You can enter an iTunes feed directly into the Podcast section of your iTunes library. Each time new content is added to the folder or playlist, the podcast is updated.
Note: You must have the iTunes application installed on your computer in order to subscribe to a folder or playlist.
If the content owner has included an iTunes feed for you to subscribe to, it is found at the top of of a folder or playlist's view page. Note: Only the content creator (you) sees the Publish button. This is used for publishing your feed to the iTunes Store. Learn more.
Subscribe to iTunes Feed
The iTunes button is the fastest way for your viewers to subscribe to a folder or playlist since it automatically launches the iTunes application, copies the feed URL, and sets up the iTunes feed within the Podcasts list in your iTunes Library.
