Can you understand words in this songs?

[LeoNeo]

I'm not native speaker, but I want to know can you understand words in this songs? Maybe can you say about accent of vocalist? I want to know your mind, because I watched reaction on YouTube and guys who listened this songs said to vocalist singing incomprehensibly.

I don't understand what they are speaking at all. I haven't heard this language used in the song's chorus. Even the English they speak in between is blocked by the song's instruments noise. But the song sounds cool.
