Headphones for Labor and Delivery?

Recently, several people have asked me about the possibility of have some of my pre-programmed surgical headphones programmed for labor and deliver. I think it's a great idea because it could keep the labor progressing. The phenomenon of musical entrainment is powerful and the body responds to the tempo and mood of any piece of music! I've always that Ravel's "Bolero" would be a good piece for labor and delivery. What do you think?
