Property Get/Let IsntInDB As Boolean
Returns True if the track is not stored in the Library. Defaults to False. Returns False when
- Track is in the Library (SongID > 0)
- When MM does not know anything yet (SongID = -1)
In order for this property to be updated, MM needs to query the database. If the user sets this property to False, MM will not do a query to the database. This is done by device plug-ins extensively in order to avoid expensive database queries.
