Hi Nano..
the goal (that's why it will take more time) is to have a By folders category on the main menu.. so both scenarios. You click it, you get a shortcut to your disk and from there you can start browsing like in the settings / media library watch folders.

I think the folder will solve the case of people with really no Tagged mp3 or bad tagged that are in just one big folder with subfolders by mood / other kind of organization.. not artists or albums =)
