I'm trying to find a way to add a keyword or group of words/tags/strings to a set of selected iTunes tracks if they haven't been added. A use-case would be to add extra metadata in a comment such as (live) or (remix).
If some tracks previously contained (live) while appending, then it would not append it- only the non-matched files. So a comment tag containing (remix)(fast)(accordion)(random) would become (remix)(fast)(accordion)(random)(live) afterwards. However, if reapplied, it would skip this track.
The well known Doug has an append to tag script, but it doesn't have any detection capabilities. I peeked into the code (by right click > Show Package Contents) and can't seem to wrap my head around editing the script.
Anyone know of an existing script or a way to modify the existing script?
