I've always wanted to be a writer that had a playlist to go with my books. I want it more than ever, after reading BuildingMyLife's playlist posts for her WiP "Lighthouse". 1, 2, 3 and 4.
The fact is that while a song might inspire a story, or while I might think a song has a similar theme to one of my stories, I don't have play lists. I can't write and listen to music at the same time. I've tried, but I'm just one of those people that tunes out the sounds around me when I write.
However, I've been thinking of trying to find ways to create playlists for my stories anyway. A kind of "If I could listen to playlists, these songs would have been on it for this book". Or if I ever make a book trailer, I could use those songs as the music for trailer. (Oops, then there's the whole thing about getting rights to use those songs.)
