The MVC Music Store is a sample application built on ASP.NET MVC Framework 2. It includes the source code and a tutorial explaining the steps to build it. This is a great tutorial if you want to get started on ASP.NET MVC 2. When I looked at the documentation, I noticed that the data used by the application is very familiar. Jon Galloway, the author, mentioned on this post that the MVC Music Store data is based on the Chinook Database. The Chinook Database was built using my iTunes library as sample data, and that is why I recognized some particular artists and albums: a mix of rock, heavy metal, classical music and Brazilian music.
As to the Chinook Database I have a list of improvements to be done and need to get sometime to work on a new release. I am also thinking about adding support to document-oriented databases such as Raven DB and MongoDB.
