Query: Outstanding product for Napster to Go!

It is like having your own digital jukebox to hook up to speakers and play all the music you want for a small fee. The only item that I enjoy as much as my Rio is my XBOX 360. PS.. make sure you are in the proper mode before flashing the firmware for playforsure. If not it will hang during the "acquiring license" phase.
