With my seven years of dancing experience, I tell you that bulletproof songs are difficult to dance, and it is even harder to dance well. The difficult movements of some songs cannot be effective without basic skills. Refer to "Teenagers Encounter Evil". Several idling and one-handed backflips should be practiced for at least a few years.

If you don't have basic skills, I suggest you start practicing from I like Pt.2 or converse high. Not today and fire belong to the advanced stage. The most difficult thing is Dope and the early Men and dancers, which belong to the technical aspects of big movements, great strength and great energy consumption, including the modern dance involved in the WINGS series. Modern dance involves a wider range and must be practiced for several years.

I played very hard.
