iTunes help!!! Trying to stream to Xbox 360

[wdcspurs]

I am trying to figure out how to play my iTunes library, including playlists on my Xbox 360. They are on the same Network. I know there is an app called Airmusic that will play music off of my phone to another device, but I am looking for a way to stream iTunes music from my pc to the Xbox. I wasn't sure if Airmusic would do that. My other thought was itunesmatch. I am probably going to sign up for that, and then at that point, can I use AirMusic app to stream the itunesmatch content? Basically I am trying to keep most music off of my phone, which is where iTunes match comes into play. And also a way to stream my iTunes library, including playlists to my Xbox, possibly using my iPhone as a remote. Please help. New to the iPhone.
