musicnetwork is a set of scripts to visualize the social connections between the bands you listen to and the bands they themselves associate with. It connects to iTunes to get a list of every artist in your library, then visits each artist's Myspace page to see who they count as a top friend.

Here's a bit of the graph I made from my library:

By default, an artist is shown in the graph if it has at least four incoming connections. Artists in your library are drawn as folders while the other artists are drawn as ovals. The colors don't mean anything, they just make it easier to follow the lines.

Usage:

ruby network.rb
ruby graph.rb

Requirements:

• ruby-graphviz and Graphviz itself to draw the graph
• rb-applescript to get the artists from iTunes
• nokogiri to scrape the Myspace pages
