  "lyrics": "[intro]\n(Chords: C#maj7 - A#m7 - F#maj7 - F#maj7)\n(Inst: Warm electric piano playing sparse, gentle chords with a soft, felt-like timbre. Room reverb creates space.)\n(Melody-Contour: Static pitch establishing key.)\n(Mix: Centered, intimate focus.)\n\n[verse]\n(Chords: C#maj7 - A#m7 - F#maj7 - G#7)\n(Vocal-Perf: Conversational, soft chest voice, very close to the mic, capturing breath sounds.)\n(Inst: Electric piano continues, a simple round sub-bass enters on root notes.)\n(Melody-Rhythm: Flowing and speech-like, following natural cadence.)\n(Mix: Vocal is dry and upfront, piano is wider.)\nFound a receipt inside my winter coat\nfrom that diner off Fifth where we split the French toast\nYou always ordered decaf, said caffeine made you shake\nI never told you that I switched your cup by mistake\nThere's a photo booth strip tucked behind the mirror frame\nfour frames, four expressions, and we're laughing just the same\nI should throw it out, I set a date and then I don't\nSome things stay past their expiry and I can't make them go\n(Transition: A subtle, clean electric guitar swell fades in at the end of the section.)\n\n[pre-chorus]\n(Chords: F#maj7 - G#7 - C#maj7 - A#m7)\n(Vocal-Perf: Slight increase in volume and emotional intensity, building tension.)\n(Inst: Minimalist drums enter with a soft kick and a light, reverby snare on beat 3. Shimmering electric guitar arpeggios are introduced, panned wide.)\n(Melody-Harmony: Ascending line creates anticipation.)\n(Mix: Stereo field widens with the addition of guitar.)\nI rehearsed a version of okay\nthat fits inside my throat most days\nbut the automatic doors at our old store\nstill open like they're waiting, like before\nAnd I walk through anyway\n(Transition: A very brief pause before the chorus hits.)\n\n[chorus]\n(Chords: D#m7 - G#7 - C#maj7 - A#m7)\n(Vocal-Perf: More open and sustained, with subtle breathy falsetto on higher notes. A quiet harmony layer is added.)\n(Inst: The full arrangement is present. Bass is more melodic, guitar plays atmospheric swells and arpeggios.)\n(Melody-Contour: Higher register, anthemic arch shape.)\n(Mix: Widest point of the song, vocals sit in a bed of reverb.)\nEverything has an expiry date\nexcept the way I hear your name\nin the hum of the refrigerator running late\nin the pause before I fall asleep\nI know the shelf is bare, I know\nbut I keep reaching anyway\nEverything has an expiry date\neverything except today\n(Transition: Guitar holds a sustained chord that fades as the arrangement thins out for the next verse.)\n\n[verse]\n(Chords: C#maj7 - A#m7 - F#maj7 - G#7)\n(Vocal-Perf: Returns to a more intimate, conversational delivery, but with slightly more weight than the first verse.)\n(Inst: Drums and guitar remain but are played much more sparsely, creating dynamic contrast with the chorus.)\n(Melody-Dev: Subtle variation on the first verse melody.)\n(Mix: Pulls back to a narrower field, refocusing on the lead vocal.)\nYour jacket's in a box I taped but never labeled\nthere's a logic to that I'm not fully able\nto explain — I just know that naming it makes it real\nand real means gone and gone means I have to feel\nSo the box sits by the door like a question I've postponed\n(Transition: Drums and guitar build slightly in the last bar.)\n\n[pre-chorus]\n(Chords: F#maj7 - G#7 - C#maj7 - A#m7)\n(Vocal-Perf: Voice cracks with emotion, delivery becomes more desperate and pleading.)\n(Inst: Arrangement builds similarly to the first pre-chorus, driving towards the final chorus.)\n(Melody-Rhythm: Slightly more syncopated and rhythmically urgent.)\n(Mix: Energy and width build to match the first pre-chorus.)\nI'm not holding on, I'm just not throwing out\nthere's a difference I swear, even when I doubt\nBut the timestamp on the last thing that you sent\nreads eleven months ago and I still know what it meant\n(Transition: Drum fill is a simple two hits on the snare leading into the chorus.)\n\n[chorus]\n(Chords: D#m7 - G#7 - C#maj7 - A#m7)\n(Vocal-Perf: Most powerful delivery, with more prominent harmonies and emotional ad-libs in the background.)\n(Inst: All elements at full intensity. A subtle shaker or tambourine is added for texture.)\n(Melody-Contour: The melodic peak of the song.)\n(Mix: Lush, wide, and saturated with reverb. The emotional climax.)\nEverything has an expiry date\nexcept the way I hear your name\nin the hum of the refrigerator running late\nin the pause before I fall asleep\nI know the shelf is bare, I know\nbut I keep reaching anyway\nEverything has an expiry date\neverything except today\n(Transition: Music abruptly cuts on the final beat, leaving a long reverb tail.)\n\n[outro]\n(Chords: D#m7 - G#7 - C#maj7)\n(Vocal-Perf: Fades to a whisper, fragmented and melancholic.)\n(Inst: Instruments fade out gradually, leaving only the electric piano playing the final chords.)\n(Mix: Slowly narrows and fades to silence, emphasizing the feeling of emptiness.)\n(Sound-Design: The sound of distant city ambiance or a train passing could be subtly mixed in.)\nDecaf, four frames, a taped-up box\nand the door still opens",
