Humorous Thought, but Realistic - Invest wisely, choose a Reliable, Appropriate Disc Jockey Service that will give you & your Guests a Night to Remember. Ever been to a wedding where the music was bad and no one was really dancing? You remembered that, didn’t you? Music is a huge part of a Wedding and can really make or break it. DJ’s can be great when you find a good, experienced one. The main thing that makes a good DJ is when they know how to read the crowd and when to play appropriate music, like light music at dinner and more upbeat music when the dance floor opens. Otherwise, your guests will be shaking their heads in confusion and will be disappointed that they won’t have the night of dancing and partying like they thought.
