I'll cover some of my favourite moments in the prequels: TPM: I love the little trumpet fanfare playing in the background when Palpatine says to Padme, "Together, we will bring peace and prosperity to the Republic." It's those two things together that I get a kick out of. It's hilarious. AOTC: I love the soprano heard when Dooku meets Palpatine at the end. It sounds like a siren -- underscoring the seductive pull of the Dark Side. ROTS: Although this is quite a bombastic moment, I love the way the brass section finishes off The Force Theme as the scene cuts from Obi Wan flying to Utapau to Anakin having his second vision of Padme. It really connotes the idea of the epic, heroic, brotherly love between Anakin and Obi Wan coming to an end (which makes perfect sense -- Anakin and Obi Wan never talk as friends again).
