I am either hallucinating or have noticed something very weird about the song.
On VH1, MTV, and the radio, the song bursts into drums and electric guitar at the end (when Amy hits the hard chorus and the instruments pick up). It sounds pretty cool and compliments the song quite nicely.
But my.......umm....."acquired mp3" version of the song does not do this. Is there two different versions of the song? On my mp3, she bursts into that part of the song at the end, but no drums or guitar are present. Someone confirm this
