Meeting DJ tonight to go over wedding songs etc.What else?

I would go over your play and do not play list, as well as any special annoucements you want your dj to make.

I would go over how you want things done (i.e. cocktail hour music, music during dinner, etc) and give your dj the ages of your crowd. Tell them if you want more oldies, or any other kind of music.

Make sure they have all backup equipment and insurance.
