  "prompt": "Genre: Neo-Soul with 70s R&B and Yacht Rock influences; BPM: 161; Key: A# minor; Rhythm: Relaxed, half-time feel driven by a busy 16th-note hi-hat groove over a tight, syncopated kick/snare pattern. The melodic, walking bassline provides driving pocket syncopation.; Instruments: Dry close-mic'd drums, Round fingerstyle bass, Creamy Rhodes piano, Clean chorus guitar, Deep male choir chant; Vocals: Female, with a smooth, breathy, and soulful timbre, moving between a gentle chest voice and a lighter head voice. Features lush background vocal stacks.; Mood: Sitting on a train watching rain-streaked landscapes blur past, the rhythm of the tracks matching a quiet, internal conversation.; Highlight: The initial, unaccompanied deep male choir chant that establishes a vast, ancient space before the intimate, tight band groove abruptly enters, creating a stark and compelling textural contrast.",
  "title": "Meridian Drift",
  "lyrics": "[intro]\n(Inst: Deep male chant, Dry acoustic drums, Round fingerstyle bass, Creamy Rhodes piano)\n(Mix: Warm, analog-tape feel. Wide stereo image from Rhodes panned left and clean guitar panned right. Bass and kick perfectly centered and punchy. Vocal will be front, center, and relatively dry with a short plate reverb. Prominent mid-range, controlled sub-bass, silky smooth high-end.)\n\n[verse 1]\n(Chords: Bbm - Gb - Ab - Bbm)\n(Vocal-Perf: Intimate, breathy delivery, low in register, close-mic'd feel)\n(Inst: Clean electric guitar enters with subtle arpeggios and chord stabs)\n(Melody-Contour: Predominantly stepwise motion with a descending contour, staying within a narrow range)\n(Melody-Rhythm: Phrases begin on the 'and' of beat 1, creating a relaxed, flowing feel that drifts over the bar line)\nI used to know\nThe shape of you\n\n[verse 2]\n(Chords: Bbm - Gb - Ab - Bbm)\n(Vocal-Perf: Maintains the same intimate delivery, a sense of quiet reflection)\n(Inst: Bass becomes slightly more melodic, connecting the chords with small runs)\n(Melody-Contour: Continues the gentle, descending melodic shape of the first verse)\n(Melody-Rhythm: Slightly more syncopated phrasing, with more space between lyrical lines)\nThe way your shoulder held the morning light\nBefore the coffee cooled, before the fight\nHow the floorboards learned your weight at night\n\n[bridge]\n(Chords: C#maj7 - G# - Bbm)\n(Vocal-Perf: Dynamic intensity builds slightly, moving from breathy to a more supported, clearer tone)\n(Inst: Rhodes piano plays fuller, more sustained chords, creating a harmonic pad)\n(Melody-Harmonic-Tension: Melody floats on the 5th over the C#maj7 (the III chord), creating a bright, suspended feeling that creates anticipation for the tonic resolution in the chorus)\nI keep reaching for a warmth that isn't there\nJust the hollow where you used to fill the air\n\n[chorus 1]\n(Chords: Ebm - Bbm - Ebm - Bbm - Gb - Ab - Bbm)\n(Vocal-Perf: Stronger, full-chest voice on the main phrases. Lush background vocal stacks enter with smooth harmonies)\n(Hook-DNA: Core motif is a syncopated phrase starting on beat 2; melody circles the 5th (F) as its anchor; the motif repeats twice, with the third statement rising a step for variation)\n(Melody-Contour: A distinct ascending leap of a perfect 4th kicks off the main hook, before arching back down)\n(Melody-Rhythm: The main hook lands firmly on beat 2 of each bar, pushing against the backbeat and creating a laid-back but infectious groove)\n(Melody-Harmonic-Tension: The melody holds a sustained 9th over the Ebm (iv chord), creating a rich, soulful tension that resolves gracefully downwards to the root by the end of the phrase)\n(Mix: Stereo image widens. Vocal reverb becomes slightly more noticeable)\nDrifting, drifting past the meridian line\nWhere every mile I'm more and less of mine\nOh, more and less of mine\n\n[chorus 2]\n(Chords: Ebm - Bbm - Ebm - Bbm - Gb - Ab - Bbm)\n(Vocal-Perf: Most powerful and emotive delivery. Lead vocal includes small, soulful ad-libs. Background vocals are more prominent)\n(Hook-DNA: Core motif is a syncopated phrase starting on beat 2; melody circles the 5th (F) as its anchor; the motif repeats twice, with the third statement rising a step for variation)\n(Melody-Harmonic-Tension: The melody holds a sustained 9th over the Ebm (iv chord), creating a rich, soulful tension that resolves gracefully downwards to the root by the end of the phrase)\n(Mix: Drums get a touch of parallel compression for extra punch. Mix is at its widest and most dynamic)\nI gave you something I can't name or reclaim\nAnd the distance only sharpens what remains\nDrifting, drifting past the meridian line\nGrowing into someone I don't yet recognize\n\n[outro]\n(Chords: Bbm - Gb - Ab - Bbm)\n(Vocal-Perf: Fades out with improvised, soulful scatting and melodic ad-libs)\n(Inst: Band vamps on the verse progression. Rhodes takes a final, short melodic solo before a slow fade)\n(Mix: Slow, gradual fade-out over 8 bars, leaving only the reverb tail of the Rhodes at the very end)\nStill drifting\nStill becoming\nPast the line where I was whole\nEvery mile a different soul",
  "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：深沉的赭褐色与暗钴蓝在画布中心缓慢渗透交融，边缘向更低饱和的灰紫过渡，仿佛两种温度的液体在纸面上相遇却无法彻底融合，传递出一种持续位移中的内在疏离感。\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。",
