Write musicbrainz_discid tag when disc is unknown

[xmixahlx]

whipper writes the the (useless...) title, artist and album tag fields when the disc is Unknown, but does not write the musicbrainz_id tag field, which would be rather useful.

I resolve this by adding the tag in Ex Falso manually, but it would be nice to avoid hunting down the value and avoid copy+paste errors.

FYI to fix Unknown Disc details: I rename the files, then use a "Tags From Path" formula and "Edit Tags" to review/fix/add. Similar naming and tagging functionality would be nice in whipper.

Thanks for proposing this feature.
There are lots of musicbrainz_ tags:

musicbrainz_trackid
musicbrainz_releasetrackid
musicbrainz_artistid
musicbrainz_albumid
musicbrainz_albumartistid
musicbrainz_discid
musicbrainz_originalartistid
musicbrainz_originalalbumid
musicbrainz_recordingid
musicbrainz_workid
musicbrainz_releasegroupid

Which one(s) exactly are you asking for inclusion?

Related to #200.

If the disc is otherwise unknown, the only MusicBrainz related ID that makes sense to add is the musicbrainz_discid. All the other depend on the disc being known.

Understood, thanks!

I think it makes sense to always add the musicbrainz_discid tag (not only when the disc is unknown).

EDIT: 🤦‍♂️ It gets already added (only missing when unknown)

Since thomasvs/morituri#77 - yes. ;)

@Freso, @MerlijnWajer I think this Google Code-In task should be closed (already completed). 😉
