Why do we differ in our music preferences?
Some people like classical music, others like rap, others rock. There are so many other genres and sub-genres to those genres. Some people prefer heavy beats, others despise beats altogether. For some people, it's necessary that a song have lyrics. To others, the music is more important. Some people need to hear a guitar, while others enjoy simple piano melodies. And there are more subtle variations I don't know if I'm capable of recognising consciously.
So, the question is, what are the reasons that we differ in our music preferences? Do certain personality types enjoy particular types of music, or is music preference a result of virtually random brain chemistry that doesn't have much to do with personality?
