TagScanner is a multifunction program for organizing and managing your music collection. It can edit tags of mostly state-of-the-art audio formats, rename files based on the tag information, generate tag information from filenames, and perform any transformations of the text from tags and filenames.

I use MusicBrainz Picard to find tag information and then TagScanner's rename features to whip my 10,000 songs into shape!!! Love them both!
