I think Endless Sorrow is definitely your best bet for this with F&E and Far Away being a second and third. Perhaps even talkin' 2 myself. However, unless Endless Sorrow, these have much weaker stories. All her other PVs show weak references to utopias and dystopias. Some would say alterna but it's hinting towards reality if anything. Additionally, just smiling and being surrounded by happy colours does not mean it is a utopia. It is just a pretty video.
