iCDc is an Audio CD cataloguing tool for Mac OS X. With iCDc you can view and edit the title and artist information about Audio CDs that is stored by iTunes in the CD Info.cidb file in the Preferences folder.
iCDc can automatically download Audio CD information from a database on the Internet called freedb.org. You can choose to download information about one CD at a time or queue several CDs and download them all at once. You can upload information for CDs that do not exist in the freedb database and also update existing entries.
