Personality traits and musical preferences

A recent study suggests that the kind of music we prefer may have less to do with taste (or lack thereof) and more to do with our personalities. For example, being a fan of opera could indicate that you are a gentle soul, with high self esteem and a creative bent. Other genres have other implications, as Professor North has researched.
