I hope your music is as pleasant as mine. I decided to welcome it as nice background music piped in from my own brain. It doesn’t distract me from attention to whatever I’m doing, including going to sleep. I haven’t mentioned it to family members or friends because it seems so odd. I am tempted to compare this phenomena with the spoken voices produced by the brains of schizophrenic folks. As a matter of fact, there must be similarities in that our brains, like theirs perhaps, are involuntarily producing actual music though not actual spoken words. The brain process certainly might be similar. I wish I knew why and my brain choses the music, all familiar songs. Sometimes for days the song remains the same such as the multiple repeats of “Amazing Grace.” Sometimes I say to myself, amused, “Why THIS particular song?” … or why these particular songs, not others, come apparently to entertain me though I had not been thinking of any of these songs. I cannot change whatever song is “playing” and I cannot end it, and the songs are not songs I’ve been thinking about or wishing to hear. None have been songs I dislike. I guess I could thank my brain for that, but isn’t my brain ME?… I am the one responsible for the songs, no one else. It’s a puzzlement. A mystery .
