I have not found a karaoke machine that makes you sound good when you are not that good.
And the guy who invents that is gonna make a ga-ba-gillion-million-billion dollars. Every bar. Every American Idol-like show. They'd all use it. Even American Idol already uses a harmonizer for its contestants called AutoTune so that they don't sound as off-key as they actually are.
