From Magnus Brading Software:
All-in-one mp3 toolbox. Fast, extremely powerful and very easy to use.
Acclaimed by thousands of users for its speed, ease of use, stream-lined interface, and complete functionality. All string manipulating tools are based on the same advanced template/parser engine that is well known for its ease of use and stability. Highly configurable auto letter case fix and auto substring replacement can be used for all operations. All mass processing operations can be fully controlled using the extremely configurable and powerful processing filter. All batch processing operations can be performed in preview mode, where no actual changes are made, and they are also fully undoable once they are executed for real. It is so tragically easy to drown in the overwhelming plethora of mp3-tagging tools, but just take a quick look at Mp3/Tag Studio and you'll know what we mean when we say that you will never have to look for another such tool again.
