The study is just placing people into groups based on hierarchy. It sounds like it is based more off of stereotypes than actual statistics. I do not think that it is a good representation of the population as a whole. Musical tastes vary from person to person. It is more about culture and personal ideologies than education. I know high school educated people who listen to a variety of different music from rock to jazz. But, I also know high school dropouts and other cretins who listen to the likes of ICP, Korn, and Marilyn Manson.
In other words, it depends entirely on the individual. I think that the study is intentionally trying to base everything on education and traditional stereotypes. I do not even listen to Wasp myself, nor do I know anyone who listens to them. I do not even consider myself a metal head. I listen to Opeth, David Bowie, and so on because I do not believe in limiting myself to one musical genre. I really do not try to fit myself into a particular group either. What is the point? Every genre of music should be enjoyed.
