*Most of the audio is mp3 but some is real player media.  The mp3's should open in Media Player and begin to stream without having to download the entire file.  If it does not you can go into the media player's settings (open Windows Media Player & then go to Tools then Options).  Now click on the File Types tab & click on the box next to MP3 Audio File to place a check mark.  The box should now have a check mark with a solid white background - it should not be partially gray.  Now click on OK.  Now the audio should begin to stream.
