Set Global Shortcuts for your Music Player

I was looking for a way to turn on and off Internet Radio while in applications that were running in fullscreen. I think I mentioned that I’m playing Team Fortress 2 at the moment with a few Buddies of mine. We use Teamspeak to communicate while playing. It happens that I’m the only one in Teamspeak which is why I start Internet Radio and leave it running in the background while playing alone.
