Why is iTunes not picking up my podcast?

Q: Why is iTunes not picking up my podcast?

Feedburner tells me in PodMedic that enclosures are not being created because files are not recognised as audio/mpeg. I asked Hostmonster about this and they ran a test, and concluded the opposite: that the server is in fact returning the appropriate status.

My website is http://kidyounotpodcast.com

My feed is http://feeds.feedburner.com/kidyounotpodcast/rss

My email is kidyounotpodcast@gmail.com

Feedburner PodMedic says:

Content Type reported: text/html; charset=UTF-8
Media enclosure not created because: The content type returned from your host server was a text type, not a binary media type. Podcast content should always return a binary media type, such as audio/mpeg for audio, or video/mpeg for video.

Hostmonster says:

curl is a tool that allows me to send requests to the server as if I were a browser, and see what goes on behind the scenes. The -IL uses the HEAD request to gather only the headers (and follow redirects). The curl output is in the first block. You can see that the Content-Type is being returned as audio/mpeg, it’s returning the appropriate status, and the correct content-length. Everything looks good there.

Thank you for your help!
