IGN spoke with Eric Brosious, audio director for Harmonix, about selecting songs for the upcoming Rock Band 2 release
. He talks about balancing difficulty between instruments, bringing a wider range of genres to the game, and his view on the competition for songs and artists between Harmonix and Activision.
"We prefer not to sign exclusive deals with artists because while it seems like the competitive 'business' thing to do, in the long run, it's really not good for anyone. We think we should be working to get more music out to more people."
