A combination of music for all of my novels. I make a soundtrack for each one, and try to add some variety, although usually one artist takes over, at least in the beginning stages. 3 Doors Down and Daughtry if I had to narrow down artists for my current WIP, but I have 19 other artists on the current temporary playlist. Dido and music from the first Buffy soundtrack made the top of my AFTRLYF soundtrack. Right now Five For Fighting and Christina Aguilera rule my other WIP, but except for one of each, most of those songs are competing with songs from other artists for the same place in the plot, so that one is very tentative.
