Based on Marc's reasoning given on the site, sounds like they have an easy pivot into annotating everything if the rights issue takes them out of the lyrics game...
But if the rights issue wasn't there, wouldn't Google build a competitor in a few days? It's a fairly simple website to make, and lyrics websites do a ton of traffic.
Google built something similar years ago--not a direct competitor to RapGenius, but rather a generic annotation platform for the Web.
Guess what? It's now discontinued: http://www.google.com/sidewiki/
It's not trivial to build annotation platforms that are both compelling and easy to use. Hat tip to RapGenius!
