In the Wii There is a Game Called American Idol What is That About? is It Part of Wii Karoke?

It is a separate game. It follows the lines of games like Rock Band and the new Guitar Hero series. You must sing along with the game scoring points.

Suggestion:

I own both of the American Idol games- and yes, they are Karaoke games. If you like to sing and have fun with friends, it's a great game
