On the stations using Streamaudio, like KBPA and KDHT, you don't have to register. Just click, "Decline," and move on. There also used to be ways you could get the link to the stream so you didn't have to use the embedded players. However, you have to do it with Firefox or Netscape; it didn't work with Internet Explorer. I'm not sure what the other Emmis stations use, but there may be a way to listen without registering.
