I just finished the first chapter of my first novel and must say I'm quite excited. However, as I was writing I noticed that I was naming real musical artists, movie titles, and books. I remember reading a review about a Tom Clancy book in which he was criticised for using a real town and place as the setting for a terrorist attack. Was wondering if there are any unwritten rules for this? Am I going to somehow piss off Metallica if I name drop? Will no where-ville, Alabama get angry at me if their town is the setting for my crime novel? What thoughts/ knowledge do you guys have on this? Thanks.
