One week ago there has been an interesting article on the german website Spiegel Online. It describes the work of a team at the university of Vienna that tries to develop a new kind of map as a GUI to manage the database of a large music collections.

Intuitive and really easy.

The webpage of the team can be found here:

There seems to be a online-demo.
