Interrational Weddings

I am 3 1/2 months away from my interrational wedding and so far everything has been going great with the planning, except for the music selections. I am a white female from upstate New York and my fiance is black from Brooklyn, so you can imagine the diverse group we will be having at our wedding. My fiance and I really like music you can dance to, mainly R&B and HipHop, but I have some country and rock -n- roll fans coming. Any suggestions for some good music would be a great help.
