If you want to download these MP3 files and put them on your iPod for later then you need to download and install Real Player. This browser add-on gives you the ability to hover or right click on the player and download the audio as an MP3 file. Click here to download Real Player. Under the main download image is some test "Get the BASIC player". Click this and then save and install. This may not be trivial to achieve, so be careful.
