Wow! Amazing hope he leaks this song in HQ, it surely sounds great! IMO it sounds like her but we've had many leaks that sounded like her and wasnt her.
it's like we have a bunch of demos from the "Britney", "In The Zone", and "Blackout" era yet we have NOTHING from the "Circus" era. Well we have Amnesia, Trouble, Rock Boy and Quicksand but those don't count!!!!
