I'm having a little problem with making my skulls sing. I need to get them to sing without them opening their jaws to the background music. I have the servo and servo audio/driver from Scary Terry. I'd like to be able to get them to sing with the music in the background but have yet to figure it out.
Here's a video of something similar that I want to do.

I know I have to seperate out the voice from the backgroud somehow, but I have no idea how to do that. Help anyone?
