App to listen to streams in .wma format?

[Hyposprayer]

I work for a church doing computer-related things. However, my father and I also help to operate an internet radio station for the church that streams a live broadcast of our Saturday church services. When opening a link beginning with mms, Android acts like I'm sending a text message and apparently doesn't have a proper player to bring it up in. On PCs it shows a video feed on Windows Media Player. I don't care about the video as long as I can hear the audio. I've searched around and can't seem to get any clear answers on how I can get this done. I can guarantee you that it's not already on some list because it really isn't horribly popular yet.

So does anyone know of an app (free) that will play a .wma stream and allows you to add custom urls?
