To cut a long story short: I listen to music podcasts a lot and unfortunately a lot of record labels syndicate their content via Apple's iTunes network. Apple seem to go out of their way to make finding the actual original source podcast feed a complete nuisance to find and I absolutely detest iTunes so I wrote this to grab it for me. Now that lovely rant is over, you can use it too..
Install the bookmarklet
Drag the following link to your browser's bookmarks bar: itunes-to-rss
Then visit an appropriate iTunes podcast page, e.g: The Critical Music podcast.
Click the bookmarklet while on the page to reveal the true RSS podcast URL/content feed.
Rejoice in the fact you no longer have to load up iTunes. For the time being anyway.
The project can be found on Github here: uncover-itunes-rss-bookmarklet.
