First try clicking this pcast link. This may or may not work (if it brings you to iTunes, it should have worked), depending on your particular set up. If not, try the following…
For iTunes, first right click (control click on mac) that mp3 RSS link above (or find it on the right side of the main page). Then go to iTunes, click on “Advanced” then “Subscribe to Podcast”. Paste (control-V or option V on macs) the URL that you just copied into the window that pops up. Click ‘OK’.
That’s it. You’ll be taken to your podcast directory in iTunes. You can click “Settings” to set how often it checks for new songs, how many to keep at a time, etc.
Note that this only works with versions of iTunes after 4.9.
