This is a quite new way of obtaining interesting material for our classes.
Definition by BBC:
"Podcasting lets you automatically receive the latest episode of your chosen programme as soon as it's available. You need to "subscribe" to receive a podcast, rather like you might subscribe to a magazine and get it delivered each week. An important difference is that all of the BBC's podcasts are free, and you can stop receiving the files at any time".

Actually, you don't even have to subscribe... you can download any mp3 file just by a right click on your mouse...and you will have the files on your computer for your own practise or for that of your students...
Try it, it's worth...
