hmm, well it depends on your group of friends but assuming that not all of them are hardcore underground respecting conscious music listeners like most of us, you are going to have to play some mainstream-ish type music. and you want the girls to start bumpin and grindin for sure.

i cant stress enough though you gotta feel the mood and assess the people there before you play a certain song or type of music. i LOVE reggae, but at my type of parties if i played any of my favorite reggae people would croak. so the songs i mention are catchy, old school enough, mad street cred, , and all the ladies love em.
