Ive heard that there is problems listening through Windows 7 we are working on a workaround on that

As for Itunes you should be able to listen through Itunes by clicking on the icons in our "Tune In" Block on the left hand menu just below the song requester, i suggest the Winamp sign or Real Player icons as they are set for default mp3 playback whilst the Windows icon is set for Windows Media only!
Let me know if that helps or if you need any more help
