recording sound from a web browser

I use audacity v 2.0.6 and downloaded the .exe

I have been trying to record a song of of Google chrome, but audacity wont record the sound. It records only the sound from my skull candy slayer headset, and nothing else.

How do i record a song off of google chrome?
