  "lyrics": "[intro]\n(Chords: C#m - A - E - B)\n(Groove: slow 4/4 piano ballad feel, sparse)\n(Arrangement: solo grand piano, clean tone, light reverb)\n\n[verse]\n(Chords: C#m - A - E - B)\n(Vocal-Perf: emotive and clean high tenor, intimate delivery, gentle build)\n(Arrangement: piano continues, simple sub-bass enters, dry vocal forward in the mix)\nYour jacket's still hung by the door\nLike you just stepped out for a while\nI haven't moved it, don't know what for\nMaybe I'm still holding on to that lie\nThe coffee cups have gone cold on the shelf\nTwo of them, side by side — only one was filled\n\n[pre-chorus]\n(Chords: A - B - C#m)\n(Vocal-Perf: building intensity, sustained notes)\n(Arrangement: subtle string pads swell underneath, creating tension)\nAnd the silence in this apartment\nSounds exactly like your name\n\n[chorus]\n(Chords: C#m - A - E - B)\n(Groove: simple backbeat drum groove enters, kick on 1 and 3, snare on 2 and 4, heavy reverb)\n(Lead-Melody: soaring octave leap on key phrase, highly memorable hook)\n(Vocal-Perf: full-power belting, layered vocal harmonies)\n(Arrangement: full dynamic peak, wide stereo strings, impactful piano chords)\nThese paper walls have heard it all\nEvery word I never said before you left\nI press my back against the cold\nAnd ask the dark if love was worth the cost\nOf all these paper walls\n\n[verse]\n(Chords: C#m - A - E - B)\n(Vocal-Perf: slightly more confident delivery than first verse, narrative continues)\n(Arrangement: groove continues from chorus but slightly pulled back, piano still dominant)\nI drove past the diner on Fifth last night\nOur booth was taken by two strangers laughing loud\nI sat in the parking lot, killed the lights\nWondered how it feels to be that free, that proud\nTo not be the one still stitching up the seams\nOf every room that ever held the two of us\n\n[bridge]\n(Chords: A - E - B - C#m)\n(Groove: drums drop out)\n(Vocal-Perf: airy falsetto oohs, calling out with heavy echo)\n(Arrangement: atmospheric, piano plays arpeggios, strings are more prominent, builds back to final chorus)\nI keep replaying the last thing you said\nHow your voice cracked on goodbye like it wanted to stay\nAnd I stood at the threshold, frozen instead\nWatching the tail lights dissolve in the grey\n\n[chorus]\n(Chords: C#m - A - E - B)\n(Groove: full drum groove returns with more energy, cymbal crashes)\n(Lead-Melody: soaring octave leap, ad-libs added)\n(Vocal-Perf: maximum emotional power, passionate ad-libs and runs over the top)\n(Arrangement: biggest dynamic point, all elements in, wide and epic mix)\n'Cause these paper walls have heard it all\nEvery truth I swallowed with a smile\nI'm learning how to stand up straight and tall\nBut the echo of us lingers in the hall\nThrough these paper walls\n\n[outro]\n(Chords: C#m - A - E)\n(Groove: beat fades out)\n(Vocal-Perf: softer, more vulnerable, almost a whisper)\n(Arrangement: instrumentation fades, leaving just piano and a final vocal phrase, long reverb tail)\nYour jacket's still hung by the door\nBut I think I'll move it now",
