Hah, that's pretty trippy. The boat on the water and the towers swaying down were the best, and I was really trippin on leela. The music was insane. It definitely added more to the experience and may I suggest to the future viewer to turn the speakers up and watch the whole thing. You won't blink because the waving sucks you in.
That song sounds like an old German polka I knew. It's no doubt the song I used to play when I was a kid at the German grandparents house. To see it here on a minecraft video is blowing my mind because I haven't heard it since. lmao. Any Germans know this fine polka? I'd like to hear the original. It should be much slower.
