MP3s being stripped from feeds

Here's an example feed http://rapradar.com/feed/. Whenever this feed contains an mp3 file, once the feed is processed by autoblog, on my site the mp3 file is removed completely. It's as if the feed never had an mp3 file (but im sure it did as its showing up within the feed as an embedded file).

Is there a way to fix this?

Thanks for your help.
