Rules based on folder content

Hi guys,
Having spent the best part of an evening creating an arsenal of Hazel rules, I'm massively impressed! I've got Hazel to carry out most of the basic housekeeping tasks I have to perform on the regular.
I'm just struggling with one little thing that you might be able to help me out with...
Basically, I want to create a rule that does the following:
if folder contents is just audio files OR just audio files and images BUT not just images, then move the folder to x location
Does that make sense? I'm sure it's quite simple to achieve but I feel like I'm just missing something...
Thanks in advance
*EDIT* Had to make this a little more complex, worked out the initial problem
