Just for fun: We’re increasingly obsessed with the music in the first trailer for “Wall Street II: Money Never Sleeps.” Less than 15 seconds of research on the Internet reveals that it is “Ricochet,” a song by a band called Shiny Toy Guns. The first line of the song: “Welcome back to where I’m gonna have you.” We’re a little bit late to the game, having missed its previous sampling in Knight Rider and elsewhere, but better late than never. Watch a couple of trailers for Wall Street II over at Deal Journal.
