for me it's been stable, I still wish they would add an easier way to update your collection from the main RB lists to the usb. I add and move tracks a lot and I always have to delete all playlists and export again (which doesnt take too long because the tracks are on the drive in most cases), Just wish they would do an "update collection" to make the changes on the usb drive that I made locally
other then that and some more suggestions, It's been great for me
