What I really need is an app that can quickly identify and fill in missing or incomplete tags so I could use the program routinely before transferring newly downloaded albums to my iPod nano. Is there anything like that?
I think you can try taghycardia, it seems to do just what you need. For the owners of ipods, it's a no-brainer. Just run your albums through the program with the default settings.
