How does non-tagged music get named (either because FreedDB cannot recognise the CD or the user does not have a broadband connection)?

Before a CD is ripped to the hard drive you are able to change the details that have been discovered by CD identification e.g. to correct mistakes. If the CD could not be identified then the details default to Unknown and you can enter any details you wish for Genre, Artist and Album. When the CD is ripped, the tracks will automatically be named Track 1, Track 2 etc. but these individual track names can be changed later if necessary using the Organise menus.
