I was wondering who the bonus tracks were about, this is what I think:

Superman:Quite obviously this one's for her dad..

Ours: This is a bit trickier but I think it's about Toby Hemingway, her co-star in 'Mine'. Why? Because she sings 'I 爱情 the gap between your teeth' and 'any snide remarks from my father about your tattoos' and his 'bleach blond hair', all of which describes Toby. Finally, when she's 唱歌 'right now you're mine',she lays a special emphasis on 'mine'. We all know she dedicated mine to him.

If This Was A Movie:I have no clue. Enlighten me, would you?
