Music Genome Project.

I just learned about the Music Genome Project and its site which uses a complex set of over 400 metrics to select online radio programs for the listener. REALLY INTERESTING! I typed in as a starting genre "Led Zeppelin", and after playing "You've got to groove", they then played a Grand Funk song I'd never heard of - and I was surprised at some of the similarities. This is very clever application, and fun too! Check it out.
