Why not a little bit of everything???
Mix it up ..... do a few songs at a time of a specific genre ...then a few of the next genre and so on ...
There is no reason you can't play every type of music you two like .... and frankly throw in some stuff neither of you may like but that your guests might if you want people to dance ....
If it's just background music it should still be fine ...at a low enough volume anything can be acceptable :)
Why dont you both pick a specified # of your fave songs ...then work together to come up with some music that other guests may enjoy ..... could be a fun project!!
