So basically, Rap Genius is just a website explaining what lyrics of a song mean with no revenue model? Not only sounds this like a not very significant idea, the approach to music is very questionable.
It doesn't matter what the lyrics mean to the artist or some expert. The only thing that matters when listening to music is what those lyrics mean to YOU!
Seems to me that Rap Genius is corrupting that concept.

A lot of lyrics are full of obscure references and complex ideas not easily understood. Perhaps especially in rap. So explanations save you hours of work in trying to understand and appreciate the lyrics. For example:
