Monocle just launched a internet radio service at monocle.com/monocle24.
Since I don’t want to leave Chrome open just to listen in, I run a Fluid instance of the page.
Note: you can actually use Fluid for a lot of sites you use as applications, e.g., http://teuxdeux.com/, https://app.getflow.com/, http://facebook.com, http://tumblr.com.
