Fixed.
There were spaces left in the mp3's title. You get a 'bad request' error if the mp3 title isn't one continuous line with no breaks - however...the site's internal player played the show fine. If you used Winamp or another player the way I do - not so much. It's ok now.
Most of his other recent countdown shows have this problem also. I just woke up (damn insomnia), so I question my accuracy at the moment. I can fix them later or he can.
