I'd not heard it before, living in blissful ignorance until today when Samsung shoved it under my nose. Can't comment on the other covers on the soundtrack, of course, never having knowingly heard them, and I am generally open minded about covers. But this one is just a SPECIAL song for me.
In my mind, a more perfect pop song was never made. Now murdered by Rufus Wainwright, aided and abetted by Samsung. Shame, I rather liked their phones.
