I dig it - manages to add some color without overtaking the usability/legibility of the browser interface really well. Only suggestion (if it's not too hard): consider maybe even shrinking down the 'record' image itself so that it's more clear what it is. Knowing what it is, I can tell it's a record...but others might just think it's a vaguely circular red graphic item....not bad looking either way tbh, but there might be a 'perfect medium' size where you still get the impact of the red corner + it's obvious what the graphic is underneath the interface.

Either way...it's one of only 3 that I cycle through now to show some untacky music love to my browser, so thank you either way!
