Colione98 - Thanks for taking the time to write that - here are my responses :
There was one video I saw where the dj had placed the camera next to one of the cd decks, and you could actually hear them moving the platter, shifting around, talking, hitting buttons etc. - this did not do the music any favours.
I wish I could post up an example of the kind of thing I'm talking about but I can't on principle - it would be unfair to them.
I guess what I'm saying is "If you're going to do this, do it at least halfway well". Whereas the kind of thing I've seen recently is anything but. When the video becomes more about looking at the person standing there posing, and less about the music, then we have a problem.
