[vorbis-dev] what about storing free-cddb-id in comments inside .ogg ?

And what if that CD has more than one FREEDBID?
The FREEDB spec allows for any number of inexact matches based on one CD.
http://www.freedb.org/sections.php?op=viewarticle&artid=6
and
http://www.freedb.org/software/freedb.howto1.06.zip
scroll down to line 192 where it reads:
"Different pressings of a particular CD title may contain differences in
timings that can cause the computed disc ID to be different."

My guess would be that if the multiple FREEDB ids are known; they should be
separated by comma's just like the FREEDB database returns in the data
payload given by a successful search:

Reference line 881 in the same file:
"DISCID: The data following this keyword should be a comma-separated list of
8-byte disc IDs."
and line 951:
"DISCID=270b8617,5f430c17,[ ... ],4c72be17"
