If you're like me and don't like cddb, or just have a CD that is listed in freedb and not cddb, just add this line to your /etc/hosts file to use freedb with itunes (and everything else that tries to use cddb.cddb.org):
64.71.163.204 cddb.cddb.orgYou'll have to edit the file as root or sudo edit it. Every application that tries to access cddb.cddb.org will instead load the above IP number, which is actually freedb.org.
