If you want to listen to something both beautiful and creepy, click on this. It's web radio developed by the Music Genome Project, and the way it works is this:
1) You type in a band or song that you like.
2) The website generates a (sometimes funny) description of the musician/music type listed.
3) And then it starts playing music in the same style. You, the listener/guinea pig get to "thumbs up" or "thumbs down" the different selections.
I'm using it to talk about audience adaptation next week--it's AI and Rhetoric working together. Who knew robots could be so rhetorical? Dr. Who, maybe. And Dr. Baltar. And that guy from the Cantina who doesn't like Luke. And House, of course, because he knows Everything.
