I'm so late on the theme... I know. However after some new changes in Chrome it's become possible to accomplish what I wanted; touch on a bit of effort and we have success.
The theme is currently being checked by a tester (SugarD) and will be published publicly to the Chrome app store tomorrow granted everything goes okay and doesn't spontaneously meltdown.
You may need to disable the new "onmi new tab page" in order to do this you navigate to:
chrome://flags/#enable-instant-extended-api
and set the option to disabled. This isn't required but strongly recommended, it looks better with the theme. If you are using the current dev build this option is no longer possible which of course means it'll no longer be possible on the stable channel in a few months.
Argonath Radio for Chrome (beta) version 0.2 will be published sometime tomorrow as well.

Nasty looking UI which will see redesign eventually

This is a Chrome app not exactly an extension. The previews do not represent what it looks like upon release. I have a handful of design tweaking to do.
