Does aggressive music change your attitude?

It's difficult to conduct a psychological test to determine the affects of music on a group of subjects, due to differences in personality, age, background, etc. Those factors may determine how sensitive a person is to the lyrics of the music they listen to, but generally people don't pay attention to the lyrics of the music they listen to. People who are already aggressive are stimulated by aggression in the media, but people who are nonaggressive have not been proven to have a difference in behavior as a result of listening to aggressive music, watching television, or playing violent Video Games like Grand Theft Auto. However, aggressive music has an affect on your mood--it can raise your adrenaline and make you angry or increase aggressiveness and competitiveness. But whether or not you act on it is determined by you already are as a person.
