Multi-Tag is an ID3 tag editing program that allows you to apply the same
tags to multiple files. This is useful when you want to add the same Artist,
Album, Year, Genre, URL, or Comments Tags to a group of files. Multi-Tag
version 2.0 supports ID3v1.1 and ID3v2.3. It also allows you to remove tags
(either ID3v1.1 or ID3v2.3) from a group of files. You can also copy tags
from ID3v1.1 to ID3v2.3 and vise-versa.
