I for one welcome our robot overlords.

Hah. Yeah, I thought the same thing. Like Tennessee Jed.

That might be true, about the lyrical content, however the vast majority of music that I like lacks vocals. I have discovered (or, i suppose, Pandora has shown me) many artists that I really like that I had never heard of before. Also, I've been chatting with the creators through email a little, and they are working on a better system of rating. "Thumbs up" and "Thumbs down" just doesn't cut it, so they're going to give users the option of selecting the particular aspects or qualities of the song that they liked or disliked.

I don't know if the Music Genome Project includes information like the instruments used, or the musicians that appear in the recording. If a Movie Genome Project were to be created, these types of things (Actors or Actresses, year, genre) along with perhaps hundreds of other characteristics (martial arts fight scenes, plot twists, midgets) could be associated to a movie and work wonders when trying to link together movies.

Heck, that might be the $1,000,000 answer...
