Adobe Connect MP3 Extension XML URL Format

Do I need to explicitly name the .mp3 file in the URL?

In the XML file that comes with the extension the URL contains a direct link to the .mp3 file.

<songs>

      <song url="http://my.adobe.acrobat.com/gloss/output/gloss.mp3" track="Gloss Finish" artist="" />

</songs>

In my case, however, I wanted to take advantage of the shared content folder offered by the online adobe backend. The I uploaded my song to the shared content folder, and adobe connect auto-generated a URL for the file that does not contain the file name or the file extension.  I tried it in the MP3 Player XML file and I can see the track title, but the URL is not working.

<songs>

          <song url="https://changeyourenergy.adobeconnect.com/p5pzke7k091/" track="BackgroundMusic-PastelSmiles" artist="" />

</songs>

Do I really need to serve this file separately?
