Using tag files to build music directory

I have an old iPod's iTunes directory, which I can bring up with my OS X version of MP3 tag. The program creates a long list of mp3s (I have a lot of files). What is confounding me is trying to create a directory structure of music that I can export to a Brennan B2 device. The Brennan requires artist/album/track structure

Thanks all


I assume that this is a question for the Mac section.
