I have it on very good and not at all fruitcaked authority that rock and roll is the devil's music. It corrupts the minds of young people, turning them all into savages that breed and destroy in an orgy of murder-boinking that caused the end of the America we all remember so well. Or, you know, not because I just made that up.
Still, I think that even rock's most vocal supporters would be willing to admit that darkness has always been a pretty integral part of the genre. Darkness is cool, always has been. That's why we have parties at night.
While that may be the case, the movie industry has occasionally enlisted rock and roll as demonslayers, and today we celebrate the top five instances where only the power of rock itself was awesome enough to beat back evil.
