I had bought the recent J&M digital player and decided to order this software. I noticed a few glitches with it, but basically it makes it easier to load a flash drive with the songs you want. The nice thing is you can save your list should you want to rebuilt your flash drive, or make a duplicate. Example, you wan reload your list that may have been in original CD order and scramble the list and install it again. So it has it's benefits.
