I like to listen to music when I'm writing. A lot of people do--there are people who find music or any other kind of noise distracting, but if I'm listening to the right music at the right time I find my ability to write increases a thousandfold, and "thousandfold" is a pretty good factor of increase. So for my writing projects I like to come up with playlists that reflect not necessarily the mood of the story, but the mood I want to be in when I'm writing the story. So my writing playlists are usually some combination of "songs that I like" and "songs that I like that are also sort of thematically appropriate."
I have posted the playlist I used when I wrote Pay Me, Bug!, and the playlist I use when I write The Points Between. I have yet, however, to post a playlist for Curveball. It's still a work in progress.
But I do want to talk about one song. It's a very important song that I play every time I sit down to write about CB. If you know me, you'd be surprised by the song. It's not what you'd expect.
