Ok, I think I see what's going on.
Adding folders seems to work fine, either by the context menu or by dragging the folder into Playing Now. It does add the files within the folder by filename by default.
However, adding a selection of files, either through the context menu or drag & drop to Playing Now, has incorrect behavior. To reproduce:
- Select a set of files
- Drag and drop those into Playing Now by clicking and holding onto the first file in that list.
- OR, right click the first file and use the context menu to add to Playing Now
Result: Proper ordering of the files
Now,
- Drag and drop those same files, except clicking and holding onto any of the other files in the list
- OR, use the context menu
Result: Incorrect ordering based off which filed you selected
I have never once seen an application change its behavior depending on which specific file was clicked on when dragging and dropping a list of files or using a context menu. This has to be a bug!!
