At first, I thought I had opened FF14—wonderful track! Also can't figure out the language, it almost sounds like a bunch of languages together, like at some parts it sounded Japanese, Chinese, Italian, and Simlish(??)
Some writing technique were from Final Fantasy and Nier Automata (though I never played the game before).
You guessed Japanese and Chinese correctly and that they're 4 languages that the singer is singing in.
