PlayTune on new document in a view category - how?

I have a user that wants to know if it is possible to play a tune when a new document is created in a specific category in a view.

This would alert the user to the fact that there is a new document instead of them having to constantly monitor the database.

Obviously the database would have to be open, but Notes could be minimized.

I know how to use PlayTune. I am just not sure where to put the code in the view to trap a new entry and check if it is in the proper category.

Any suggestions?
