Does this song describe Rosalie and her feelings towards Bella?

I came across this video on YouTube, two things popped out at me when I watched it;
1) The song, because I loved it xD and because it seemed to describe Rosalie's feelings towards Bella, an intruder coming into her life and her family's secrets merely perfectly...

2) The song was lebih personal for me than I thought at first (But this is not the point of this discussion...)

I noticed that the maker of this video put a background story behind the video; Rosalie having feelings for Edward which would explain her deep resentment of Bella when first meeting each other.
But I honestly think that this newly made plot wouldn't be necessary considering its connection with Rosalie's character, and that this song (From listening to the tone, lyrics, and indicated story of the song) can still actually portray Rosalie's views/ideas and thoughts of Bella pretty damn well.
But I wanted to check others opinions' first...


So, what do anda guys think? =/
