Music To Write Books to

The bulk of my writing is done at night. There's a calmness to having dark blanket the world; no one needs me for anything, work is most definitely over, I can exist, just exist, in peace. It doesn't last long, the peace, because my brain starts asking questions, questions like: why aren't my fingers typing, or why am I wasting perfectly good writing time? It always wins in the end -- no rest for the wicked, as they say. But with my digits in motion and half an idea in mind, what do I drown the uneasy silence out with? Music, of course.
