Looks like audiotag can do that, here's a snip of the help; --rename-files rename files based on meta-data --rename-pattern pattern to use when renaming files. when no rename pattern is specified, the rename pattern defaults to: "%T. %a - %t" string replacement directives: %T: track number %a: artist name %t: song title %A: album name You can specify subdirectories in the rename pattern. "%a - %A/%T. %t" will rename and move the files. "%a -%A/" moves the files to new subdirectories without renaming.
