MP3tag DLL

Hi

I was using MP3tag years ago, and thought that there is a library for various actions like writing tags and so on. Just recently I have a need for that exact thing, to be able to call what I imagine are in the DLL's API, like reading writing/witing tags. In my case I'm using Python, but would be just as happy with any other language (that came across a but pompous, I'm by no means that good with any language).

Does this still exist? It'd be tremendously useful

TIA
Rob

Mp3tag is still proprietary software.
