Here's a shock for you - almost a third of all Guitar Hero players are female.
"A very large group really wants great guitar music, and they don't want us to confuse that," Guitar Hero CEO Dan Rosensweig told Gamepro.
"And there's another group of people who love that, but also love to have more current music, more family music, music more popular for girls - 30 percent of our players are already girls, and we want that to grow.
"One of the great things about having a franchise like this is you can really meet all kinds of consumer demand."
