Rap is rap. A lot of words in 2 minutes. I didn't find lyrics (in russian) and it is hard to rewrite it from clip.
Overall meaning "Soon, I will come" is about "Hey, I am rapper Beck. I want to go to russia. How are you? I'm fine. I love Russia. Soon I will be there." and so on. It is fun - he mentioned Novokuznetsk city, where I live.
