  "lyrics": "[intro]\n(Chords: Fmaj7 - C/E - Dm7 - C - Bbmaj7 - Am7 - Gm7 - C7sus4 - C7)\n(Inst: Lush strings, gentle Rhodes piano, sparse bass and drums. Female backing vocals enter with a soft, layered harmony.)\n(Vocal-Perf: Breathy, gentle, floating head voice.)\nOh… somewhere close\nstill so close, I know\n\n[verse]\n(Chords: Fmaj7 - Edim7 - A7 - Dm7 - Gm7 - Am7 - Bbmaj7 - C7)\n(Inst: Full rhythm section enters. Bass plays a melodic, walking line. Rhodes plays syncopated chords. Clean electric guitar plays muted chucks on the off-beats.)\n(Vocal-Perf: Conversational, chest voice, clear and upfront.)\n(Mix: Vocals centered, rhythm section providing a solid foundation, wide stereo field.)\nYour sweater's still folded on the second shelf\nI kept the voicemail, couldn't bring myself\nTo clear the space you used to fill with noise\nThe kettle hissing — that familiar voice\n\n[pre-chorus]\n(Chords: Gm7 - C7 - Am7 - Dm7 - Gm7 - C7 - Fmaj7 - F7)\n(Inst: Strings and brass swell, building tension. Drums become more active with subtle fills.)\n(Vocal-Perf: Intensity builds, rising in pitch and volume, leading into the chorus.)\n(Transition: Drum fill with a cymbal crash.)\nAnd Tuesday felt like holding glass\nSo careful not to make it last\nI dialed your number, pressed delete\nStood in the hallway — incomplete\n\n[chorus]\n(Chords: Bbmaj7 - Am7 - Dm7 - Gm7 - C7 - Fmaj7 - F7)\n(Inst: Brass section enters with powerful, syncopated stabs. Strings play soaring counter-melodies. The full arrangement is active and dynamic.)\n(Vocal-Perf: Powerful, emotive, full-throated belt. Backing vocals echo key phrases.)\n(Melody-Dev: The main hook is highly memorable and rhythmically punchy.)\nI let you slow dissolve — like sugar in the rain\nEvery part of you still lingers in the grain\nOf this apartment, of this city, of my skin\nI let you slow dissolve — and I'd do it all again\n\n[verse]\n(Chords: Fmaj7 - Edim7 - A7 - Dm7 - Gm7 - Am7 - Bbmaj7 - C7)\n(Inst: Arrangement pulls back slightly to match Verse 1's energy, but with subtle string pads remaining.)\n(Vocal-Perf: Returns to a more narrative, restrained delivery, with a touch of melancholy.)\n(Sound-Design: Subtle saxophone fills in the gaps between vocal phrases.)\nYour handwriting on the grocery list —\nstill taped beside the fridge, I can't resist\nReading it like scripture, cheap and worn\nSome habits outlast everything they're born from\n\n[chorus]\n(Chords: Bbmaj7 - Am7 - Dm7 - Gm7 - C7 - Fmaj7 - F7)\n(Inst: Full dynamic energy returns. Brass and strings are prominent. Alto sax begins to ad-lib more freely in the background.)\n(Vocal-Perf: Maximum emotional intensity, with ad-libs and slight melodic variations.)\n(Mix: Dense, layered, all elements driving the energy forward.)\nI let you slow dissolve — like sugar in the rain\nEvery part of you still lingers in the grain\nOf this apartment, of this city, of my skin\nI let you slow dissolve — and I'd do it all again\n\n[outro]\n(Chords: Bbmaj7 - Am7 - Gm7 - C7 - Fmaj7)\n(Inst: Music begins to fade out. Alto sax takes over with a lyrical, improvised solo. Rhythm section gradually simplifies.)\n(Vocal-Perf: Lead vocal repeats the main hook with a fading, wistful quality.)\n(Structure: Fade out.)\nSlow dissolve… slow dissolve\nStill wearing you like something I can't solve\nOh… slow dissolve",
