Ben Horowitz introduced the founders of Rap Genius at DLD. Conference attendees were kind puzzled— Andressen Horowitz invested in a website that explains the meaning of rap songs? This site is hilarious and ingenious and with 10 million uniques, is no joke. I can see why they invested $15M in a site that gives the ability to annotate any page on the Internet with commentary and additional information, thus creating a community of actively engaged music fans. Their platform could eventually reach way beyond making sense and folly of rap/hip hop lyrics and serve as the “Internet Talmud,” or the knowledge behind the knowledge. Coolest part is that the musicians can actually verify the meaning of their lyrics.
