I don't know but i have version 42, and I don't have to copy and paste the soups to update them. It places my new music in the correct soups automatically.

When I had version 35, I would have to copy and paste the soups and that worked fine, but when I'd use Rio Emplode after doing that it would totally [censored] everthing up.

What I do now is load my new music onto the player with Emplode (out of ease of use), and then after that I sync with JEmpeg because it automatically places all that new music in the right soups.
