Eminem paraphrases Snoop’s -izzle (“wizzle” instead of “nizzle”, since Eminem is forbidden from using even the -izzle version of the N-word) as a symbol of pop-rap crossoverism
In this line, Em is just saying “is it a miracle that I was successful, or a perfectly normal and logical cause / effect?” Pop fizzing up is not a miracle, it’s a normal occurrence because soda is fizzy
