EasyTag

EasyTag (stylised as EasyTAG) is a graphical tag editor that is part of the GNOME project. EasyTag runs on Linux and Microsoft Windows, and there was an attempt to bring EasyTAG to OS X circa 2014. It is written in C and relies on GTK+ and id3lib for graphics and ID3 tag handling respectively. As of version 2.1.1, EasyTag also uses the tag manipulation library provided by the MAD project, for support of ID3v2.4.

EasyTag is free and open-source software subject to the terms of the GNU General Public License version 2 or any later version.
