Audiobooks in both bookbrainz and musicbrainz

[indy133]

There recently has been a small discussion about this topic here:

Does it make sense to create separate editions for audiobook CDs distributed with the printed book?

I have several printed books that come with a CD of someone reading the text and I was wondering if such CDs should be added to the database as a separate edition. I generally think they should, but given the fact these CDs weren’t sold separately, I don’t know if it’s correct to do that?

My position is clear but there has been no final decision yet
