I use Windows Media Player myself, and found a plugin that reads the CD-Text information for unrecognized discs.
This meant that I was able to get all of the information I needed, and just touch it up as I go (separating episode scores into "Albums", applying art, populating Composer and Conductor tags etc.).
I think there may be a script out there or something to allow iTunes to read the CD-Text data. That way, CDDB is not needed for this release.
