  "lyrics": "[intro]\n(Inst: Warm acoustic guitar, close-mic'd, audible finger slides and string resonance)\n(Vocal-Perf: Female vocal, breathy 'oohs', floating ad-libs)\n(Chords: Abmaj7 - Dbmaj7)\n(Melody-Contour: Gentle, descending melodic sighs)\n(Melody-Rhythm: Free-time, relaxed phrasing, floating over the beat)\nAhh, mmm\n\n[verse]\n(Inst: Acoustic guitar provides rhythm and harmony, bass enters with a simple root-note pulse)\n(Vocal-Perf: Female lead, soft and conversational, intimate close-mic delivery, ends phrases with airy vibrato)\n(Chords: Abmaj7 - Dbmaj7 - Cm7 - Fm7)\n(Melody-Contour: Mostly stepwise motion, small melodic range, stays low and gentle)\n(Melody-Rhythm: Syncopated phrases that weave around the guitar rhythm, leaving space)\nI spent so long\nBuilding walls up high\nThought that keeping distance\nWas how you survive\nThen you walked in quiet\nLike you already knew\nEvery room I'd hidden\nYou wandered right through\n\n[chorus]\n(Inst: Acoustic guitar strums fuller, subtle clean electric guitar enters with melodic fills)\n(Vocal-Perf: Male and Female duet in tight harmony. Female takes the higher harmony. Both voices increase in volume slightly, more sustained notes)\n(Chords: Abmaj7 - Dbmaj7 - Cm7 - Fm7)\n(Hook-DNA: Simple, repetitive motif on 'beautiful you are', descending melody, highly memorable)\n(Melody-Contour: The hook line has a memorable descending arc from the 5th down to the root)\n(Melody-Rhythm: More on-the-beat, declarative rhythm compared to the verse)\nThis is a slow burn, slow and easy\nThe way you hold me makes it hard to breathe\nAnd I don't mind, no I don't mind at all\nTake your time\nThis slow burn is all I need\nAll I need\nAll I need\n\n[verse]\n(Inst: Acoustic guitar continues, electric guitar drops out for intimacy)\n(Vocal-Perf: Male lead, warm and gentle timbre, slightly raspy texture, very relaxed phrasing)\n(Chords: Abmaj7 - Dbmaj7 - Cm7 - Fm7)\n(Melody-Contour: Similar low-range, conversational contour as the first verse)\n(Melody-Rhythm: Follows the same syncopated, weaving pattern as the female verse)\nI know the way\nYour laugh gives you away\nHow you chew your lip\nWhen you don't know what to say\nLittle things you think\nThat nobody ever sees\nI see every one\nAnd they're all part of me\n\n[chorus]\n(Inst: Acoustic guitar and electric guitar return, bass becomes slightly more active with small fills)\n(Vocal-Perf: Duet harmonies return, more confident and dynamic than the first chorus. Ad-libs added in the gaps)\n(Chords: Abmaj7 - Dbmaj7 - Cm7 - Fm7)\n(Hook-DNA: Simple, repetitive motif on 'beautiful you are', descending melody, highly memorable)\n(Mix: Same wider image as the first chorus)\nThis is a slow burn, slow and easy\nThe way you hold me makes it hard to breathe\nAnd I don't mind, no I don't mind at all\nTake your time\nThis slow burn is all I need\nAll I need\nAll I need\n\n[outro]\n(Inst: Instrumentation becomes sparser, focusing on a repetitive guitar vamp)\n(Vocal-Perf: Layered call-and-response vocals. Male lead asks the question, layered female vocals respond. Vocals become more ad-libbed and improvisational towards the end, then fade out)\n(Chords: Abmaj7 - Dbmaj7)\n(Hook-DNA: Rhythmic chant-like repetition of the main phrase, creating a hypnotic effect)\n(Mix: Vocals are treated with more reverb and delay, creating a sense of distance as the track fades)\nJust stay, stay a little longer\nStay a little longer now\nMmm\nJust stay, stay a little longer\nStay, stay\nLonger now\nJust stay, stay a little longer\nStay a little longer now\nJust stay, stay a little longer\nStay, stay\nLonger now\nJust stay, stay a little longer\nStay a little longer now\nJust stay, stay a little longer\nStay, stay\nLonger now",
