Thanks for posting. Hmm, I believe you're referring to folders rather then maps? Is so, here's what I do - I create playlists for different "themes" or "genres" or "moods". This way, you'll be able to easily find your tracks again and don't have them all in one long list.
Just in case you haven't used playlists before, please see this article on our help center to learn how to set one up.
Hope this helps :-)
