"...the video game "Rock Band 2," which along with "Guitar Hero" is rocking bars and living rooms across the country. Many songs' sales have more than doubled after release in one of the games, and well-known bands have started lining up to provide new music direct to the game makers. Now record labels - noticing what they are missing, and struggling as compact disc sales tumble - are looking for a bigger piece of the action."
