I know what you mean but DJ's have to be like that after all they are human? Maybe they are reading a shoutout to make sure it is suitable, getting asked something by a member of their family, checking to see if their pc is running right. Haven't you had that when you are having a conversation with a friend you start going emmmm, ummmm because you stuck with what to say? Well DJ's are really doing that cause we don't exactly have a script to run by. :p
