post on the Music Machinery blog describes how Six Degrees of Black Sabbath works.
- Hey! You didn't know that Rick Wakeman played backing harpsichord on Black Sabbath's Sabbra Cadabra. WTF?

- What do you mean by 'Six Degrees'? Six degrees refers to the idea that everyone is at most
six steps away from any other person on Earth, so that a chain of, "a friend of a friend" statements can be made to
connect any two people in six steps or fewer. This is clearly not true in the music world - it is quite easy to find
longer paths between artists. But I use the term 'Six Degrees' to refer to the overall connectedness of the music world.
- What is the average path length? Around 7
- What is the longest path? It is a secret. People have found paths that are longer than 30.

- What is The Echo Nest? The Echo Nest is a music intelligence
company founded by Tristan Jehan and Brian Whitman, who met at the MIT Media Lab while they were both getting their PhDs
in music understanding and synthesis research. The company has since grown to a small but insane team of developers,
designers, musicians and business people all housed in a cozy office in Davis Square, Somerville, MA, USA. We grow an
intelligence platform that automatically reads about and listens to the entire world of music for developers to build
search, personalization and interactive music applications.

4 step path are stronger.

- Why is this app so ugly? Because an engineer designed it. If you have design skills and would like to
make it look better let me know. I'll gladly give you credit with a link in the footer of the app.

- Why did you pick the name 'Six degrees of Black Sabbath' I knew that if the name was 'Six Degrees of
X' and X was a well-known music artist, people would 'get it' right away. The most connected artist is Pigface - but they
are not well known. Black Sabbath is pretty well connected and quite well known and so I chose them for this great honor.
