The recent post that mentioned writing and music has prompted me to post this. I recently completed a short story where I used background music to control my mood, and hence the story's mood. I played, again and again and again, the same piece. It was Fjara, by Sólstafir, and Icelandic psychedelic metal band. I highly recommend checking out their video here: Has anyone else done something like this? I am so pleased with the final outcome that I would not hesitate to recommend the experiment.
