Fun with Algorithms

I continue my torture of Pandora Radio, my current project trying to get it to make a station that is based on vocal similarities between certain songs I like by artists as disparate as Bjork, Loreena McKennitt, and Nightwish. Since I don't think the similarity that I hear between these songs is one that categories songs by, this may get interesting. It really has a hard time coping with eclectic.

Edit: Apparently what I get with this mix, pre-pruning, is a LOT of techno. And the only techno that went into it was The Diva Dance from The Fifth Element. Lets see what happens when I'm Heavy handed with the "thumbs down"s
