I'm going back too! I've had the not fun experience of having all my "to go" tracks de-authorize about a half dozen times in the past week. If the player is turned off for any significant amount of time, upon trying to play any Channels or Rhapsody to go tracks I get the message "To play this track, you must sync your device to your PC. Can't stand it. I've done a un-license, format, reinstall firmware, format, re-license all to no avail. So I'm going to have to figure out how to go back to the last firmware. Hope they fix this madness soon.
