Is there an action that can be created to entirely remove a tag if the tag name (i.e. the name of the tag itself, not the tag's content) matches a certain criteria?
I'd like to remove all visible iTunes tags (I'm not talking about the hidden embedded stuff) and seeing as they all start with the same 4 letters "ITUN" (e.g. ITUNNORM, ITUNMPB, ITUNESMEDIATYPE etc.) then creating an action that removes any tag name starting with those 4 letters would mean that I don't have to look up every possible iTunes tag name and manually list them all under the 'remove fields' function.
Also, this action could then easily be adapted for other uses, such as to remove all tags that have names starting with "ORIG" or "WWW", for example.
Any help on how to do this would be much appreciated.
