I've Googled for apps to do this but all of the ones I've found are out of date. I realize there isn't much of a need for this anymore but I've just discovered about 20 tracks in my library are still protected. This means I can't use them in iMovie for the iPhone. Only about half of them are listed in iTunes as having iTunes Plus upgrades so I'm trying to figure out what to do with the rest. What's the easiest way to do this nowadays?
