Thank you for stepping up.

I got something like this:

...which looks easy enough to parse.
Unfortunately, installing pytaglib on my Trisquel machine was as much
work as emms-print-metadata. It involved manually downloading
pytaglib-0.3.4, then installing cython, then:
$ python setup.py build
$ python setup.py install --user
But I assume that it is easier on systems with pip, so this isn't a
show-stopper. Moreover, it shows that this can run on a completely free
system. If it couldn't then that would be another show-stopper.
As an aside: looking at the command line of pyprinttags I note that
we'll have to add the "-b" (batch) option so that pyprinttags doesn't
try to ask the user questions and hang the elisp process call.

Absolutely option 1, since otherwise we would be shipping C, C++, Perl,
and Python; no thank you. The idea is to let the OS provide the
packages, and let elisp do the rest. This is as opposed to what we do
now, which is: let the OS provide a package, provide some glue code, and
then let elisp do the rest. We are trying to get rid of the glue.
I can write an implementation of emms-info-pytaglib and ping you to test
it once I'm done, or you can do that. It really depends on whether you
feel like writing that would be fun for you; your choice. Thank you
nevertheless.
