What is the music from Skull Mountain at Sixflags Great Adventure (NJ)?

I went to Six Flags Great Adventure yesterday with two friends, and we got to ride the coasters a total of thirty-eight times because of the complete lack of any lines. We rode Skull Mountain at least eight times. We noticed that while on it, some metal music plays. We asked the conductor, but he didn’t know the name of the song, and had actually been interested in knowing the name of it himself. So, does anyone happen to know what song plays during the Skull Mountain Ride?
