Okay, so this might sound like a really dumb or obvious question, but I honestly know nothing about djs. Tonight, I went and saw two different djs play at two different weddings. What am I looking for in a dj? What makes one dj better than the other? What makes a good dj in general? Everyone tells me that the dj will make or break the reception, but honestly I feel like all they do is annouce things and play music, so how can they mess it up? I obviously don't get out alot (haha).
