[Bob Lentil]

I did a little bit of research and the consensus seems to be that this sort of problem is most commonly caused by the web server being set to the incorrect MIME type.

Here's some stolen generic info about MIME: MIME means Multipurpose Internet Mail Extensions, and refers to an official Internet standard that specifies how messages must be formatted so that they can be exchanged between different email systems. MIME is a very flexible format, permitting one to include virtually any type of file or document in an email message. Specifically, MIME messages can contain text, images, audio, video, or other application-specific data.

Internet Explorer (before XP service pack 2) uses the file extension to determine what to use to play a media file, so it's not affected. Firefox, however, uses the web server's MIME type setting to determine what to do with the file. I messed around with Firefox's MIME settings a little bit and couldn't get it to work at AM, but when I went to another similar internet radio station Firefox did work. Therefore, I'm guessing this is an AM web server problem as opposed to a Firefox problem. Also, according to what I've read, anybody using IE and Windows XP with service pack 2 installed should be having the same problems.
