I love writing to music. I carefully curate my playlists for each book, for each mood. For example, I’m working on a space opera right now, and so I’ve selected several bits of electronica for intense scenes, for ambient scenes and sad scenes. I keep it carefully compartmentalized for emotional content. There’s no point in getting super amped-up if I’m supposed to be writing a quiet confessional. Likewise, sad piano music wouldn’t get me through a laser-strewn dogfight.
