Musicbrainz ID Tag

Having cleared my database, and importing a few audio folders into AS, I notice that there would appear to be additional metadata added to my files in the form of a Musicbrainz entry.
Could someone at Audirvana please tell me whether it’s AS adding this data?
If so, is there a way in which we can turn this feature off, as I have a feeling it’s this causing the analysation of my files to fail.

And still, no answer?

Yes, Studio is adding that metadata, and no, it is not currently possible to turn off the feature, as far as I know.

If you cannot switch off the functionality, switch off AS !
