" Eclectic and unfamiliar, even unpleasant musical genres are vitamins to the musical physique. If nothing else, they help us to immediately affirm a past belief. New music can even function as vaccine—we can aesthetically inoculate ourselves against some unperceived threat to our individual musical development—a process very easily—if simplistically—defined by the way we avoid repeating something that’s already been done—a title, a lyric, a riff, an attitude or any intellectual property that rightfully belongs to someone else.
