Can't say I like it myself, sounds very post-grime and not the type of thing I was hoping for based upon the marketting so far (personally wanted something more organic, mystical, Asian and timeless myself - taiko drums, gongs, panflutes, erhu, guzheng etc.).
I find that piece very monotonous and if it plays over EVERYTHING like MK11's did, I can see myself switching the game music off very quickly, as I did with MK11.
Would personally love to hear music more like this in the games (for me Shang Tsung's Garden is the best MK arena theme I've heard since the mid 90s):
