It's a mix of languages: I see here Polish, Russian and Czech
Is there any more language here?
Or may is Interslavic?
I am a native Russian speaker who understands about 80% of the sung.
What a sad song!
At first I thought it was Russian
This band sings in different Slavic languages so I want to make sure if it's not one of them
Voron, tuman are Russian words
We had this discussion in the past. Verdict: constructed language (based mainly on Polish, Russian and a bit of Czech)
So I will report it to be changed to a constructed language
