iTunes does not seem to want to add MP3s. I drag and drop, nothing. They are not added. If I double click on the MP3 it's played by the app, but it's not added. I've checked over everything, now I'm turning to the collective wisdom here. I'm on a W*nd*ws PC using 16.4. It's authorized, the proper directory is selected. I checked all the obvious stuff. And before you ask if I googled, yes. And I found fixes dating back to 2007. Nothing recent with 16.4.
