The wedding I played last night was outside in the cold. I despise playing in the cold for obvious reasons. Shortly after the wedding everyone move inside for the reception. I spoke with the DJ for a little while and mentioned that he had it a little easier as his equipment was inside and unaffected by the cold. He then went on about how much times it takes to prepare the playlist for each client. I told him that us trumpet players prepare too. It is called practice. Didn't hurt his feelings too bad as he did ask for my card for referrals.
