Maybe... it's about someone looking back on parts of their life (or that's what I get from "why am I hovering over myself?" and "when we started walking, I was in the 1940's). In their maturity, they've learned that every person, every place and new experience is an opportunity so that they can later "rewind and play back beautiful music".
