It is a pretty simple game. You just pick a song from one of the 32 available. (I wish there were more you could unlock. Hopefully they will add new ones in time.) Choose whether you want to do a short version or the entire song. Pick a little avatar and you are ready to go.
As the song starts, a countdown will scroll across the bottom of the screen, followed by the dance moves you are supposed to do. The character on the screen will also model them. It would be nice if you got to choose a character.
It can take a bit of time to learn how to do the dance moves right so the Wii remote registers and you get your score of "Great", "Ok" or an X if you miss. I like trying to get a new high score.
My favorite songs to choose are:
