The problem is ascribing "mystery" to things that are not. The poetry in lyrics can be beautiful. It can also be asinine. It can also be generated by extreme suffering, "why does it have to be this way." Layne Stayle. It can also be generated by mysticism, but it is not in itself mystical. Humans do stuff like this all the time, they like writing and typing. Mahgister is a great example. Creating and playing music is far more complicated and we hold those who can do it special, rewarding them huge incomes and special places in history.
When I was an infant I would not sleep. My mother tried everything (except putting me in her bedroom). Finally, out of desperation, she put a table radio tuned to an all night music station in the crib with me. It worked great and the music has been playing ever since. The only mystery involved in music is why humans love it so much. It is a universal trait. Whenever you see a trait that is universal in a species somewhere back in time there was a survival benefit as almost all the critters that do not have that trait are not here anymore. I have never seen an adequate explanation for music in humans. The trait is so strong that it is present in infants.
@mahgister
You are a great example of mysticism. (IMHO)
