Anyone that’s using my Zune Marketplace Mp3tag source will probably want to upgrade to the latest version of Mp3tag, which as of today is 2.40! I’ve been using the beta version for awhile and the tagging dialog is much better than in the original 2.39 release, easier to tag those albums where you only have a few of the tracks.
Get it from the official download site.
In a related note I’ve been using Mp3tag for about 2 years and I finally pulled the trigger and donated some dosh to this excellent free program. Thanks to Florian Heidenreich for continuing to create such a great product!
