because it's a wedding, and a wedding means inclusivity. And that means tracks that stand at least a chance of being recognised by a few people. Funk and soul aren't mainstream in the first place, and apart from Bob Marley, most reggae isn't either. At a wedding you want cheers going up and girls dragging their partners onto the dancefloor when you put a tune on, not a bunch of specialists nodding sagely at the bar.
This is coming from someone who went to a family friend's wedding at 15 and spent most of the night haranguing the dj to play "Trans Europe Express", so bear with me...
I suppose your right in some respects, I've DJ'd weddings and It always drives me nuts that I could slap on the funkiest mind blowing tune that no one had ever heard of, but there would always be someone who would ask if I had anything they could dance to? or Do you have any James Brown? I don't get it? Isn't good music good music?
