When we listen to music, all the areas of the brain light up, or are stimulated. Music is one of the only stimuli that affects all areas of the brain.

When we just listen to music, it starts at the cochlear nuclei , then the brain stem ,

then the cerebellum, and then it reaches the auditory cortices on both sides of the brain 

Below are two clips from the same 2-hour movie about how music affects us in different ways. The first clip below shows the path the music follows as it enters the brain. The second clip is about how the music affects the brain.
