LINQ likes iTunes and they are up in the tree!
Would you like to have your iTunes lists play on the Zune? Avner Aharoni wrote an application in Visual Basic using LINQ to do just this. If you want to view just the LINQ, you can head over to Code @ MSDN.
So why is this possible? Since LINQ can do XML and iTune's database is just XML, it is just a simple query!
