I'm wondering if there is any way to have podcasts play in iTunes playlists.  I've just made one right now with some podcasts (along with Giant Bomb's) along with some songs thrown in, as if to add commercial breaks.  But, every time I play a song or podcast first, it will always end up going to a song next after it's done and never again on another podcast.  Anyway I can change this?

You might need to turn shuffle off. It worked for me.  If that does not work, then I do not know what to tell you.
