How does music reflect a persons personality

In friend groups people may have similar behaviors but none of them share the same music taste. Why is that? The article, The Psychology of music preferences it makes this clear. Tomas Chamorro-Premuzic Ph.D explains to us why this happens.  There are  two radically opposed theories on the psychology of music that explains why people like the music they like.

The first theory is that, "One is that song preferences are completely random (this includes the idea that arbitrary subjective experiences can make you like or dislike the same song)."(The psychology of music) This means that life experiences can make certain music types for people more meaningful causing them to enjoy certain types more than others. For example when my friend went through the loss of a family member she began to listen to sad music and that music became important to her and acted like a coping mechanism. 

The second theory is that, "The other, that our musical choices reflect important aspects of our personality." (The psychology of music) This means that music taste derives from the frontal lobe of all people. The frontal lobe creates the personality of all individuals. For instance if someone was a very lively and happy person they would most likely enjoy upbeat music such as pop due to their personality. My cousin suffers from depression and that makes her have a dull and glum personality. She enjoys sad quiet music rather that upbeat pop music because it goes along with her personality. 

Music taste can be determined by the two factors mentioned above. Depending on the person their music taste may reflect their personality completely or may have no effects at all. Each person is different and it is hard to pin point a specific reasoning.
