It's a misconception that there is a single type of music that "educated people" listen to. Music taste is incredibly diverse and influenced by various factors like personal experiences, cultural background, and individual preferences. While some studies suggest a correlation between higher intelligence and a preference for instrumental music, this doesn't define the musical tastes of all educated individuals.
For instance, a person with a PhD in literature might be a fan of heavy metal, while another with a law degree might prefer classical music. Ultimately, the music someone listens to is a reflection of their personal interests and experiences, regardless of their educational background.
Instead of trying to categorize music based on education level, it's more meaningful to appreciate the diversity and richness of musical genres and understand how they connect with individuals on a personal level.
