Remember Mary Poppins? That nanny chick that took care of kids in some a semi-cartoon world. You need to check out this death metal version of "Supercalifragilisticexpialidocious" but get a spoonful of sugar, you're going to need it to help this go down.
One of the best things about kids is that they have no pre-conceived notions about certain things like music. They know nothing about the sub-culture of each genre and the politics within it. Their minds fall into the realm of "I may not know art, but I know what I like." In this case, art is brutal death metal.
