I want to like it, but I had two problems that caused me to uninstall it. One, selecting a station by scrolling through the list was practically impossible: I could scroll down just fine, but as soon as my mouse moved over to select one, the stations would scroll all the way back to the top. I guess you're supposed to type in a keyword, so the list is shorter, but it should be possible to scroll through a long list if you want to.
Second, how do you turn it off? I wanted to listen to something else in Firefox for a few minutes, but if there's a control to pause or stop Worldwide Radio, I couldn't find it. (Ok, I guess it's streaming, so you can't pause it, but there ought to be an obvious way to silence it without silencing everything else.)
