Ok...The first time I heard that song I hated it!
I really did...I used to say what's wrong with her did she lose her mind to sing this?!!
But later...I LOVED IT!
I just guess the music arrangement is weird, that's why I didn't like it in the beggining...
Anyway here is what I think you should do...
First listen to the original track then listen to it from a concert
Concert begins at (46:09)
