Lately I have been working on some samples for my presentation in Columbus (Drew) and Austin (Scott Belleware). Tonight I came up with a new sample idea. With iTunes 4.2 being one of my favorite applications and one of the only ones, outside of VS.NET, I have open all day, I thought it would be cool to build a transform from the playlist to RSS, based on the songs I have recently played. It isn't a very real world example, unless you are the RIAA :D, but is a good sample on how do convert an existing XML file to RSS. I will post the transform later after I clean it up some more. The web app actually runs decently fast, knowing it has to go through my playlist (3546 songs).
