I am familiar with podcasting. I subscribe to a Jazzercise podcast through my iTunes account for when I travel. I tried to figure out how to get one of these embedded into my blog, but I don't think you can from iTunes...at least I couldn't figure it out!
I was successful at creating an account and setting up a playlist at Last.fm The results have been added as a page element to my blog on the right-hand side. I hope you check out some of my favorite songs. It's a pretty eclectic mix, if I say so myself! Enjoy!
