  "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 Signal",
  "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)\nLeft my jacket on the chair you always used to take\nOrdered something that I knew that you would hate\nThe menu's still the same, the ceiling fan still breaks\nOn the second spin — nothing changed, everything aches\nYour contact's unsaved but I know all seven digits still\nSomebody tell me when this habit gets fulfilled\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.)\nI put the phone face-down, count to eight and breathe\nAnd somewhere in the silence I can almost feel you leave, so\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 keep the salt, you take the sea\nEvery warm and weightless thing you gave away from me\nStay a little, stay a while\nI'm still learning how to lose you with a straight-line smile\nGhost of a good thing, salt and signal\nYou were the wave I couldn't outrun on the shore\nStay a little, stay a while\nI'm still reaching for a door you closed before\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)\nFound a playlist on my old laptop, unopened since May\nFour hours long, every song something you'd say\nI skipped ahead to where I thought it wouldn't sting\nHit a track at two forty-three — same everything\nAnd the Wi-Fi cuts like it always did at noon\nAnd I'm buffering again inside an empty room\n\n[pre-chorus]\n(Mix: Dynamic drop repeats, building tension again.)\n(Inst: Kick drum and vocal.)\n(Vocal-Perf: Breathy and anticipatory.)\nI hold the earbud in one ear, the other side is gone\nStill trying to divide a stereo into one, so\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 the static play, let it play\nLet the static play, let it play\nLet the static play, let it play\nLet the static play, let it play\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 keep the salt, you take the sea\nEvery warm and weightless thing you gave away from me\nStay a little, stay a while\nI'm still learning how to lose you with a straight-line smile\nGhost of a good thing, salt and signal\nYou were the wave I couldn't outrun on the shore\nStay a little, stay a while\nI'm still reaching for a door you closed before",
