Foomatic:A strange cover of Britney's "Toxic" by Yael Naim
aaaaah! I love that cover, it's so tantalizingly dramatic, but subtly so. SO yummy.
Have you heard Nickel Creek's cover? I think they were the first group to really hit up the cover of that song, and they did it with their usual bluegrass finesse and magic.
