Music can be a wonderful thing, but it also has a dark side. The Huffington Post has this list of dangerous music–sounds that allegedly to violence, murder, suicide and other horrible things.
Yes, it includes things like black metal, but have you ever heard of “the glass armonica of depression?” Start with that and then move on to the rest of the list. But be very, very careful. This music could be hazardous to your health and the well-being to those around you.
