  "lyrics": "[intro]\n(Chords: Cmaj7 - Fmaj7)\n(Inst: Lo-fi piano playing gentle, spacious arpeggios. Faint atmospheric synth pad enters.)\n(Mix: Narrow, intimate space.)\n(Sound-Design: Subtle vinyl crackle.)\n(Transition: Vocal breath enters just before the beat drops.)\n\n[verse]\n(Chords: Cmaj7 - Fmaj7 - Cmaj7 - Fmaj7)\n(Vocal-Perf: Soft, breathy chest voice, conversational.)\n(Inst: Piano continues. A deep, simple 808 sub-bass enters with sparse 16th-note hi-hats.)\n(Mix: Vocals centered and upfront, with a noticeable room reverb tail.)\nLeft your jacket on my chair again\nThree weeks and I haven't moved a thing\nThe voicemail that I played until the battery died\nStill got your coffee mug beside mine\n(I keep the screen on low)\n\n[pre-chorus]\n(Chords: Am - G)\n(Vocal-Perf: Intensity starts to build, still in chest voice but with more power.)\n(Inst: A full half-time drum beat enters with a heavily reverbed snare. Lush, wide synth pads swell.)\n(Mix: Begins to expand into a wider stereo field.)\n(Transition: A subtle synth riser swells quietly.)\nEvery contact in my phone still has your name\nI keep the read receipts on like you might explain\nWhat broke without a sound\nWhat left without a trace\nTell me\nTell me\n\n[chorus]\n(Chords: C - F - Am - G)\n(Vocal-Perf: Jumps to a strained, powerful falsetto. High emotional intensity. The song's highlight.)\n(Inst: Full instrumentation, piano plays block chords. Synths are at their peak.)\n(Mix: Fully wide, cavernous, and powerful. Vocals are layered and drenched in reverb.)\n(Transition: A beat of silence before the chorus hits.)\nI'm still sending love into the static\nWaiting on a signal that went dark\nAll this noise I made won't reach you\nAnd I know\nOh I know\n\n[verse]\n(Chords: Cmaj7 - Fmaj7)\n(Vocal-Perf: Returns to the intimate, low-energy chest voice, creating dynamic contrast.)\n(Inst: Beat strips back down to sub-bass and hi-hats. Piano returns to arpeggios.)\n(Mix: The space collapses back to the intimate feel of the first verse.)\n(Transition: A reversed cymbal swell leads into the verse, instruments drop out leaving a pad.)\nFound a note you wrote inside a book\nThe ink so faint I had to look and look\nYour handwriting still bends the way it always did\nFunny how the smallest things don't quit\nHow they hold\n\n[pre-chorus]\n(Chords: Am - G)\n(Vocal-Perf: Builds again, with a slight rasp or strain showing.)\n(Inst: Full beat and pads return.)\n(Mix: Widens out again in preparation for the final chorus.)\n(Transition: Synth riser swells again, more prominently this time.)\nI pulled our last location up on maps at two\n(yeah yeah yeah)\nThe pin just sits there frozen, nothing I can do\nLike a door left on the latch\nFor someone who won't come\nTell me\nTell me\n\n[chorus]\n(Chords: C - F - Am - G)\n(Vocal-Perf: Peak emotional delivery. More ad-libs and vocal runs in falsetto.)\n(Inst: All elements are present plus a new distorted saw-wave synth lead playing a counter-melody.)\n(Mix: The biggest, widest, and most saturated part of the song.)\n(Transition: All instruments cut out except for a ringing piano chord, then everything crashes back in.)\nI'm still sending love into the static\nWaiting on a signal that went dark\nAll this noise I made won't reach you\nAnd I know\nOh I know\n\n[outro]\n(Chords: Cmaj7 - Fmaj7)\n(Vocal-Perf: Fades out with the repeated tag line, becoming breathier and quieter.)\n(Inst: Music deconstructs, leaving only the piano arpeggio and atmospheric pads, which slowly fade to silence.)\n(Mix: The long reverb tails are the last thing heard.)\n(Transition: Abrupt cut of the beat, leaving only vocals and pads hanging in reverb.)\nSignal lost\nAnd I'm still here\nIn the static\nIn the static",
