Remember a while back (or, like, last month, in Lone Ranger) when every single action movie had to involve a train set piece, and you couldn't go near a movie theater without one famous actor punching another on top of some fancy TGV situation? Icona Pop's "Girlfriend" video is like that, except the train is rusty, and instead of punching, there is dancing. Also, you have to assume that Icona Pop actually filmed this on a moving train and not in front of a green screen. Good job, Icona Pop! You are summery and brave.
