Export iTunes playlists with folder structure intact
The link below has the answer. With no need for downloading any software or scripts / patches.

You need to use Terminal, but there's a simple to follow video, and minimal steps on the page:

With selected playlist, choose File > Library > Export Playlist and choose m3u8 format
Open a shell and run tr '\r' '\n' &lt; input_m3u | cpio -pd  destination_directory &gt; m3u_file where input_m3u is your playlist file, destination_directory the root folder to put the directory tree in and m3u_file is a new playlist file for the new tree (?). You can leave out &gt; m3u_file, you will see a bunch of messages like ´Cannot lstat ...`  which you can ignore.


I've just done exactly the same thing as you want to do, so I can say from personal experience that it works. Copies a playlist to a new location whilst keeping the iTunes folder structure exactly the same (so by Artist, Album or compilation, etc) depending on how you have you iTunes folder set up. If you set the new location as a SD disk (or external drive) it will copy it straight there.
