I got this for Christmas.  I love NPR podcasts, and have figured out how to put them on my Sansa, but maybe not in the best way.  How are others putting podcasts on their Sansa?  How are others putting their podcasts on so that they don’t play under “play all” music files.  Also, my NPR files are tagged in different ways, so there is not one simple solution that I have figured out.  There was a reference on the boards to use MediaMonkey - there are 2 versions - one that costs and a free version.  Which one is needed if that is the only option?  Thanks!!
