I can say that nothing quite centers me like listening to Django Reinhardt and Stephane Grapelli.
I listen to every type of music and incorporate most types to every aspect of my life; however, I lend an ear to that Jazz when no one is around. When I am by myself and need to hit the reset button. It is as technically good as it is soothing. It represents a balance and brings me back to normal level. Everyone should have such a tool.
