I'll be realistic and choose themes that I can imagine actually happening. It's more frightening this way.
Man of Steel or any super hero theme (please Stern, no more)
Harry Potter or any kiddy adventure theme (please JJP)
Led Zeppelin or any long-haired rock band theme (Stern, ...please)
And yes I'm quite aware that some of you are fans of this tired stuff.
Oh, and I really don't like videogame themes, those are the worst, please no Angry Birds.
