I have my music files organiser by directory structure and I really need to categorize files by folder so they all go to the same list or get tagged the same way. Sending them to playlists or tagging them one by one seems unpractical. I tried also sort by album and grioup by artist, but some music files I want to have in the same list don't have the same album aritists.
I have for example, a large folder of music with a common theme that I want to be able to browse at once in MB.
