Hello, I was working on a WavPack plugin for libtunepimp, and side product of this plugin is a separately usable TagLib add-on (if you implement a custom FileTypeResolver). In case anyone is interested, source code is here: http://svn.musicbrainz.org/libtunepimp/trunk/plugins/wv/ (you can ignore the wv.cpp file) Cheers, Lukáš
