The Nexus music demo currently involves a manual setup step, running the script constructNexusPeers.js, which sets up the machinery for the different components of the music demo to interact. The Co-occurrence engine was developed to eliminate this sort of configuration work by declaratively specifying and dynamically constructing component interactions (GPII-2670).

The music demo should be updated to use the Co-occurrence engine. This is a good learning exercise to become more familiar with the capabilities of the Nexus, and will make the demo easier to run.
