What effect does music have on emotions?

To answer this overall research question, I will try to find out:

1. What is the relationship between music and psychology?



2. Why are different people attracted to different types of music?



3. Why do stores play certain music?



4. Can a type of music be created to help keep debates calm?

This is what I already know about this topic and want to find out: I know that different people like different music, like hip-hop, classic rock, alternative, etc., but why is that? Is it because they are raised differently from each other?

How does music affect emotions? I know that music artist like Michael Franti and Jack Johnson think that music is a source of happiness.

Music for me is a way to clear my head, be more efficent, or sometimes just the opposite: it helps me procrastinate, too. Musioc really just works for me, I use it to my advantage.
