  "lyrics": "[intro]\n(Chords: Gmaj7 - Em7 - Am7 - D7sus4)\n(Inst: Solo grand piano, arpeggiated chords, spacious feel. Vocal ad-lib enters.)\n(Motif-Anatomy: Simple, ascending piano arpeggio establishes the harmonic theme.)\n(Phrase-Structure: Free-form vocal run over a 4-bar piano loop.)\n(Contour-&-Range: Breathy, mid-range falsetto ad-libs.)\n(Vocal-Perf: Improvised, soulful vocal run, light and airy.)\n(Mix: Piano centered, wide reverb. Vocal has a long reverb tail.)\n\n[verse]\n(Chords: Gmaj7 - Em7 - Cmaj7 - D7sus4)\n(Inst: Soft, live drum kit enters with cross-stick snare. Clean electric bass plays root notes. Piano continues.)\n(Motif-Anatomy: Conversational, mostly stepwise melodic movement.)\n(Phrase-Structure: Symmetrical 4-bar phrases, relaxed delivery.)\n(Contour-&-Range: Low-to-mid register, intimate chest voice.)\n(Vocal-Perf: Gentle, slightly raspy delivery, telling a story.)\n(Mix: Vocals are upfront and dry, drums and bass sit warmly underneath.)\nI kept the voicemails after you were gone\nPlayed them on the highway just to feel less lost\nThe radio kept selling me some perfect version of moving on\nBut I was bargaining with every exit sign I crossed\n(Transition: Subtle cymbal swell and bass walk-up.)\n\n[pre-chorus]\n(Chords: Am7 - Gmaj7/B - Cmaj7 - D7sus4)\n(Inst: Intensity builds slightly, hi-hat opens up.)\n(Motif-Anatomy: Melody begins to ascend, creating tension.)\n(Phrase-Structure: Two longer, building phrases leading to the chorus.)\n(Contour-&-Range: Ascending line from chest voice towards upper register.)\n(Vocal-Perf: More sustained notes, growing in volume and intensity.)\n(Mix: Strings begin to fade in quietly in the background.)\nThey told me time would iron out the crease\nThat distance is a medicine for grief\nBut I've been running long enough to know\nThere's no horizon wide enough to bring me peace\n(Transition: Drum fill into the chorus. Strings swell to full volume.)\n\n[chorus]\n(Chords: Gmaj7 - Bm7b5/F# - Em7 - A7 - Am7 - D7sus4 - Gmaj7)\n(Sound-Design: Lush string section arrival, background harmony vocals enter.)\n(Inst: Full drum kit, piano plays bigger block chords, strings provide harmonic pad.)\n(Motif-Anatomy: Soaring, anthemic melody with a powerful rhythmic hook on \"If I ain't got you\".)\n(Phrase-Structure: Iconic 4-bar resolution with melismatic extensions on the final words.)\n(Contour-&-Range: Dramatic leap of nearly an octave into a powerful, sustained belt.)\n(Vocal-Perf: Full-power belting, rich vibrato, signature R&B melismatic runs.)\n(Mix: Wide stereo image, vocals sit on top of the full arrangement.)\nPull me back down\nI've been floating in the wreckage of before\nYou're the only frequency\nthat cuts straight through the static and the noise\nEvery other voice just echoes\nEvery other touch feels like a door\nLocked from the inside, baby\nAnd you hold the only key I'm looking for\n(Transition: Strings hold a high note, drums simplify.)\n\n[verse]\n(Chords: Gmaj7 - Em7 - Cmaj7 - D7sus4)\n(Inst: Arrangement drops back down to piano, bass, and simple drums.)\n(Motif-Anatomy: Returns to the conversational melody of the first verse.)\n(Phrase-Structure: Symmetrical 4-bar phrases.)\n(Contour-&-Range: Back down to intimate, low-register chest voice.)\n(Vocal-Perf: Soft, reflective tone.)\n(Mix: Dynamic shift creates space after the big chorus.)\nI tried the remedy they bottle up in nightclubs\nLaughed too loud at tables full of pretty conversation\nWent back to the version of myself before you knew me\nStood in my old bedroom like a stranger at a station\n(Transition: Bass walk-up.)\n\n[pre-chorus]\n(Chords: Am7 - Gmaj7/B - Cmaj7 - D7sus4)\n(Inst: Dynamics begin to build again.)\n(Vocal-Perf: Growing intensity, pushing more air.)\n(Mix: Strings re-enter, swelling.)\nBut familiar streets felt foreign in my mouth\nAnd every laugh I faked just pointed further south\nToward the undeniable\nThe gravity I keep on trying to outrun\n(Transition: Big drum fill.)\n\n[chorus]\n(Chords: Gmaj7 - Bm7b5/F# - Em7 - A7 - Am7 - D7sus4 - Gmaj7)\n(Sound-Design: Strings and BVs are even more prominent.)\n(Inst: Full, powerful arrangement.)\n(Motif-Anatomy: Soaring, anthemic melody with powerful rhythmic hook.)\n(Phrase-Structure: 4-bar resolution with even more elaborate melisma.)\n(Contour-&-Range: Powerful high belt.)\n(Vocal-Perf: Even more emotional and powerful than the first chorus, adding complex runs and ad-libs.)\n(Mix: The biggest, most powerful point in the song's mix.)\nPull me back down\nI've been floating in the wreckage of before\nYou're the only frequency\nThat cuts straight through the static and the noise\nEvery other voice just echoes\nEvery other touch feels like a door\nLocked from the inside, baby\nAnd you hold the only key, the only key, the only key\n(Transition: Music sustains, then drops out leaving just piano and vocal.)\n\n[outro]\n(Chords: Gmaj7 - Em7 - Cmaj7 - D7sus4)\n(Inst: Arrangement becomes sparse, focusing on piano and eventually fading.)\n(Motif-Anatomy: Free-form vocal improvisation over the verse chord progression.)\n(Phrase-Structure: Asymmetrical, flowing ad-libs.)\n(Contour-&-Range: Dynamic runs across the entire vocal range, from breathy lows to high falsetto.)\n(Vocal-Perf: Highly emotional, improvisational ad-libs and runs, full of passion.)\n(Mix: Instruments fade out, leaving a final, reverb-laden piano chord and vocal run.)\nPull me back down\nI've been floating in the wreckage of before\nYou're the only frequency\nThat cuts straight through the static and the noise\nEvery other voice just echoes\nEvery other touch feels like a door\nLocked from the inside, baby\nAnd you hold the only key I'm looking for\nLet me land, let me land, let me land in you\nBaby you're the ground I've been reaching for\n",
  "cover_prompt": "生成一张极简主义的抽象环境光晕（Ambient Aura）图片作为无字音乐专辑封面。画面的核心色彩组合与情绪倾向是：深邃的靛蓝与暗紫在画面中央被一道温柔的铜金色光晕穿透，仿佛某种沉重的漂浮状态中忽然出现了一个引力核心——冷与暖在边缘处缓慢渗透融合，既有失重的空旷感，又有即将落地的温度。画面完全由纯粹的色彩构成，采用极度的柔焦（Soft focus）和重度模糊效果（Blurred effect），使得不同颜色之间产生极其平滑、如丝绸般的无缝过渡。整体质感极致平滑细腻（Smooth texture），没有任何杂质。强烈要求：这是一张彻底抽象的现代色彩场（Color Field）作品，绝对不要出现任何具体的物体、几何图案或锐利的边缘！不需要任何胶片颗粒感！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，不要生成人物轮廓！传达出一种极其平静、舒缓、现代且充满呼吸感的氛围。",
