Andreessen Horowitz Invests $15 Million Into Rap Genius

Andreessen Horowitz has invested $15 million into is a website that explains what the meaning of rap lyrics mean for all of the latest songs.  Andreessen Horowitz partner Ben Horowitz is a rap fan.  Rap Genius uses crowd-sourcing to find out the meaning of the lyrics and they were a Y Combinator company.  Below is what Marc Andreessen had to say about the funding:

“I’m delighted to announce that Andreessen Horowitz is investing $15 million in Rap Genius.  Given that Rap Genius is a web site where people explain rap lyrics, and given that my partner Ben is a noted rap fanatic, your first reaction might be, “That Horowitz guy has completely lost his mind. I, on the other hand, find rap every bit as comprehensible as ancient Mesopotamian. That’s why I’m writing this blog post – not him. Let me explain why we’ve invested in Rap Genius…

First, there is the undeniable, irrepressable phenomenon that Rap Genius already is – the definitive online community of rap aficionados; one of the fastest growing web sites in Y Combinator’s history.

Second, there is the stellar team. Rap Genius has the rare balance you always hope for in a startup team – three founders, each with unique skills, who mesh perfectly. Mahbod is the most brilliant community creator we’ve seen since Caterina Fake’s heyday at Flickr. CEO Tom shares Jeff Bezos’s D.E. Shaw pedigree and codes up a storm. And former “Deadwood” writer Ilan  serves as impresario and runs the show; a thriving ecosystem of ideas, artists, and fans.

He added:

Back in 1993, when Eric Bina and I were first building Mosaic, it seemed obvious to us that users would want to annotate all text on the web – our idea was that each web page would be a launchpad for insight and debate about its own contents. So we built a feature called “group annotations” right into the browser – and it worked great – all users could comment on any page and discussions quickly ensued. Unfortunately, our implementation at that time required a server to host all the annotations, and we didn’t have the time to properly build that server, which would obviously have had to scale to enormous size. And so we dropped the entire feature.

I often wonder how the Internet would have turned out differently if users had been able to annotate everything – to add new layers of knowledge to all knowledge, on and on, ad infinitum. And so, 20 years later, Rap Genius finally gives us the opportunity to find out. It’s an ambitious mission, and one we are proud to get behind.
