Miguel, I'm with you 100% on everything you said. After all there have been times when it would drive me crazy to have to walk behind some guy listening to a baseball game on his radio or, while enjoying the sublime solitude and silence in a forest, suddenly to have it all shattered by just barely audible distant voices. Or, one interminable afternoon when this elderly woman played hiking tag, always catching up to me at my rest stops and practicing traditional Japanese folk songs in a high, nasal, screeching voice all the way.
Though it's antithetical to expect it here in Japan, I go for walks to be alone and to enjoy silence and to listen to the sounds of nature that I so rarely hear back in the city. One thing I've found since moving out here to the countryside outside Tokyo is that I've relaxed again and enjoyed waking up in the morning to the sounds of all kinds of birds, to frogs singing at night, to the sound of the wind coming off the ocean not far away.
So, yes, Miguel, I see where you are coming from.
But there are also times when I am out there and it inspires me to want to join in and complement it with my own music. On longer walks there are so many times when I suddenly break into song, I am so happy or sad, or the pain is bad enough that a song will soothe it. After all, isn't that where music comes from?
