  "lyrics": "[intro]\n(Chords: Am - G - C - F)\n(Inst: Filtered piano melody, soft synth pads swelling, distant 808 kick thumps)\n(Mix: Narrow stereo field, slowly widening)\n(Sound-Design: Subtle vinyl crackle)\n\n(Transition: Filter opens on piano, sub-bass fades in smoothly)\n[verse]\n(Chords: Am - G - C - F)\n(Inst: Reverb-heavy piano chords, deep sub-bass on root notes, steady 16th-note hi-hats enter quietly, sparse kick on 1)\n(Vocal-Perf: Intimate, breathy, close-mic'd whisper, minimal vibrato)\n(Melody-Contour: Conversational, mostly stepwise motion, low in the vocal range)\n(Melody-Rhythm: Relaxed phrasing, slightly behind the beat)\nLately\nI can't even think straight\nMemories tiashing my brain\nJust hoping\nYou're still thinking of me\nYou know what we could've been\n\n(Transition: Snare enters, synth pad layers build, subtle reverse cymbal swell)\n[pre-chorus]\n(Chords: F - C - G - Am)\n(Inst: Full beat enters, snare is more prominent, synth pads increase in volume and brightness)\n(Vocal-Perf: Volume increases slightly, more emotional intensity, still airy)\n(Melody-Contour: Ascending line, building anticipation for the chorus)\nWe turned the TV down so we could talk\nBut we spent the whole night staring at the floor\nI took my things out of the bottom drawer\nAnd just walked\n\n(Transition: Brief pause of drums for one beat before chorus hits)\n[chorus]\n(Chords: C - G - Am - F)\n(Inst: Full beat with prominent kick and snare, layered synth pads create a wide wall of sound, piano arpeggios add movement)\n(Mix: Widest stereo image, vocals have layered harmonies, sub-bass at full volume)\n(Vocal-Perf: Stronger chest voice, more projected, sustained notes with subtle vibrato, layered backing vocals)\n(Melody-Contour: Jumps up a perfect fifth for emotional impact)\n(Hook-DNA: AAB structure; a memorable 4-bar melodic phrase repeats, with the final line acting as a descending resolution)\nThat was final straw we could have had it all\nThis is our curtain call\nNow we're too far from shore we could have had it all\nThis is our curtain call\n\n(Transition: Sustained synth pad and reverb tail carries over)\n[verse]\n(Chords: Am - G - C - F)\n(Inst: Arrangement drops back down, but the hi-hats remain more present than in verse 1)\n(Vocal-Perf: Returns to intimate, breathy delivery, but with more resolve)\nLately\nI've been listening to your music god I'm only human\nAnd it seems\nLike you were searching for a muse\nI'm mad I couldn't be that for you\n\n(Transition: Drum fill with rising intensity, synth arpeggio introduced subtly)\n[pre-chorus]\n(Chords: F - C - G - Am)\n(Inst: Arrangement builds again, pads swell, snare becomes more forceful)\n(Vocal-Perf: Intensity builds, a subtle harmony added on the last line)\nWe turned the TV down so we could talk\nBut we spent the whole night staring at the floor\nI took my things out of the bottom drawer\nAnd just walked\n\n(Transition: More dramatic dropout of all instruments except a sustained pad before the final chorus)\n[chorus]\n(Chords: C - G - Am - F)\n(Inst: Most powerful section. All elements plus a new high-octave piano counter-melody. Cymbals crash on downbeats.)\n(Mix: Maximum width and volume. Vocal ad-libs panned left and right.)\n(Vocal-Perf: Most powerful delivery, full chest voice, noticeable vibrato, emotional ad-libs in background)\n(Hook-DNA: Core melody is identical, but added instrumental and vocal layers create a powerful climax)\nThat was our final straw we could have had it all\nThis is our curtain call\nNow we're too far from shore we could have had it all\nThis is our curtain call\n\n(Transition: Beat abruptly cuts, leaving only the reverb tail of the piano and vocals to decay)\n[outro]\n(Chords: Am - F - C - G)\n(Inst: Just the reverb-heavy piano playing a simple, melancholic version of the main melody, fading out)\n(Mix: Fades to silence, stereo field narrows)\n(Vocal-Perf: A single, distant, wordless vocal sigh with heavy echo)\n(Sound-Design: Vinyl crackle returns and fades, ends with the soft click of a TV turning off)",
