Mp3tag - Universal Tag Editor

From time to time I find the need to update or add mp3 tags to lots of mp3 tracks simultaneously. I've tried all the usual music players but their functionality has always left me wanting more. In my search for a better "mouse trap" I've discovered Mp3tag. It's lightweight, allows for batch editing, and is insanely efficient. It supports a number of music file formats and also interfaces with the freedb database for tag info lookups. It works on Windows XP | 2003 | Vista | 2008 and it's free. Of course, if you download and love the program, feel free to make a donation.
