Re: looking forward to Emms 6.0

* Find a suitable replacement for emms-print-metadata as a way to access
  taglib. A current candidate is installing pytaglib.

I am happy to be involved in this.  If pytaglib is to be used, it comes with a small python script called pyprinttags which outputs something like this:

Clearly a little parsing would be necessary to get this into a shape that emms could work with.

I see two ways to go with this:

1.  write emms-info-pytaglib.el which does the parsing.

2.  write a python version of emms-print-metadata that is a drop-in replacement for the C version.

Both are easy though option 2 is probably easier.  The downside of option 2 is that we still have a piece of non-elisp to install in the user's path.

Preferences?
