As Joe pointed out in the bug report, this is probably fixed in the latest mutagen release.
Update the python-mutagen package using the QL stable PPA https://launchpad.net/~lazka/+archive/ppa or install the package directly: https://launchpad.net/~lazka/+archive/ppa/+files/python-mutagen_1.20-0~ppa2~maverick_all.deb In QL enable the "force write" plugin. Switch to the "Search Library" view, search for ~format="Windows Media Audio" select all songs and right click -> Plugins -> Force Write. If you have any further questions, ask away. regards ** Package changed: quodlibet (Ubuntu) => mutagen (Ubuntu) ** Changed in: mutagen (Ubuntu) Status: New => Confirmed -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/705936 Title: Quodlibet corrupts sometimes WMA files after editting the tags -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
