My video for this achievement.
First of all, it's not that hard if you practice this song and learn to memorize it! For the first move, where you swing your arms around and then lift your leg and arm (this move returns quite a lot in this song), I had to exaggerate this move by swinging my arms more then the dancer, and lifting my leg higher. Try it around a little bit. When I did it the normal way, I would fail this move 75% of the time. I still got an Ok or GOOD quite a lot with this move, but hey, it's better then losing the multiplier!
Be aware that the game has a little video lag with the dancing that I do.
As you can see, it registers all my moves a little later, therefore you have to dance a little ahead of the dancers on screen, then it will register your moves at the same time as the dancers, therefore giving perfects.
Any questions, feel free to ask down here or send me a PM.
