Personality trait (introversion vs extroversion) and musical preferences?
As an example:
I am very introverted (as in, if people had not approached me for social relations, I would be friendless and not bothered by it). I enjoy classical music. My favourite musical period is the Baroque period, because I enjoy following the structure of the music. I also enjoy exploring the 20th/21st century classical repertoire, as I like to hear new combinations of sounds and new ways of structuring musical pieces. I also like to hear how modern music has grown out of older music.
So far, the trend seems to be toward introversion and a liking for classical music, with reasons revolving around wanting to listen to something with substance.
PEOPLE WHO'VE CONTRIBUTED: if you have anyone who doesn't prefer classical music in your contacts, bug them to answer this. I'm looking for a wide spectrum of music-listening preferences.
