Because each user's playlist differs, you cannot find your feed via the standard iTunes store. To listen to your playlist content via iTunes, you have to manually add your RSS feed to it.
To setup your RSS feed in iTunes, you can follow this process:
1. Right-click on your personal RSS link (found on your playlist page), and copy the link.
2. Open iTunes, and click on "Advanced" in the top menu options. Select "Subscribe to Podcast."
3. A "Subscribe to Podcast" popup window should open. Right-click and "Paste" the copied RSS link into the box.
4. Click "OK" and wait while the most recent episode from your podcast downloads to your computer.
