Marc Andreessen said in a statement on the site (annotated, of course) that Rap Genius has the potential to “be knowledge about the knowledge” and to “create the Internet Talmud.”

The site was founded by Lehman, Mahbod Moghadam, and Ilan Zechory, classmates at Yale who had a brainstorm in the summer of 2009 over an examination of Cam’ron lyrics.

After a summer at the Y-Combinator in 2011, Rap Genius emerged as the tech incubator’s fastest-growing company. It now boasts over 10 million unique visitors a month, delving into lines like Lil Wayne’s “real Gs move in silence like lasagna.”

“I often wonder how the Internet would have turned out differently if users had been able to annotate everything,” Andreessen wrote, recalling a feature that never made it into Mosaic, his seminal web browser. “And so, twenty years later, Rap Genius finally gives us the opportunity to find out.”

All the stars may be aligned, but how Rap Genius scales from “rap Wikipedia” to “Internet Talmud” remains to be seen. It’s unclear whether a site fueled by hip-hop obsessives can attract a completely different audience, united only by a desire to decipher the Internet’s endless content.

“There is plenty of room for growth in the genre, but you can imagine it becoming a sort of cultural Wikipedia that explains all kinds of things.”

“For us, rap was great,” Zechory continued. “Starting with one thing where you can get the passionate community going is the best way to approach it.”
