I was listening to a radio program a couple years back and the host, "Mojo in the Morning", was reporting on a study some college students had done regarding animals reaction to music. I can't remember for the life of me what band which animals liked/hated most, but I do remember that the dog group only reacted to Metallica and they hated it. They played other metal music to see if it was the genre, but no, it was only Metallica that made them go bonkers. I don't blame them. I also dislike Metallica.
