3.5. Library Groups
Library groups are local organizational labels. Use the group selector to show All Groups, Ungrouped, one local group, or a group inside an imported shared collection.
Choose Library → Manage Groups to create, rename, reorder, or delete local groups. Deleting a group keeps its tracks and returns them to Ungrouped. Select one or more local tracks and use Move to Group to change their membership.
The Library group selector only changes what is visible in the Library. The group selector in Mix independently chooses which groups can supply tracks during generation, and that selection is saved with the Mix.
