Comments and/or suggestions for plugin to calculate an albums LAME codec?

### Problem

I created a plugin that exposes an album template field called `albumquality`. I used portions of library [dnuos](https://bitbucket.org/brodie/dnuos/src) and converted the used pieces to Python 3.

Biggest feature of this plugin is that it will return the VBR quality between 0 and 9. If something goes awry, then `Unknown` will be returned.

I ran it over a few hundred albums in my library and it appears to have tagged everything properly.

I was wondering if anyone had any comments and/or suggestions?
