Thanks for de info, Jimmyjimmy, but, as far as I know, there's a demo for "Wash All Over Me" known as "Demo 4" and the time is 4:17
All the people I know that is not a Madonna fan love this song and all of them say the same thing about it as soon as she starts singing "Hey! It's Madonna". With most of the tracks of "MDNA" they say "Who sings that song?" and when you say "Madonna" they say "Ah, ok... I didn't recognize her voice". I think that the good thing about "Beautiful killer" is that. You hear Madonna all the time. I'm not saying that the rest of the songs are bad but I miss her real voice most of the time. I think that without so much distortion on her voice they could be much better.
