Ghostbuster theme song in Rock Band? Too bad for me.

I was searching for stories on Kotaku and I saw a story that caught my eye. I clicked the link and I couldn't help but chuckle a little because of the photo that appeared. It has the main cast from the Ghostbusters film with Ray Parker Jr, the artist behind the movie's theme song, dancing in the street. He was interviewed on Eurogamer and stated that it would be a real cool idea to have the theme song in Rock Band. This saddened me because i only own Guitar Hero: World Tour. If it does come out, enjoy it Rock heads!
