I have to be honest... The shows just don't hold up for me. I caught a few of them on Netflix and the shit just isn't funny. When I was a kid, I suppose it was exciting to be watching something that was controversial animation, but now it's just fucking retarded. IMO the best part of that show was the commentary over the videos. The rest was just filler, which is the opposite of what the point was, I suppose.
And Re: modern videos. The original B&B was reviewing "modern" videos, but they were all vids by mostly unknown artists. If I turn on Beavis and Butthead and see a fuckin' Gaga vid... I'll find it interesting but it wouldn't be the same thing as watching White Zombie or Korn before anybody ever knew who the fuck they were.
