Actually doing it my way may offer an alternative method of saving to Playlist, after pressing Play on Album folder name go to Now Playing/Current Playlist (wording varies according to skin used) on the side bar menu, then if all tracks are listed there is a Save option on the sidebar in the Now Playing view. Not sure if this will do what you want with how you have your Files, but just pointing it out as another possible method.
