The first video I saw in my life was Twisted Sister's "We're Not Going to Take it" and man, after hearing that song, changed my life forever. I love Dee Snider and Twisted Sister, grew up my life listening to those guys. Twisted Sister was a huge part of MTV back in the 80's. They pretty much dominated MTV.
I miss the old days of MTV when it used to be 24 hrs of music videos non stop.
