I'm high on life, still hustle, tell them bastards I'm on
This is a pun. He says that he is “high” and then says “I’m on”. “High” we all know means high on drugs and “I’m on” also refers to being high on drugs. However, since D-Pryde does not use drugs, he is saying that living his life the way it is as a rising rap star is similar to feeling that high that so many people get addicted to. Essentially, he is addicted to his life as a rapper.
