Pandora versus Genius versus... Zune?

Wired is reporting that Microsoft will be releasing a music recommendation feature on September 16 that outshines Genius, though there is no mention of Pandora in the article. The approach that Microsoft is taking seems to be more robust in that it incorporates the artists, albums, and fans of that song into one recommendation algorithm. Of course, this could all be a marketing-driven smoke and mirrors show--the proof will be in the pudding. I'll eagerly be watching the accuracy ratings of Pandora vs. Apple/Genius vs. Microsoft/Zune in the coming weeks and months. For now, I prefer Pandora.
