Translated version

[jesus2099]

There is a work-work “later version” relationship to link the 2 versions of the song.
You can check the “translated” option of this relationship.

Update: I found this post, while moving this topic to its category and tags, in other words:

Translations

Your first thought is correct. You can add a new work for the translation, link the two works with the “later version” relationship and the “translated” attribute, and add both the translator as translator and original writer to the new work. See for example: https://beta.musicbrainz.org/work/05bbfd2e-0f31-30ab-ac12-66a4c3c42263

You can find many answers in the forum.
