I'm sick and tired of people talking about how important it is to have complex lyrics. You are not a nice emcee because of how many metaphors you can spit or how complex your vocabulary is. It is a nice feature, but that's about it. All that doesn't mean shit if you don't have exposure or if people can't relate, it just means you can write.

As for your question, to me there is no such thing as a "Real" rap song because everyone has different views and experience's with reality. What one might thing is real, another might think is total bullshit, and vice versa.
