I'm not exactly computer savvy, but all your bar does is take you to google...
Wouldnt people be less confused using google?
Or one of the many google toolbars for webbrowsers? Mine is in my top right corner, along with a wikipedia one.
And also, I type in "World's End Girlfriend" and it takes me to google with "World\'s End Girlfriend", and asks if I meant "World's"...
So as you can see, apparently your bar doesn't handle apostrophe's very well. May not seem so bad, but for something like an obscure band name, it makes all the difference in the world.
I'd call it anothersearchbox.com
