if i don't confuse, it is useless fictional language.
we could add all fictional languages (like hey this song is said to be sung in martian by the writer).
it's used on one release and zero works in total, and it could look more nerd than funny IMO.

1. replace all Klingon → Artificial (Other)
2. drop all Klingon

where all Klingon = 1 release and its pseudo-release.
