Yeah it was 2006 and that was how you got the MP3 files onto your iPod Nano. This was back when “mobile internet” consisted of “m.website.com” links that loaded a page without a style sheet at dial-up speeds that was designed to be navigated with a D-pad.
Sure, but you did you download them, listen to them and then delete them, or did you keep them around for archival purposes? Because it's rather untypical to re-listen to a podcast episode many times, which you might do with music.
