Hi

I love everything about my new sony walkman except I cannot get playlists to work... I have watched 5-6 videos about how to create and transfer them to the walkman but nothing is working. I know how to drag/drop etc but my walkman is not finding the playlist folders I create. I have tried simply pasting songs into the playlist folder, creating another folder inside the playlist folder for the songs, but nothing is coming up when i un-plug my walkman. 

Can anyone help?
