My god, it sounds divine! She should record an acoutic version of this song and release it as an iTunes bonus or something. I like this version so much more than the heavy Freemasons production. Hmmm, come to think of it, i liked the acoustic version of Heartbreak better than the Freemasons production too... Maybe her 5th album should be acoustic-electronica. Like Madonna's American Life album.
Anyway, you can watch the performance here, if you've missed it
(many thanks to Paul)
