what is karaoke karaoke discs?

Answer 1

Karaoke is music to songs without the words. i.e. you can sing with the music to your favorite song.

Answer 2

The karaoke CDG, also known as CD+G (Compact Disc plus Graphics), is very similar to a standard audio CD. The difference lies in the graphic data (lyrics and images) that is embedded in the unused sub-channel of the disc. The audio portion of a CDG can be played with a standard CD player. A karaoke player is required to display the graphics on a monitor.
