It doesn't quite sound like that's the intention here.

"We've tested the new Grooveshark in modern versions of Firefox, Chrome, Internet Explorer, and Safari.

It looks like you aren't using one of these browsers."

I guess ask them, but to me that reads like "Recent versions of these browsers have been tested. You aren't using something we have tested on."

Good job, though, Grooveshark folk! I love the updates so far.
