There's an incredible amount of functionality that can be provided by the Views module, especially when it is combined with intelligent use of Node Reference fields. When you relate your site's nodes with Node Reference fields, these relationships can be easily leveraged to create some very useful views.
I'm going to build a view for a sample music site. In the site, I have 3 related content types for "Band" nodes ("Black Eyed Peas", "Linkin Park", etc...), "Album" nodes ("Back in Black", "Bat Out of Hell", etc...), and "Events" (concerts, television appearances, etc...)
