I would say that my Favourite Songs by her are-
Naked, Forgotten, Too Much to Ask, Fall to Pieces, I'm With You, Mobile, Nobody's Home, Forgotten [Which really makes you wanna Punch someone in the face, despite the fact i'm a Pacifist Haha] & Together...Oh & Freak Out x) Which is just Awesome!!
...Yeahhh, I like all of her songs x) Hahaa.
