I noticed in the MM5 database, the Medias table contains a new field for MusicBrainz Disc IDs. The MM4 Medias table does not have this field, but the last version does do MB CD lookups. I'm thinking that MM4 calculates the MB Disc ID from the TOCData field in Medias, as it does for freedb in the CDDBId field.

If that's the case, can the MusicBrainz Disc ID be accessed through the COM API? I'm not clever enough to do my own MB Disc ID calculation, which is fairly complex. I can barely calculate a freedb Disc ID from the TOC, and those are pretty easy.

Thanks.
