  "prompt": "Genre: Tropical Pop; BPM: 96; Key: C# Minor; Rhythm: A subtle dancehall-inspired groove with a four-on-the-floor kick, driven by a syncopated marimba-pluck melody. Percussion is sparse, emphasizing the off-beats.; Instruments: Dry marimba-pluck synth (close-mic'd, fast decay), percussive acoustic guitar slaps, clean sub bass following root notes, punchy electronic kick drum; Vocals: Male tenor with a rhythmic, semi-rapped verse delivery and a relaxed, full chest voice in the chorus. Features lush background vocal stacks and crisp rhythmic ad-libs.; Mood: The warm, low light of a beachside bar after midnight, condensation on a cold glass, the rhythm of the music felt more than heard.; Highlight: The pre-chorus dynamic shift where most instruments drop out, leaving only the vocal and a four-on-the-floor kick, creating a vacuum of tension before the melody enters.",
  "title": "Salt and Static",
  "lyrics": "[intro]\n(Mix: High-fidelity, sparse mix. Prominent, centered sub-bass and dry lead synth. Percussion panned wide but kept dry. Tight master bus compression for radio punch. Minimal reverb, focuses on intimacy.)\n(Inst: Dry marimba-pluck synth, subtle kick drum, finger snaps.)\n(Hook-DNA: Syncopated 16th-note motif that circles the root and 5th of each chord; four-bar loop repeated.)\n\n[verse]\n(Inst: Percussive acoustic guitar slaps enter. Sub bass becomes more prominent.)\n(Vocal-Perf: Rhythmic, semi-rapped, conversational male vocal. Close-mic'd and intimate.)\n(Melody-Rhythm: Phrases start on the upbeat of 1, syncopated against the steady kick.)\n(Chords: C#m - F#m - A - B)\nPhone on silent, screen face-down beside the sink\nBeen two weeks since I unpacked\nThe landlord left a note about the leaking pipe\nI read it twice and tossed it back\nThere's a half-eaten takeout on the counter going cold\nAnd the TV running just for sound\n\n[pre-chorus]\n(Mix: Instrumentation drops out, creating dynamic vacuum.)\n(Inst: Kick drum only, reverb tail from previous section.)\n(Vocal-Perf: More melodic, breathy, builds anticipation.)\n(Melody-Contour: Mostly stepwise motion, small ascending line.)\nAnd somewhere in the static I heard your voice again\nA voicemail I forgot to erase — and I'm singing like\n\n[chorus]\n(Mix: Wider stereo image. Added background vocal layers.)\n(Inst: All elements return, layered claps added.)\n(Vocal-Perf: Fuller chest voice, layered with lush harmony stacks.)\n(Hook-DNA: Long sustained note on 'shape' followed by faster 16ths on 'of you'; phrase resolves strongly to the tonic on 'body'; A-B-A-C structure.)\n(Melody-Harmonic-Tension: Melody sustains the 2nd (D#) over the C#m chord on 'shape', creating a sweet tension before resolving down.)\n(Chords: C#m - F#m - A - B)\nI still know every word you said\nEvery laugh, every long pause, salt and static in my head\nCome on now, let it fade away\nMaybe I'm stubborn, don't blame me, hey\nI still keep what we had\nEvery silence that stretched out and pulled me back to you\nCome on now, let it fade away\nCome — come on now, let it fade away\n\n[verse]\n(Inst: Arrangement remains consistent with first verse, maintaining groove.)\n(Vocal-Perf: Returns to conversational, rhythmic delivery.)\n(Melody-Rhythm: Vocal phrasing continues to play against the beat with syncopation.)\n(Chords: C#m - F#m - A - B)\nI drove past the parking lot where we used to sit\nOn the hood with convenience store ice cream\nYou always got the green tea, I got something wrong\nWe'd argue till it turned to laughing\nThe receipt's still in my jacket from the last time we were out\nInk faded but the crease is sharp and clean\n\n[pre-chorus]\n(Mix: Dynamic drop repeats, building tension again.)\n(Inst: Kick drum and vocal.)\n(Vocal-Perf: Breathy and anticipatory.)\nAnd I sat there in the parking lot, engine running low\nA playlist that I built for you still playing — and I'm singing like\n\n[bridge]\n(Inst: Texture becomes softer, slightly filtered feel.)\n(Vocal-Perf: Repetitive, chant-like, stacked vocals building in intensity.)\n(Melody-Harmonic-Tension: A simple repeated melodic motif (G#-G#-F#-E) creates a hypnotic effect over the static chord progression, building tension through repetition.)\n(Chords: C#m - F#m - A - B)\nLet it go, let it go, let it go\nLet it go, let it go, let it go\nLet it go, let it go, let it go\nLet it go, let it go, let it go\n\n[chorus]\n(Mix: Maximum energy, ad-libs added in background layers for texture and rhythm.)\n(Vocal-Perf: Most energetic delivery, includes ad-libs and subtle vocal runs.)\n(Hook-DNA: The main 'shape of you' hook is layered with the 'Oh-I' vocal motif and bridge ad-libs.)\n(Melody-Harmonic-Tension: Chorus vocal melody tension is heightened by the energy of the additional vocal layers.)\n(Chords: C#m - F#m - A - B)\nI still know every word you said\nEvery laugh that dissolved into something I can't shed\nAlthough the mornings come and go\nI'm still caught in the salt and static undertow\nThat voicemail never got erased\nAnd your green tea order's saved inside my phone to this day\nEvery corner of this city echoes you\nI'm still lost in the salt and static, through and through",
  "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：一个边缘柔和模糊的椭圆形光晕，处于从深灰蓝到哑光珊瑚色的水彩渐变背景中，光晕内部透出一种温热的琥珀黄，仿佛夜晚热带海边酒吧透过雾气散射的灯光，中间有一层极薄的白噪点质感叠加，暗示"静电"与记忆的模糊边界。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。",
