Hi Maren,
I figured out how to shuffle multiple playlists. You need to create a tree sttucture of folders. You can have folders within folders. You can then shuffle a single folder that has several subfulders within it and each folder having several artists. In the desktop app, Click on
"File > New Playlist Folder" , Then name that folder what ever you want. Maybe something like All Music Shuffle:. Then create another folder the same way but call it sometihng like "Folk" or whatever genre you want. Then click and drag that folder into the All Music Shuffle folder. Create as many subfolders as you want in this manner. You can have folders within other folders several layers deep. Then put whatever tunes you want in each folder. Then when you wantt to shuffle between all those various playlists just go back and play the one root folder that contains all the subfolders (in this case the one called All Music Shuffle) then click on the shuffle icon and it will shuffle between all the playlests that are within the varous folders and subfolders inside. I probably didn't explain it that well, but if you just good around with adding playlist folders and then dragging them into each other and then putting playlists within them you will figure it out. Good luck.
