People like to listen to music that plays in harmony with their soul. A person without fire in their belly is not interesting to me. It is somewhat different from what the majority of people like. I often listen to bands like KORN or Metallica who seem way too heavy. I do like them though.
Music determines clothes, maybe the way people speak.
A person's character is different from their inner emotions. People sometimes totally surprise you and most people like a huge variety of music. I don't listen to rap because it's just all language and violence incorporated. That reflects me as a person. On the flip side I like stuff such as Phish and Pink Floyd, which are sometimes known as 'stoner' music.
