There's no world dance floor, it's just chalenging other players best runs. It's not even challenging in real time, its there best from whenever they played. Which could be weeks ago...
Songs are curated for boomers, gen alpha and dramatic highschool gen z. Not really worth the money but if you want newer songs you have to buy the newest game, even if you have justdance+.

Corporations are truly milking as much money as they can ðŸ˜
