mp3Tag is a music tag processor for MP3, WMA, OGG and APE files with great features, like an automated search for lyrics/pictures and FreeDB support that powers automatic tag filling option - works great for mp3 albums that come without tags and meaningless file names, like 01.mp3, 02.mp3, 03.mp3, etc. The program takes the track lengths and compares this information with FreeDB data to find the appropriate album to import tags from.
