No doubt you will want to have some input with your DJ about your music choices for your day. The featured dances (First Dance, Bride/Father Dance, etc are covered under my Wedding Reception Planning Worksheet. I like to understand what type of music the couple really likes. This way, I will know what tastes they have, but it also leaves options open for the DJ to “read” the crowd, take requests, and generally keep the party moving along. I have had brides that have submitted over 100 songs to be played at a reception. This is not feasible- the math doesn’t work. For example: A four-hour reception: Arrival and dinner will last approximately 90 minutes. With time out for toasts, featured dances, etc, your typical 4-hour reception will have about two good hours of dancing (maybe two and a half). The average song length is 3.5 minutes, working out to about 17 songs per hour. This equals about 35-45 songs per reception.
