It's most likely a copyright thing. Certain songs have strict ownership around it that makes it expensive to include the original in Just Dance, so either they exempt it from the list or cover it to make it work. This is less common in 21st century tracks because the original owners are still in power and think of Just Dance as positive publicity. It's not that Just Dance thought this would be better; it's just that they didn't have much of a choice.
