  "lyrics": "One road goes winding by the olive tree,\nOne follows stones beside the open sea.\nThey meet beneath the same familiar roof,\nTwo ways of coming home, one simple truth.\n\nWe packed the bread and left the garden gate,\nThe afternoon was wide enough to wait.\nNo need to chase the footsteps just ahead,\nThe day could hear the softer things we said.\n\nTake the long way, take the slow,\nKeep the little tune you know.\nThough the hills may change the view,\nWhat we carry carries through.\n\nA song can wear a coat of summer blue,\nOr wrap itself in rain and still be true.\nThe voice may travel farther than the hand,\nYet bring the same small kindness when we land.\n\nWe let the passing cart go on its way,\nAnd found a shaded place where we could stay.\nThe world was not a race we had to win,\nThere was another road to wander in.\n\nTake the long way, take the slow,\nKeep the little tune you know.\nThough the hills may change the view,\nWhat we carry carries through.\n\nWhen both our roads arrive beside the door,\nWe set the bread upon the table once more.\nThe tune comes softly underneath the rain,\nAnd all the ways of home become the same.",

LIMITATIONS
No full listening review, exact lyric verification, or note-for-note transcription. Intended chords and notes are not claimed as rendered. ACE-Step1.5 code/model MIT; Qwen embedding Apache2.0. Training provenance is mixed, not exclusively public domain. No paid generation service.

WAV DELIVERY AND AUTOMATED WORD CHECK
Matching WAV is original generated PCM16 stereo48kHz, verified120.000seconds; M4A is its AAC derivative. Local Whisper base.en processed the full track but returned repeated vocalizations and incomplete/differing lyric fragments. This is a significant lyric-fidelity warning, not proof of exact wording. Full listening and exact lyric fidelity remain unverified.
