[MPRIS] Extension of the spec with MusicBrainz tags

[Marius Orcsik]

Hi everyone,

I am developing a small user daemon[1] that listens for MPRIS signals and
uses the information to submit songs to last.fm/libre.fm and
listenbrainz.org

The later of these services requires data from some of the MusicBrainz
IDv2 tags in order to form a complete submission.

However this information can almost never be found in the MPRIS
metadata, as there is just one media player - that I know of - that
extended their implementation to contain them. This player is
Rhythmbox.

I would be interested if there is any interest in adding the
MusicBrainz tags to the MPRIS spec. These tags are already present in
the Xesam ontology[2].

Thank you and best regards,
/Marius Orcsik
