I was introduced to this song by one of my closest friend. The name of this sing is who you are by Jessie J. This is song that talks about people that obsess themselves into being perfect and are always finding the most little of erros that only they can see.

I stare at my reflection in the mirror:
"Why am I doing this to myself?"
Losing my mind on a tiny error,
I nearly left the real me on the shelf.
No, no, no, no, no...

The intented effect on this song is imagery when the artist says "I stare at my reflection in the mirror"  i can visualize a girl so insecure staring at herself in the mirror judging herself because she sees imperfections.
