Best Answer
In Automator app, create a new quick action. Select the option “folders” for the item “workflow receives current” and select Finder app as your choice for the application to run this service with.
Next, add an AppleScript action to your workflow and insert this following AppleScript code into that new action.
You can save your Automator file now and name it something like “Play in iTunes”
Now all you need to do is right-click on any folder containing your audio files that you want to be played in iTunes, and select the menu item item “Quick Action” / “Play in iTunes”
This will create a new playlist in iTunes with the name of the folder containing your audio files and will start playing that playlist immediately.
If you don't want that playlist to be permanent and you want to remove the files after listening to them… sounds like a good little project to get your feet wet with by adding an additional code that will do that for you.
As a side note, you may need to add more audio file formats to the first line in the AppleScript code.
Anyway I think this is all a good starting point for you
