Our DJ didn't take note of any of the requests we made prior to just before the event. His setup includes two i-pods. He doesn't crossfade well, and is not sensitive to the guests needs. We requested starting out with older music to get our older guests on the floor before they left earlier in the evening, but he jumped ahead to music that they could not relate to at all. Not recommended.
He took beautiful and professional pre-wedding photos of us. Everyone was so impressed with how beautifully they turned out. He's very nice and professional, as well.
