Here are the basic steps:
1. Import all the file types into MC that you want to show/play
2. Create a view that includes all of these file types (Set rules for file display)
3. Group that view by Filename (path), unless you tag all the items within each album. You can do this in a number of ways, depending upon the type of view you want, and how you want to navigate it. You might want a panes view that uses a File path Category, for example, or maybe various components from the [Filename (path)] field. The key here is that you need some metadata which is consistent across all the file types, and since the folder path is the only thing that is (without tagging), you need to use this or some modified version of it.
Since some of your image folders are beneath your album folder, you'll probably want an expression to modify Filename (path), to strip this folder when necessary, so that an Album shows as a single unit always.
This method assumes your folder names are structured such that the component folders can present values such as the Album, Artist, etc.
Does this seem where you want to go?
