Don't. It's a mess of a game, just like Dissidia.
After you finish a song you have to look at like 5 different menus telling you how good you did, what you won, how you won it, what you unlocked, who unlocked it, who leveled up, who didn't, what the weather is like, how to make scrambled eggs, and how babby is formed
You are then taken back to the main menu, and can continue this vicious cycle of a game.
