway\nWaiting for a door to open that he hasn't touched in always\nBeen three seasons of potential, two winters of right around the corner\nThe longer that she waits the more she feels like the foreigner\nAnd I'm not saying he's a villain — some men were never handed tools\nBut inheriting a wound doesn't license you to pass it on as rules\nGrowth isn't something that just happens while your woman holds the ladder\nA man who won't look inward leaves the people closest shattered\n\n[chorus]\n(Hook-DNA: Triplet-feel rhythmic motif on beats 2 and 4; pitch anchor is a descending F-to-D phrase; repetition is a direct A-A-A pattern.)\n(Melody-Contour: Simple descending minor third in lead vocal, with harmony stacks creating a wider arch above.)\n(Melody-Rhythm: Vocal lands squarely on downbeats, contrasting the syncopated verse.)\n(Melody-Harmonic-Tension: Lush background harmonies add 7ths and 9ths, creating tension that resolves on the final word of each line.)\n(Vocal-Perf: Sung lead with thick, multi-part female harmonies in a call-and-response.)\n(Inst: Horns and DJ scratches.)\n(Mix: Stereo field widens, vocals get more reverb.)\n(Chords: Dm7 - G7 - Cmaj7 - Fmaj7)\nSoft erosion, soft erosion\nYou don't feel it 'til the shore is gone\nSoft erosion, soft erosion\nGrain by grain, you've been fading along\nFading along, fading along\nFading along, fading along\n\n[bridge]\n(Melody-Contour: Repetitive chant-like phrase on a flat pitch plateau.)\n(Melody-Rhythm: Hypnotic, syncopated vocal rhythm creates a mantra-like feel.)\n(Melody-Harmonic-Tension: Tension builds through repetition over a static harmony, withholding melodic resolution to build anticipation.)\n(Vocal-Perf: Layered, cautionary chant.)\n(Inst: Drums and bass strip back to focus on vocals.)\n(Mix: Narrows to a more focused, centered sound.)\n(Chords: Dm7)\nRemember who you were, remember who you were\nRemember who you were, remember who you were\nRemember who you were, remember who you were\nRemember who you were, remember who you were\n\n[outro]\n(Hook-DNA: Fading repetition of the chorus's core melodic hook.)\n(Vocal-Perf: Sung harmonies and ad-libs fade out, transitioning to candid spoken word.)\n(Inst: Instrumental track fades slowly under vocals.)\n(Mix: Gradual fade out of the music bed, leaving unfiltered studio chatter.)\n(Chords: Dm7 - G7 - Cmaj7 - Fmaj7)\nSoft erosion, soft erosion\nYou don't feel it 'til the shore is gone\nFading along, fading along\n(The version of you that existed before you started shrinking — she's still in there.)\n(This isn't about leaving. It's about remembering you're allowed to take up space.)\n",
  "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：以大地赭色与消退的沙灰为主调，上方是一层浓重、沉实的赭土棕，颜料厚积如压迫，向下逐渐稀释渗入一片风化的灰白——不是纯白，是被日光长年漂洗后的骨白，带着细微的裂隙感。两层之间有一条极细的锈橙过渡带，像海岸线在低潮时刻露出的湿沙痕迹。整体传达一种缓慢消磨、无声流失的情绪，不是剧烈的破碎，而是长时间温水中的软化与退缩。\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。",
