JUST DANCE 2015

You gain Mojo by finishing dances and playing online. It's pretty difficult to not earn Mojo by just playing the game (I've been playing this game for 7 months and have gotten over 20,000 Mojo). You spend Mojo by buying new avatars and Mash-ups. You can buy avatars by going to your Dancer Card and click on your avatar and you can buy new Mash-ups by clicking on every song and choosing to buy the Mash-up right next to it.
