User blog:DavidG185/Toughest/Hardest Routine in Just Dance

Hey guys. I have learnt that Hey Boy Hey Girl from Just Dance 3 is one of the hardest routines/song in that game. But I would like to know from you guys (just for curiosity)...

'''What is the hardest song/routine from any Just Dance Game so far? It can be something that you already played or something that is coming out.'''

I also learnt that this song came out the year I was born in, aswell as Soul Searchin' . You learn something every day when looking at this wiki.

So what are your thoughts. (The question is bolded).
