Finding out the music that someone else likes seems to give you a lot of information about them quickly. A study by Peter Rentfrow, and Sam Gosling published in Psychological Science in 2006 found that college students getting to know each other over the internet are more likely to ask about music preferences than about all other categories of conversation topics combined. This research also found that knowing someone’s music preferences allowed students to do a reasonable job of predicting some of the new person’s personality characteristics and values. Personality characteristics are the basic dimensions of behavior along which people differ. Values are beliefs and goals that influence how people approach the world.
In the end, of course, we can’t know from this research whether music influences values or values influence the music people like (or both). That is, people may generally spend time with others who share their values.In these social settings, music is often shared, and the music you hear affects what music you like.So, sharing values could cause music preference.
