Its a Tourist Map for Music
http://www.music-map.com/
Its a simple page that allows you to type an artist name or a band name in the box. When you activate the search it explodes into a graphical interface that lists all similar artists.

I did BB King
It listed about 40 artists similar to BB King.
With my choice in the center, the listed artists float around BB King until they get placement. The artists closest to BB King are the ones Most similar and as you move away from the center they become Less similar.

You can click those names and it redefines the map around your selection.
On the side panel it reads"
"People who like B.B. King might also like these artists.

The closer two names are, the greater the probability people will like both artists.

Click on any name to travel along."

Here is a map for 'The Cars' that it shortens to just "Cars"
