I 'spose I'm old. Have been hearing music well before WiFi existed, before many EMF's in the environment. Before there was metal in my teeth and after the metal was removed. I think of it as nature's music, even though sometimes it sounds like heavy metal. Other times it is classical. I feel fortunate to "receive" different channels. My favorite is the native drums, flutes & chants or the cosmic Pink Floyd style derivative. I no longer question it, rather enjoy it.
