In Just Dance 2014, you can use Mojocoins to buy avatars as well as songs. There are 51 avatars that cost 5 coins, 9 that cost 50, and one that costs 500 coins. Do you need to buy the avatars, or just the songs? (And does this also apply to later games for which there are unlockable avatars?)

I want to run Any%, but I have a few questions. The rules say to "unlock all unlockables." I see that in the other forum thread, you mention that we just need to unlock everything and not worry about achievements (which I presume means reach Mojo level 62 on Wii U or level 33 on the other consoles). Is that accurate? Do we need to play any of the songs we unlock? The timer is supposed to stop when we get 5 stars on a song. How do we know when the song will get us to the required amount of Mojo? Does it matter which song(s) we play? Lastly, would it be allowed to use multiple controllers and/or multiple people to make the run faster for the songs with multiplayer achievements?

Thanks in advance, MrFun
