This is very cool. It worked perfectly even in the dimly lit room I am sitting in. What I've been wanting and have thought about developing myself is a universal play/pause control that pauses whatever you happen to be listening to at the moment, whether it be a desktop client like iTunes, Spotify, Rdio, etc, or if it is something running in a web browser like Pandora, Soundcloud, Youtube, etc. This app takes a step towards this in the way it handles iTunes and Spotify at the same time, by controlling whichever app had focus last. I imagine for web browser control a browser extension would necessary. And ideally a plugin architecture would exist to allow 3rd parties to add support for additional apps.
