Apple is not informing me why my podcast is requested and I for the life of me can't see any errors it is a valid RSS/XML feed could someone please advise

http://www.radiobreakout.com.au/podcast?podcast=thebottom

the email I got from iTunes is the following

> Dear podcast owner,

> The following podcast has not been included in the iTunes podcast directory.

> Name: The Bottom :: Radio Breakout Feed URL: http://www.radiobreakout.com.au/podcast?podcast=thebottom

> Submissions may not be included in the directory for a variety of reasons. For more information, please see the podcast technical specification at http://www.apple.com/itunes/podcasts/techspecs.html.

I would be 10x easier if iTunes would tell us what the issue is or have an online validator as we are on Windows and other podcasting apps with no issues.
