In the last couple years we collected a list of songs and translation on this website which are written in languages for which we don't have a category yet.
Those are languages for which we have less than 3 texts.
Up until now, this list has been only accessible to moderators. However, there is no reason to keep it hidden. Therefore I now make it available to all of you so that these "rare" languages may get more attention and so that everyone can contribute to the list.
If you add a song or translation in a language without category, it's very appreciated if you mention it in this thread!
At its end, there is also an (incomplete) list of songs where we don't know which language it's written in - for this, we need your help :)
(even more such songs can be found here: https://lyricstranslate.com/en/language/unknown-lyrics)
