Questions for Writers #4

Last week, I asked whether you like it noisy or quiet when you write. Many of you said you listen to some sort of music. So, here's the next question:

Do you have a playlist for your books? How many songs are on it? Do they fit the story? Or are they songs you enjoyed while writing? Do you post the playlist somewhere?

I do have a playlist for my books. Sometimes it's only one or two songs, and other times it's many more. Mostly, they are songs I think fit the characters or the story line, but sometimes it's just a song that I think these characters would like.
