Yes it is important to realise that the "name/title" of a CD is not actually stored on it so the CD reader can not use the CD itself to get Artist, album, track name information. The CD reader analyses the CD content and then goes to a database and compares this information in the database to recall a number of close match options for the name of the CD. Once selected it uses this information to populate the Artist/Album/Track names as it rips.
You can load an (unfortunately old and now frozen) CD database onto the B2 so that it can look at this when not connected to the internet but for best results a live internet connection is needed so that the Brennan can look things up in external, internet based databases.
Alternatively you can enter this information by hand from the front controls on the unit or from the Web UI (assuming you have a WiFi Router (with or without an internet connection).
