UltraStar Deluxe is a free open source karaoke game for your PC. The gameplay experience is similar to that of the commercial product SingStar™ by Sony Computer Entertainment, which is exclusively available for the Playstation®.

Unlike SingStar™, however, UltraStar Deluxe allows users to create their own songs and sing them on their PC.
