  "lyrics": "[intro]\n(Chords: Cm - Ab - Eb - Gm)\n(Sound-Design: Sound of a slow-moving train on tracks, distant wind)\n(Inst: A breathy, melancholic Dizi flute enters, playing a simple, memorable pentatonic melody; wide, atmospheric synth pads swell gently underneath)\n(Mix: Dizi is the focus, centered and dry with a long reverb tail; pads are wide and distant, establishing a vast space)\n\n[verse]\n(Chords: Cm - Ab - Eb - Gm)\n(Transition: Train sounds fade back; Dizi melody resolves, leaving space for the vocal to enter)\n(Vocal-Perf: Gentle, clear, conversational tone; syllable-precise delivery; natural, unforced phrasing; storytelling feel)\n(Inst: A simple, slow electronic beat starts (kick on 1 & 3, snare on 2 & 4); clean sub-bass follows the root notes; sparse, clean electric guitar arpeggios add harmonic texture)\n(Mix: Vocal is centered, intimate, and upfront; the rhythm section sits comfortably behind the vocal, providing a steady pulse)\n羊群散了以后\n牧歌还剩几句\n年少时许下的誓\n沙子埋了也忘记\n\n[chorus]\n(Chords: Ab - Eb - G - Cm)\n(Transition: Synth pads swell in volume and width, lifting the energy for the chorus)\n(Vocal-Perf: Voice becomes stronger, more resonant in the chest; melody soars on the hook phrase; controlled vibrato on the final word of each line)\n(Melody-Contour: Lyrical arch, ascending to a memorable peak on \"那么静\"; phrases resolve clearly on pentatonic chord tones)\n(Inst: Dizi re-enters, playing a subtle counter-melody that echoes the vocal line; drum beat becomes slightly more defined with soft hi-hats)\n我回不去了\n草原不认识我了\n我回不去了\n那片天也换了颜色\n\n[verse]\n(Chords: Cm - Ab - Eb - Gm)\n(Transition: Dizi and pads recede, creating a dynamic drop back to the verse's intimacy)\n(Vocal-Perf: Returns to the gentle, storytelling delivery of the first verse, maintaining clarity and emotional directness)\n(Inst: Rhythm section continues its simple, steady groove; electric guitar plays slightly more melodic fills between vocal phrases)\n(Mix: Focus returns squarely to the close-mic'd vocal)\n额吉的声音\n越来越像一场梦\n我追着城市的光\n一步步走得太远\n\n[chorus]\n(Chords: Ab - Eb - G - Cm)\n(Transition: A smooth but powerful swell into the final chorus; all instrumental elements build together)\n(Vocal-Perf: Most powerful and emotional delivery of the song; sustained high notes are open and clear; conveys a sense of cathartic release and solitude)\n(Inst: Dizi plays the main hook melody in unison with the vocal for maximum impact; synth pads are at their fullest and widest; soft cymbal crashes on the downbeats for emphasis)\n(Mix: A full soundscape, but the vocal remains clearly on top of the mix, never overwhelmed)\n我回不去了\n草原不认识我了\n我回不去了\n那片天也换了颜色\n\n[outro]\n(Chords: Cm - Ab - Eb - Gm)\n(Transition: All vocals end, leaving the instruments to fade out slowly)\n(Vocal-Perf: Final line \"唱歌的人不时掉眼泪\" is delivered almost as a spoken whisper, full of emotion)\n(Inst: Dizi plays a final, fading phrase of the main melody; the beat and bass fade out, leaving only the synth pads)\n(Sound-Design: The sound of the train and wind gradually returns to the foreground as the music disappears, closing the narrative loop)\n离家的人最怕秋天深",
  "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：一个边缘极度柔和模糊的残月形态，悬浮于从深靛蓝到沉灰绿的水彩渐变背景中，月形之下隐约浮现出一道弧形的低矮地平线，线条若有若无，仿佛草原尽头最后一缕微光正在熄灭。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。",
