Singstar and Buzz are over marketed, they regularly appear in the ads for the system. The market has simply decided that they don't want those games (though they have accepted the initially less heavily marketed Guitar Hero). The best they ever sell is a couple of million, hardly the breakout success needed to push hardware.
A game I'm developing with some friends:

It is largely a technical exercise but feedback is appreciated.
