Snarfing Audio

[David Walker]

Ok, this is going to come as a really odd request i think.

So I was listening to streaming media the other day, and started 
wondering if I could download said music.   Sadly enough, I couldn't.  
So I started to wonder is there some program that would listen to what 
traffic is being sent to the sound card, then have it dumped into a file?

EG:

Media -> driver -> soundcard -> speakers

Media -> driver -> listening program -> soundcard -> speakers
