This is an interesting concept: you log on to this site, enter the name of one of your favorite songs or bands, and the site will begin playing a succession of songs similar to your choice that it thinks you'll dig. It's both cool and a little scary.
The site was created by the Musical Genome Project, a group that anlyzes music by breaking it down into its fundamnetal elements. A staff of trained musicians has listened to some 500,000 tunes and noted their various characteristics, including "repetitive melodic phrasing", "subtle use of vocal harmony" and "minor key tonality", among numerous others. These traits are used to discover similarities between songs and to build playlists that are geared specifically toward your own taste. And--the site is free.

I just tried it. I typed in "Planet Earth", and so far it's played "Nightmares" by AFOS, "Shake it Up" by the Cars, and "Shock the Monkey". Excellent songs that seem to make sense. There's a feature you can click on that tells you why they pick the song they did, and it told me: "based on what you told us so far, we're playing this track because it features electronica influences, minor key tonality, electric guitar riffs, and many other similarities identified in the music genome project." The FAQ is very detailed wrt music theory.
Wonder what you guys think.[?]
