There's a BBC Radio podcast I love called, "Soul Music," which is "a series about pieces of music with a powerful emotional impact." Been going since the late-aughts. It takes specific songs - a truly wide variety - and talks to all sorts of people, some famous, some regular Joes, maybe gives some history, all about the effect the song has had on them.
I started listening to the one about "Gracias a la Vida," a song by Chilean Violet Parra, made well-known by Mercedes Sosa. The first person it talks to is an Australian actress who states that if you asked her what she is, she would say, "A walker," and talks about her life of walking, starting with her hours through the Australian bush as a child. I thought, "I've got to send this to my forum peeps"!
And, then, guess where she decides to go walk? She tells a remarkable Camino tale of discovering this song.
It's 30 minutes long:
