Audioscrobbler continues to amaze me. Profiling your listening tastes and creating a personal stream from that profile is cool, sure, but you soon crave a visualization of the network of relationships that your taste is at the center of. Enter the TouchGraph app for Audioscrobbler. It is pretty basic, plotting relationship maps of artists based on the same algorithm that computes your musical “neighbors.” But you could easily see a more generic app that could take your Audioscrobbler XML feed and continually morph the map (like the Eternal Egypt screensaver, blogged yesterday, does). Clicking on any node might take you directly to a stream of that artist (or the iTunes store). Or maybe there’s an integration point with the attractive (and more info-dense) LivePlasma.

My current thought-exercise, though, is what to do with the links between the music nodes. How could you sonify them? What does the musical connection between, say, Johnny Cash and Cake sound like?
