  "lyrics": "[intro]\n(Chords: Am - G - C - F)\n(Inst: Filtered piano melody, soft synth pads swelling, distant 808 kick thumps)\n(Mix: Narrow stereo field, slowly widening)\n(Sound-Design: Subtle vinyl crackle)\n\n(Transition: Filter opens on piano, sub-bass fades in smoothly)\n[verse]\n(Chords: Am - G - C - F)\n(Inst: Reverb-heavy piano chords, deep sub-bass on root notes, steady 16th-note hi-hats enter quietly, sparse kick on 1)\n(Vocal-Perf: Intimate, breathy, close-mic'd whisper, minimal vibrato)\n(Melody-Contour: Conversational, mostly stepwise motion, low in the vocal range)\n(Melody-Rhythm: Relaxed phrasing, slightly behind the beat)\nSomewhere\nbetween the second glass and 3 AM\nI stopped pretending\nThat the quiet didn't cut\nLike I was built to fit a life\nthat wasn't mine\n\n(Transition: Snare enters, synth pad layers build, subtle reverse cymbal swell)\n[pre-chorus]\n(Chords: F - C - G - Am)\n(Inst: Full beat enters, snare is more prominent, synth pads increase in volume and brightness)\n(Vocal-Perf: Volume increases slightly, more emotional intensity, still airy)\n(Melody-Contour: Ascending line, building anticipation for the chorus)\nI kept my fears inside a practiced smile\nBelieved that disappearing made it all worthwhile\nGave every version of myself to something\nthat was never mine to give\n\n(Transition: Brief pause of drums for one beat before chorus hits)\n[chorus]\n(Chords: C - G - Am - F)\n(Inst: Full beat with prominent kick and snare, layered synth pads create a wide wall of sound, piano arpeggios add movement)\n(Mix: Widest stereo image, vocals have layered harmonies, sub-bass at full volume)\n(Vocal-Perf: Stronger chest voice, more projected, sustained notes with subtle vibrato, layered backing vocals)\n(Melody-Contour: Jumps up a perfect fifth for emotional impact)\n(Hook-DNA: AAB structure; a memorable 4-bar melodic phrase repeats, with the final line acting as a descending resolution)\nI was orbiting someone else's sun\nDrifting further out\nLost before I'd even begun\nI was orbiting someone else's sun\nNowhere left to go\nBut back to who I was\n\n(Transition: Sustained synth pad and reverb tail carries over)\n[verse]\n(Chords: Am - G - C - F)\n(Inst: Arrangement drops back down, but the hi-hats remain more present than in verse 1)\n(Vocal-Perf: Returns to intimate, breathy delivery, but with more resolve)\nSometimes\nI find old notes I wrote when I was twenty-two\nAll that fire\nAll those futures I once swore I'd chase\nNow folded into silence\nhidden in the space\n\n(Transition: Drum fill with rising intensity, synth arpeggio introduced subtly)\n[pre-chorus]\n(Chords: F - C - G - Am)\n(Inst: Arrangement builds again, pads swell, snare becomes more forceful)\n(Vocal-Perf: Intensity builds, a subtle harmony added on the last line)\nI kept my fears inside a practiced smile\nBelieved that disappearing made it all worthwhile\nGave every version of myself to something\nthat was never mine to give\n\n(Transition: More dramatic dropout of all instruments except a sustained pad before the final chorus)\n[chorus]\n(Chords: C - G - Am - F)\n(Inst: Most powerful section. All elements plus a new high-octave piano counter-melody. Cymbals crash on downbeats.)\n(Mix: Maximum width and volume. Vocal ad-libs panned left and right.)\n(Vocal-Perf: Most powerful delivery, full chest voice, noticeable vibrato, emotional ad-libs in background)\n(Hook-DNA: Core melody is identical, but added instrumental and vocal layers create a powerful climax)\nI was orbiting someone else's sun\nDrifting further out\nLost before I'd even begun\nI was orbiting someone else's sun\nNowhere left to go\nBut back to who I was\n\n(Transition: Beat abruptly cuts, leaving only the reverb tail of the piano and vocals to decay)\n[outro]\n(Chords: Am - F - C - G)\n(Inst: Just the reverb-heavy piano playing a simple, melancholic version of the main melody, fading out)\n(Mix: Fades to silence, stereo field narrows)\n(Vocal-Perf: A single, distant, wordless vocal sigh with heavy echo)\n(Sound-Design: Vinyl crackle returns and fades, ends with the soft click of a TV turning off)",
  "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：一个边缘极度柔和的圆形光晕，如同遥远轨道上孤悬的星体，悬浮于从深靛蓝向暗紫灰过渡的水彩渐变背景中，圆形本身呈半透明的冷银白色，与背景之间有一圈若隐若现的晕光边缘。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。",
