Podcast submitting problem...

I can confirm that the podcast at the URL you submitted isn't in the Store. Did you also submit the other URLs? - obviously if you didn't they won't be in the Store (the top one isn't).

However, from a quick listen to the first URL it would appear that the podcast contains commercially issued music recordings. Use of these without the written permission of the artists and the recording company is a breach of both copyright and the Terms of Service, and will get you rejected. You may have been sent a rejection email which failed to arrive or was spam-trapped. It wouldn't have given a reason for rejection anyway.
