  "prompt": "Genre: Commercial Dance-Pop with Tropical House undertones; BPM: 99; Key: C# Minor; Rhythm: Relaxed, syncopated dance groove with a deep pocket; kick on 1 & 3, syncopated off-beat claps, and a driving sub-bass line providing the main forward motion; Instruments: Pitched vocal sample hook w/delay, deep sub-bass synth, warm analogue pads, tight electronic drums, layered finger snaps; Vocals: Female, youthful breathy tone in verses, clear and supported chest voice in chorus, conversational rhythmic phrasing, lush background vocal stacks; Mood: Standing still in the middle of a pulsing dance floor, colorful lights sweeping over faces, feeling a sudden moment of clarity amidst the joyful chaos; Highlight: The moment after the pre-chorus builds anticipation, where instead of a belted vocal, the beat drops into the sparse, catchy pitched-up vocal sample hook, subverting expectations with a minimalist, infectious pop earworm.",
  "title": "Soft Signal",
  "lyrics": "[intro]\n(Mix: High-Fidelity, Pristine Radio-Ready Mix. Wide stereo image, prominent but controlled sub-bass, clean mids, silky smooth high-end. Light sidechain compression on pads from kick.)\n(Inst: Pitched vocal chop melody, warm sustained synth pads, pulsing sub-bass, shakers.)\n(Chords: C#m - A - E - B)\n\n[verse]\n(Hook-DNA: Conversational rhythmic motif; short phrases with frequent pauses; lands consistently on downbeats; builds to a more legato, tension-building phrase at the end.)\n(Melody-Contour: Mostly stepwise motion within a narrow range, ascends a minor third for the final line leading to chorus.)\n(Melody-Rhythm: Vocal phrases start on beat 1, syncopated staccato pattern of eighths and sixteenths, creating a tight pocket with the groove.)\n(Vocal-Perf: Intimate close-mic and breathy delivery, moving to a more projected, sustained tone.)\n(Inst: Groove enters; deep kick, layered snaps on 2 & 4, clean sub-bass line, pads continue.)\n(Chords: C#m - A - E - B)\nYou text me back in lowercase\nTwo words, no period, no grace\nI read it seven times just in case\nWhat does it mean\nI screenshot it, send it to her\nShe says girl you're overthinking for sure\nBut something in the silence before\nHad me believing\nThat you — you — you\nYeah you left that message on read\nAnd I'm replaying every word that you said, you said\nOh oh\n\n[chorus]\n(Hook-DNA: Core vocal hook on title phrase; syncopated rhythm starts on the 'and' of 4; resolves on beat 3 of the second bar; repeats with slight variation.)\n(Melody-Contour: Descending arch shape, starting on the 5th and resolving down to the root.)\n(Melody-Rhythm: A long, syncopated phrase that floats over two bars, contrasting with the verse's short phrasing.)\n(Melody-Harmonic-Tension: Melody lands on the 7th over the IV chord (A), creating a brief, sweet tension before resolving downwards over the I chord (C#m).)\n(Vocal-Perf: Shifts to supported, open chest voice; lush background vocal stacks enter with harmonies and \"oh-oh\" counter-melodies.)\n(Mix: Wider stereo field. Drums gain punch from parallel compression.)\n(Inst: Pitched vocal chop hook re-enters as a counter-melody.)\n(Chords: C#m - A - E - B)\nI — I — I — I keep catching every soft signal you send\nGrasping at a thread that might bend\nWant something real to begin\n\n[interlude]\n(Inst: Pitched vocal chop hook is the focus. Bass and drums carry the groove.)\n(Vocal-Perf: Breathy, heavily effected ad-libs, \"oh-oh\" and \"Like oh\".)\n(Mix: Energy dips slightly from chorus, reverb on vocal chop more prominent.)\n\n[verse]\n(Vocal-Perf: Delivery is more confident and slightly louder than the first verse.)\n(Inst: A subtle 16th-note hi-hat pattern enters, adding momentum.)\n(Chords: C#m - A - E - B)\nYou laugh a little longer with me\nBrush my hand so casually\nThen act like it was nothing, and leave\nJust like that\nYour playlist lands in my suggestions\nAlgorithm answering my questions\nOr maybe I'm just building confessions\nOut of thin air\nThat's why I — I — I\nYeah I keep catching every soft signal you send\nGrasping at a thread that might bend oh oh\n\n[bridge]\n(Melody-Harmonic-Tension: Melody becomes a rhythmic chant on a near-monotone pitch (the root), creating static tension against the shifting IV and V chords underneath, building anticipation for the final chorus release.)\n(Vocal-Perf: Rhythmic, chant-like delivery. Layered vocals create a gang vocal/crowd effect.)\n(Inst: Drums simplify to just kick and snaps, pads become more prominent, creating space.)\n(Chords: A - A - B - B)\nMaybe it's the way your voice drops low\nMaybe it's the pause before you go\nEvery maybe keeps me in this undertow\nLike oh\nI've been holding my breath since I don't know when\nWaiting on a maybe to turn into then\nTell me if it's real or let me breathe again\n\n[chorus]\n(Hook-DNA: Core vocal hook on title phrase; syncopated rhythm starts on the 'and' of 4; resolves on beat 3 of the second bar; repeats with slight variation.)\n(Melody-Contour: Descending arch shape, starting on the 5th and resolving down to the root.)\n(Melody-Rhythm: A long, syncopated phrase that floats over two bars, contrasting with the verse's short phrasing.)\n(Melody-Harmonic-Tension: Melody lands on the 7th over the IV chord (A), creating a brief, sweet tension before resolving downwards over the I chord (C#m).)\n(Vocal-Perf: Most powerful delivery; prominent ad-libs weave around the main vocal.)\n(Mix: Maximum width and impact. Vocal stacks are loudest here.)\n(Inst: Full arrangement with all layers present.)\n(Chords: C#m - A - E - B)\nWant something real to begin\nI keep catching every soft signal you send, want something real to begin\n\n[outro]\n(Inst: Pitched vocal chop hook repeats and filters out. Beat deconstructs, leaving only pads and vocal delay.)\n(Vocal-Perf: Final phrase \"Want something real to begin\" is repeated, fading with a long reverb tail.)",
