I know, this isn't a question, or a technical problem, it's a 'thank you' post.
I'd been using MP3tag for quite some time when i just ran Windows, but about 5/6 months back i switched to Ubuntu (love it, but that's not the point of this post), and sadly, there are no plans for a native Linux version, but that's OK. MP3tag runs just fine under Wine.
I'd have hated to not have MP3tag available to me.
There are many great tagging apps out there, but none have come close to matching Mp3tag.
Keep it up!
