Dance Central 2

This one requires a second player, a cardboard cutout does not seem to cut it (don't ask). However all you have to do is win, which means your "friend" can simply stand in place while you rack up points.

First thing to note is that Dance Battles are much longer than the original song in Perform. So make sure not to tire yourself out by doing this.

Secondly, difficulty does not affect how you score. Someone playing on Easy will score just as much as someone on Hard if they play just as well.

Also, make SURE you are playing as the profile who wins the match, and actually win the match. If you haven't set up Kinect ID for yourself (or haven't got one) the game has a habit of switching you around.

One glitch that came up from time to time was that there would be no flashcards after a Free-4-all, but you are still required to play through the song. I couldn't figure out a way to make them instananeously appear back, so you might as well live with it until it is fixed. They'll come back for you if and once your opponent finishes a solo part.

To add: shortest songs
