OK, I'm contradicting myself by making this topic into a discussion, but here's an example of what I'm talking about

This video is 20 years old, but the music group which owns the rights to the group's material has posted a very high-quality version on YouTube. And you can tell that they must have had an armorer during filming who handled the blank-adapted Tommy Guns, 1911s, and sawed-off shotguns. I'm sure some of the armorers on IMFDB have even supplied their weapons to music videos and can tell stories about working with the artists.
Of course, there is a very big difference between a video like this (which has the production values of a generously-budgeted Hollywood film) versus music videos that rely on collages of images. For instance, this...

...is something I'd be opposed to including, because all of the guns are just pics which look like they could have been taken from a Google search and then made into silhouettes.
At the very least, we would need to provide guidance to members about what are appropriate types of music videos to include. And in general, whenever we have to articulate complicated rules and standards for inclusion, there are always people who don't pay attention or don't care...
