The choice of songs leaves a lot to be desired, unless what you desire is people screeching words like "reeeeeal" and "hiiiiiiiigh" over super-fast Japanese techno. There are some familiar pop hits here but not enough (12), they're mostly a bit old and too many of them are rubbish. And they don't appear to have been picked with any thought to how suitable they are for frenzied dance mat stomping.
Tracks like Rock Steady by All Saints and Lonely at the Top by The Ordinary Boys, for example, aren't exactly pumping disco hits. The Fratellis' Chelsea Dagger is all right, but having played SingStar we can confirm it's a lot more fun going "Da da da, da da da" 49 times with your voice than with your feet.
