To delete data in bulk, you can select several items from a list and then right-click “Delete”.
For Audio Manager:
- Delete all Albums which will delete the associated Tracks
- Then delete the associated Contributors (Artists, Record Labels)
For Works Manager:
- Delete all Works
- Then delete the associated Contributors (Songwriters, Music Publishers)
Optionally, if you do not want to use default Tags and Tag Categories in the future, you can also delete them.
You can delete any data for any list by doing this.
