Part of the reason for that might be because your Wii U can't handle all the animations on the map at once, maybe due to too much memory on your console?

On all of those routines, the background is not a pre-rendered video like it is in some JD4 songs and all songs in the more current games. So for Call Me Maybe, it plays the video of the dancer but behind it is a whole bunch of images that are programmed to move, shake, zoom, grow, change color, etc. with specific timing and direction, so there's a lot more going on in those maps.
