At our destination wedding, we used a harpist only for ambiance music before the ceremony, during the ceremony, and after the cermony. We then had a DJ for the reception. At our "home" reception, in Saginaw, we set up a playlist of our favorite songs on our ipod and connected it to the reception house's stereo system. It was perfect--we only heard exactly what we wanted to hear!
