This simple script uses xdotool to control rdio, running as a chrome app.
It's best used for binding to global hotkeys. For example,
I use win-p for play/pause, win-[ for previous, and win-]
for next. And win-o to bring the app to front.
This script assumes we're running rdio as a separate chrome app. It's easier for xdotool to find and interact with the window in this mode.
To install rdio as an application shortcut go to Tools -> 'Create Application Shortcuts...' and follow the prompts.
