This morning, Google released their annual Zeitgeist—a roundup of the most popular search terms on the web throughout the year. We’re thrilled to announce that in 2010, Grooveshark made the list of the Top 10 Searches in the United States.

Coming in just behind Facebook, and just ahead of our guilty pleasure the popular TV show Glee, Grooveshark comes in as the #8 most popular rising search in the United States for the year.

And it’s not just the United States! Grooveshark is ranked third in Argentina—ahead of Twitter, and just behind the Bieb—and ninth overall for entertainment globally.

Showing up on a Top 10 list including the iPad, Chatroulette, and Justin Bieber is what compelled us to start Grooveshark originally. Now that we’ve achieved our goal, we’re excited to keep updating the just-launched revisions to Grooveshark, shop for last-minute holiday gifts, and make 2011 even more awesome.

Thank you, Grooveshark friends. New and old, you never cease to surprise and delight us.
