TagsRevisited is a playground for new technologies the author tries out, so it offers for example Unicode support, Pascal scripting, MusicBrainz lookup and more. It currently reads and writes ID3v1.0 / 1.1 and ID3v2.3 / 2.4 tags, and reads VorbisComments from Ogg and Flac as well as Wave-Tags. It also offers cover downloads through a Google (or other, custom defined search engines) image search.
