How do different types of music such as heavy metal rap or country affect a persons behavior?
I would think that most “suitable” music is chosen simply because it has always been chosen. People who have certain behaviour might listen to certain music because that is what they believe is suitable for that activity, e.g. most people play play pop or rap/hiphop at a disco because that is what is always played at a disco. Music does not change how you behave, but it can amplify behaviour simply because that is what you think when you listen, and you listen because that is what you are thinking/feeling.
