The first thing I'd do is plug it into the usb port of your pc. Try and play the missing 10 songs on your pc.
If they play on your pc without any problem it could be they're in a file format that's not compatible.
If they don't play on your pc,wipe them from your usb stick and re load them and try again in the Juke.If still no joy</font>, then get back to us.
