Check out this ridiculously good version of Britney Spears' Toxic by Yael Naim. If you've been living under a rock since January, Yael Naim is the artist who did New Soul, the song used for the macbook air commercials. I don't really have an incredibly strong opinion one way or the other about Britney, but I always liked her version of Toxic. That being said, I definitely think Yael Naim's version is much better.
