Edge of Time III by Phenelo is a pretty example of doing those landscape videos well. It features examples of living Azeroth -- things in motion, players moving around. It's not just a bunch of static scenery. Also, the music choice is excellent for soothing, chill background music. Edge of Time III would be awesome as a background dance video or just for a bit of relaxation time. Fair warning: The video is long.
