Take center stage with Karaoke Revolution! Turning the
PlayStation 2 into the ultimate karaoke party machine, Karaoke
Revolution is the only interactive karaoke game to score gamers
on pitch and rhythm with a virtual audience reacting in real time
to their performance. Karaoke Revolution features a dynamic in-game
audience that reacts in real-time to each note sung, resulting in a
wild crowd backed by an explosive light show for a great performance
or disappointed spectators walking away from the stage when the
performance is weak. Designed for amateur singers of all ages
and all levels of musical abilities, Karaoke Revolution brings the
only interactive karaoke experience into the gamer's living room.

With more than 30 hit licensed songs from the 70's, 80's, 90's and
today, gamers will have a chance to sing their way from small clubs
to the ultimate concert venue when performing in "Showtime mode."
For those pop stars that can't part with the mic, sing all night
long in "Arcade mode" or "Karaoke mode."

Features:
* Beautiful 3D environments make this the most interactive
  and entertaining karaoke product ever created.

* Sing along to licensed hits and well known classics and be
  judged on your performance.

* Give your best audience performance or suffer humiliation
  with crowds that react to your skills in real-time.

* Become the next pop star as you work your way up from singing
  on the streets to the ultimate concert venue.

* Special technology rates the pitch and rhythm of your vocals.

There have been players with that feature for several years.    It was called vocal scoring.   It would be ok for fun but i would never use it at a show.   Wouldn't want to insult or embarass anyone.    That would make it a singing contest.
