I'm not sure when the new music was introduced. At least a year ago. In my state, gymnasts have the choice of the old or new music. Most use the old music.
My husband says that he used to think Pickle's floor music was really irritating until he heard the new music. At our gym, we use old. If I had a choice, I'd stick with old. But, if I were a coach I'd tell everyone which one they had to use.
