I made this script to give you one-click access to multiple moods.
It only works for the currently PLAYING song.
You need to save it in the Auto scripts section as a .vbs file, and reload media monkey.  It will create a dockable panel.  If you close the panel you can reopen it by going to the View menu, go to the bottom, and it's "Mood Setting Panel"

When you click one of the mood checkboxes, it adds that to the mood for the song if it's not already on there.  It also adds the semicolons for multiple moods.

By editing the below code in the places I marked out, you can change the position and number of the checkboxes as well as the genres you want them to set.

It should be easy enough to modify the code to make another panel that lets you do the same thing with Occasions or any other text field. 

I hardly know VBScript or Mediamonkey programming so any requests on this I will not be able to do, someone with more time and inclination can pick that up for you!
Enjoy

I would like to thank Mediamonkey's dev team for making such an awesome product that allows you to do so much on its own, and then expand it using code.  Beats Itunes easy.
