Well we do have some people here that want to use iTunes. But for personal reasons I don't like iTunes.
So I normally use VLC like any sane person would do :) But while all of my co-workers were laughing at me cuz i couldn't join with the music streaming.

There was a program called Airfoil but hey I'm dutch so i really don't want to pay for programs unless necessary. At the VLC forums i stumbled on a post by crzyhanko and he posted some great code you can put in the standard streamchain field of the VLC player:
<ip address of airport express>
It works :D so who is laughing now
