MusaTagger is a very complete tag editor,
supporting most of the features of id3v2. It is
built on GTK+ 2.0, and it supports automated
renaming of the songs, tagging multiple files at a
time, play counting and rating, as well as the
more basic features any decent tagger should have.
MusaTagger is a part of Musa, which will be a
full-featured jukebox for Linux.
