The trouble with URLs is that they generally divulge very little in the way of context, especially when it comes to titles. Are these addresses for Just Dance: Floor, or Just DanceFloor? Just Dance: Floor would be a really terrible play on words, since the next Just Dance game in the series would be the fourth one. But, if it's Just DanceFloor, why is "Floor" capitalized?
Okay, now the word "floor" just looks weird.
