  "lyrics": "[intro]\n(Chords: Gmaj7 - Cmaj7 - Gmaj7 - Cmaj7)\n(Mix: Piano front and center, wide stereo image; Vocals have gentle reverb.)\n(Inst: Iconic arpeggiated grand piano riff establishes the song's identity.)\n(Motif-Anatomy: Arpeggiated major-seventh piano chords.)\n(Phrase-Structure: Symmetrical 4-bar piano loop.)\n(Contour-&-Range: Improvised, breathy vocal ad-libs in mid-register.)\n(Vocal-Perf: Soulful, melismatic humming and runs, setting an intimate tone.)\n\n[verse]\n(Chords: Gmaj7 - Cmaj7 - Gmaj7 - Cmaj7)\n(Transition: Full band enters gently; subtle kick and bass.)\n(Sound-Design: Soft shaker percussion adds texture.)\n(Mix: Lead vocal sits perfectly on top of the sparse arrangement, very present.)\n(Inst: Piano continues, electric bass provides a simple, warm root-note foundation.)\n(Motif-Anatomy: Conversational, rhythmically straightforward vocal melody.)\n(Phrase-Structure: Symmetrical call-and-response phrasing.)\n(Contour-&-Range: Controlled, lower-to-mid register chest voice.)\n(Vocal-Perf: Gentle, narrative delivery with soft dynamics, building anticipation.)\nWe drove three hours just to watch the tide\nYou fell asleep before we even arrived\nAnd I sat there in the dark, engine off\nListening to you breathe like that was enough\nNo grand occasion, no champagne at all\nJust the smell of rain and your old overalls\nSomething broke open quiet in my chest —\nThat ordinary Tuesday put the rest to rest\n\n[chorus]\n(Chords: Am7 - D7 - Gmaj7 - Em7 - Cmaj7 - D7 - Gmaj7)\n(Transition: Drums become more defined, ride cymbal opens up.)\n(Sound-Design: Subtle string swells enter, adding emotional weight.)\n(Mix: Wider stereo field, backing vocals panned, overall volume lift.)\n(Inst: Drums lock into a solid backbeat pocket, bass becomes more melodic.)\n(Motif-Anatomy: Soaring, anthemic vocal melody with sustained notes.)\n(Phrase-Structure: Classic 8-bar pop structure with a strong resolution.)\n(Contour-&-Range: Vocal leaps an octave into a powerful upper-register belt.)\n(Vocal-Perf: Full-throated, powerful belting; emotive vocal cracks and signature R&B runs at phrase ends.)\nGive me the kind that burns slow\nNot the flash that blinds and fades and goes\nGive me the 2 AM, the unglamorous glow\nThe kind of love that only quiet people know\nNot the highlight reel, not the overflow —\nJust your hand in mine when the cold winds blow\nThat's the only currency I'll ever need to hold\nThat warmth, that weight, that slow, slow burn of gold\n\n[verse]\n(Chords: Gmaj7 - Cmaj7 - Am7 - D7 - Gmaj7 - Em7)\n(Transition: Energy drops back down, strings fade out.)\n(Mix: Focus returns to the intimate vocal-and-piano core.)\n(Inst: Bass plays a smooth, walking line connecting the verse to the pre-chorus harmony.)\n(Motif-Anatomy: Vocal melody mirrors first verse but with more rhythmic freedom.)\n(Phrase-Structure: Extended phrasing building towards the chorus.)\n(Contour-&-Range: Stays in a comfortable mid-range, but with more dynamic swells.)\n(Vocal-Perf: Slightly more intense delivery, hints of the power shown in the chorus.)\nYou texted me a photo, blurry, out of frame\nJust a bowl of soup and a flickering flame\nSaid you thought of me when you made it tonight\nI pressed my phone against my heart and cried\nNot from sorrow — from some kind of awe\nThat love could live inside a thing so small\nA crooked smile across a thrift store table\nTurned out to be the thing that kept me stable\n\n[chorus]\n(Chords: Am7 - D7 - Gmaj7 - Em7 - Cmaj7 - D7 - Gmaj7)\n(Transition: Full band slams back in with more conviction.)\n(Sound-Design: Gospel-inspired backing vocals become more prominent.)\n(Mix: Lead vocal is layered with harmonies, creating a massive, rich sound.)\n(Inst: Ride cymbal is more pronounced, snare has more body.)\n(Motif-Anatomy: Chorus melody repeated with more vocal embellishment.)\n(Phrase-Structure: Classic 8-bar pop structure.)\n(Contour-&-Range: Consistently high-register, powerful belting.)\n(Vocal-Perf: Peak emotional delivery, extensive ad-libs and runs woven into the main melody.)\nGive me the kind that burns slow\nNot the flash that blinds and fades and goes\nGive me the 2 AM, the unglamorous glow\nThe kind of love that only quiet people know\nNot the highlight reel, not the overflow —\nJust your hand in mine when the cold winds blow\nThat's the only currency I'll ever need to hold\nThat warmth, that weight, that slow, slow burn of gold, gold, gold\n\n[bridge]\n(Chords: Am7 - D7 - Gmaj7 - Em7 - Cmaj7 - D7 - Gmaj7)\n(Transition: A continuation of the chorus energy, functioning as the song's climax.)\n(Sound-Design: Vocal ad-libs fill all the empty spaces, creating a dense wall of sound.)\n(Mix: Vocals are the dominant element, pushing the instruments slightly back.)\n(Inst: Piano plays more forceful block chords instead of arpeggios.)\n(Motif-Anatomy: Vocal improvisation and melodic fragments of the chorus.)\n(Phrase-Structure: Free-form ad-libbing over the chorus chord structure.)\n(Contour-&-Range: Explores the highest parts of the vocal range with powerful runs.)\n(Vocal-Perf: Gospel-choir style call-and-response with dense harmonies, maximum vocal power.)\nStrip away the noise, what do you find\nTwo people choosing each other every single time\nNo audience, no curtain call, no stage\nJust the same two hearts turning the same worn page\nI've tasted fast and I've tasted bright\nBut nothing ever held me through the night\nLike the slow and steady, tender, everyday —\nThat's the fire I'll keep, come what may, come what may\n\n[outro]\n(Chords: Gmaj7 - Cmaj7 - Gmaj7)\n(Transition: Sudden drop in energy, band fades out leaving only piano and vocals.)\n(Sound-Design: Final piano arpeggio resolves the song.)\n(Mix: Decrescendo, instruments fade away, leaving the final vocal very exposed and intimate.)\n(Inst: Deconstructed; only piano remains, playing the intro riff.)\n(Motif-Anatomy: Final melodic statement, a quiet reflection of the main theme.)\n(Phrase-Structure: Short, final phrases.)\n(Contour-&-Range: Vocals descend into a soft, breathy low register.)\n(Vocal-Perf: Intimate and breathy, use of vocal fry, ending on a soft, resolved note.)\nJust let it burn slow, baby\nOhh, underneath the ordinary, that's where I found it all\nRight there with you",
