I mainly spin hip hop and r&b, with a little house and club on the side. To me hip hop and r&b are the harddest, I still find tracks that are a pain to mix and make sound good. House, club, techno and dance are easy for me to mix. The long intros give you so much room to work in, unlike hip hop and r&b, plus you don't have to work around vocals, so for me hip hop and r&b makes me work a little harder to spin a perfect set.
