Basically what I want to do is to add the text [Instrumental] to a lot of tracks at once, but when I select many tracks and press ⌘I, I don't get the lyrics field. So, for starters, doing this from iTunes by itself is impossible. Then I went to Doug's Scripts and found only two scripts. One deletes the lyrics of all the selected tracks, while the other one copies the content from the clipboard to the currently selected or playing track, though it works only with one track at the time. So, again, no-go. Now I'm out of ideas and a hand would be welcomed.
