I want to know the answer to the following question:
What is the primary use of Compact Disc + Graphics?
All the background I'm provided with is that "The disc can be played on a regular audio CD player, but when played on a special CD+G player, it can output a graphics signal (typically, the CD+G player is hooked up to a television set or a computer monitor); these graphics are almost exclusively used to display lyrics on a television set for karaoke performers to sing along with.". Is that enough to answer the question?
