Well, I got a lot of inspiration from Buffy obviously. Ghosts has this whole resonance to Buffy. I thought of some lavish scores, and some excitement and energy and a lot of mystery and mysticism, so I just used that as inspiration.

With one of the themes, I was running hard on ideas. I was watching Attack of the Clones, and thought, "ah, good old John Williams, good bit of inspiration there, got a nice little brass line from that".
