(correction please) Someone’s musical tastes say a lot about a person’s personality.
Music is the natural happiness drug. It is scientifically proven that music influences cognitive skills, learning, working memory, ways of thinking, and personal and social development – to name just a few. However, I don't think we can simply define a person's personality simply through their listening habits. Musical taste, friends, habits, etc, all are all just tiny pieces making up a person's overall personality.
That being said, we can talk in general about some examples. For instance, an introvert may find little interest in music about going out to clubs; while, a more sociable and friendly extrovert is more sociable and friendly may prefers to listen to music in clubs or pubs.
For the most part, the corrections I made weren't super necessary, more just for increasing clarity and adding better transitions.:)
