Music

Why is there music everywhere? Wherever you go. Radio, people humming, singing, whistling, playing their iPods. Where does all the music come from? Just wondering if anyone has an idea. Dogs don't have music and it doesn't bother them. Music 'sets the mood' for human activity. When the music doesn't match our mood, we change the channel until we find something that does. Why is it that sometimes I love Hank Williams and sometimes his music drives me straight over the edge? I should see if there are studies that have been done.
