  "prompt": "Genre: Indie R&B / Lo-fi Pop; BPM: 121; Key: C# Major; Rhythm: Relaxed, slightly behind-the-beat 4/4 groove with a prominent, round kick on 1 & 3 and a soft, reverby snare on 2 & 4, creating a subtle driving pocket syncopation; Instruments: Plucky clean e-guitar (fret noise), Round DI'd e-bass (root notes), Lo-fi acoustic drum kit (pillowy kick), Warm atmospheric synth pad swells; Vocals: Male, soft and breathy tenor with an intimate close-mic delivery, supported by lush background vocal stacks in wide stereo; Mood: Sitting on the edge of a bed in a dimly lit room, city lights blurred through the window, replaying a quiet, significant conversation in your head; Highlight: The sudden drop of the main drum groove at the start of the bridge, leaving only a sparse chordal pulse and the lead vocal, creating a vacuum of space that heightens the lyrical vulnerability.",
  "lyrics": "[intro]\n(Mix: Warm, analog-tape feel. Prominent but pillowy sub-bass. Clear, centered mid-range for vocals/guitar. Silky, rolled-off high-end. Lead vocal dead center, dry, intimate. BGVs and reverbs panned ultra-wide. Gentle bus compression.)\n\n[verse]\n(Chords: C# - G# - A#m - F#)\n(Inst: Sparse clean electric guitar arpeggio; Foundational bassline enters halfway; Simple kick-snare pattern.)\n(Vocal-Perf: Conversational, breathy, close-mic'd tenor. Minimal dynamics.)\nI'll probably be a waste of your time, but who knows?\nChances are I'll step out of line, but who knows?\n\n[pre-chorus]\n(Inst: Bass becomes more melodic; Subtle pad swells underneath.)\n(Vocal-Perf: Intensity lifts slightly; Introducing a single, low harmony layer.)\nLately, you've set up in my mind\nYeah, girl, you, and I like that\n\n[chorus]\n(Chords: C# - F# - A#m - G#)\n(Hook-DNA: Three-part lyrical motif; Rhythm is speech-like, following lyric cadence; Pitches circle the 3rd and 5th, resolving downwards at end of phrase.)\n(Melody-Contour: Gentle arch shape; Melodic peak on the second line; Descends stepwise to resolve.)\n(Melody-Rhythm: Phrases begin on the 'and' of beat 1, creating a relaxed, pull-back feel against the drums.)\n(Melody-Harmonic-Tension: Melody holds the major 7th over the IV chord (F#) for a full beat, creating a sweet, lingering tension before resolving to the root.)\n(Inst: Full drum kit enters; Guitar plays fuller chords instead of arpeggios.)\n(Vocal-Perf: Lead vocal remains intimate, but now surrounded by wide, lush background vocal stacks.)\n(Mix: Stereo image widens significantly with layered BGV pads.)\nLately, I've been thinking that perhaps I am a coward\nHiding in a disguise of an ever-giving flower\nIncompetent steward of all of that sweet, sweet power\n\n[verse]\n(Chords: C# - G# - A#m - F#)\n(Inst: Arrangement thins out, returning to sparse verse 1 texture.)\n(Vocal-Perf: Returns to quiet, conversational delivery.)\nYesterday was feeling so good, now it's gone\nI'd feel like that always if I could, is that wrong?\n\n[pre-chorus]\n(Inst: Bass again becomes more melodic, leading into the chorus.)\n(Vocal-Perf: Slight build in energy, harmonies re-emerge.)\nTell me 'bout the city you're from\nIs it hot? Does it snow there?\n\n[chorus]\n(Chords: C# - F# - A#m - G#)\n(Hook-DNA: Three-part lyrical motif; Rhythm is speech-like, following lyric cadence; Pitches circle the 3rd and 5th, resolving downwards at end of phrase.)\n(Melody-Contour: Gentle arch shape; Melodic peak on the second line; Descends stepwise to resolve.)\n(Melody-Rhythm: Phrases begin on the 'and' of beat 1, creating a relaxed, pull-back feel against the drums.)\n(Melody-Harmonic-Tension: Melody holds the major 7th over the IV chord (F#) for a full beat, creating a sweet, lingering tension before resolving to the root.)\n(Inst: Full instrumentation returns.)\n(Vocal-Perf: Confident lead delivery amidst wide, layered harmonies.)\n(Mix: Dynamic peak of the song; Wide stereo field, parallel compression on drum bus.)\nLately, I've been thinking 'bout my precarious future\nWill you be there with me by my side, my girl, my shooter?\nWho's to say who calculates? Not me, I'm no computer\n\n[bridge]\n(Chords: F#maj7 - A#m7)\n(Melody-Harmonic-Tension: Melody becomes a rhythmic chant on the root and 5th, creating tension through hypnotic repetition over a static two-chord vamp that refuses to resolve to the tonic.)\n(Inst: Drums and main guitar drop out; Replaced by a single, pulsing synth chord and sparse bass.)\n(Vocal-Perf: Delivery becomes more rhythmic, almost spoken; Background vocals create a swirling, atmospheric bed.)\n(Mix: Sudden drop in energy; Mix becomes atmospheric, dominated by reverb and delay throws.)\nIs it a crime to be unsure?\nIn time, we'll find if it's sustainable\nYou're pure, you're kind, mature, divine\nYou might be too good for me, unattainable\n\n[outro]\n(Chords: C# - G# - A#m - F#)\n(Inst: Sparse verse 1 instrumentation returns; Guitar plays a final, simple melodic figure that fades out.)\n(Vocal-Perf: Fades to a near-whisper; Final line delivered with a sense of gentle finality.)\n(Mix: All effects and wide layers fade, leaving only the dry, central vocal and guitar.)\nMaybe we get married one day, but who knows?\nThink I'll take that thought to the grave, but who knows?\nI know that I'll love you always\nYeah, girl, you, and I like that",
