This function is used to access MusicBrainz to log changes between the database and your tracks and/or save the changes.
You can choose to use the import settings retained in the tracks, alternately specify a saved import settings set, or specify your own custom settings. If using the retained settings, they must be present and consistant across all tracks to be examined. The custom settings table has a context menu used to change multiple entries and to access the MusicBrainz Import Settings Manager.
The action test state will be set to true, if any attempt is made to access MusicBrainz.
Yate attempts to follow the MusicBrainz guidelines for rate limiting its requests. However, there are external causes outside of Yate's control which could cause a network response of Service Unavailable (503). You can test for 503 errors by testing the numeric value of the MusicBrainz Unavailable named variable. A non zero value implies that 503 errors occurred. When Track Matching, it is possible that the count could be greater than one.
This function is only valid in a stepwise execution context. If Import Changes is selected and the mode is Release Matching or Loose Matching, the statement will be valid in immediate mode. Otherwise the statement is only valid while batch processing. Be aware that all network accesses are rate limited. When running in immediate mode if Discogs metadata is being loaded and artwork is being loaded from multiple sources, the statement may run for a while. Note that when running in immediate mode, an open Discogs Wizard or MusicBrainz Wizard window will be closed.
