In terms of my little framework, you're exercising the pattern engine by making predictions and immediately having them validated. Notice how some people will try to sing along to a song even when they've never heard it before, and how the best pop songs make this very easy to do.
This fits in with an observation (internally, of myself, so probably not scientifically valid) that when I dance to music, it starts to feel like I'm creating the music with my movements. Of course I'm just moving to what I know the music is going to do, but it feels good when you feel like you're doing the opposite.
