One of my favourite songs they've ever done...

The man in the song has fallen for a "bad girl" and in the first verse he's determined to prove himself.

"Don't you underestimate my dirty mind My dirty talk, my dirty thoughts Can't you feel it in the way my body moves"

Only problem is, the man falls for the girl. He knows it's no good, that he is better than this but he can't help himself he can't resist her: "Who am I kidding, you're my one and only vice"

She sets him free, he can't let go: "Just because we're over doesn't mean that I'm free Because I come right back to you"

There's just two things that confuse me, the last lines about the photo in black and white, has it anything to do with the saying "take a picture it will last longer"? Black&white because of the dramatic/realistic approach (i.e clear cut no grey area?)

And the part where he talks about her pretending not be more than the distraction (second verse 3rd last line) is this the girl in question being a distraction from his own dismal pain/life. Or is it another girl he's using to distract himself from the bad girl in the beginning?

An error occured.
