No matter how good (or bad) they are at it, everybody likes to sing -- in the shower, in the car, wherever. That's why karaoke is so popular. And now, America's biggest karaoke competition heads to network television with "Karaoke Battle USA." Thousands of wannabe singers take part in the competition in regional contests at venues across the country. The best make it to the national competition, held in Los Angeles, where a king and queen of karaoke will be crowned. The prize package includes a recording released by Hollywood Records and a spot in the Karaoke World Championship to be held in Ireland.
