Kid3 is an audio tag editor for KDE with support for editing tags in files such as MP3, Ogg Vorbis, FLAC, MPC, MP4/AAC, MP2, Speex, TrueAudio, WavPack, WMA, AIFF and WAV. The latest version, 3.3.0, brings some new features, including support for lyrics.wikia.com, chapter and table of contents audiobook frames, and a new ‘defaults’ button in the Settings window.

Kid3 has features such as multi-tags editing, the ability to generate tags from filenames, generate filenames based on contents of tags, importing of tags from services like MusicBrainz or freedb2.org.

Support for lyrics from Wikia (will be opened in a web browser):

In addition to the new features, this version benefits from a few fixed bugs, like the ability to now remove id3v1 genre tag or a build fix.
