Robby Ingebretsen has created one really awesome Silverlight 3 application which you should definitely see.
This is (as I mentioned) a Silverlight 3 app. You’re welcome to download the source (here) and do with it as you please. It uses the completely awesome Saluse Media Kit to create the playback visualization bars (in conjunction with the must have WriteableBitmapEx
extensions for WriteableBitmap). If you have your own list of 25
albums, it would be easy to reuse this. It’s driven by an XML file.
