As a member of the Grooveshark development team, I must say it’s quite a pleasure to see the fruit of our labors being used this way. As you say, presuming that school content-blockers don’t get in the way, teachers could potentially use Grooveshark Lite as a resource in all sorts of neat ways. It’s a facet of the product that I think neither I nor my peers have considered, and I’m thrilled to see it used this way. Thanks for doing what you do, and for giving Grooveshark a go!
