If i reinstall itunes after i reset my computer to factory settings will my music be lost?
Download it again
You can either attach the iPod to a computer with iTunes installed to restore the device to factory settings. Alternatively, look for 'Settings' on the iPod screen, then find the 'Reset' menu in the 'General' menu on the device. When clicked, you will see 'Erase All Content and Settings' at the top. This will reset the iPod default settings.
