Writing is very similar. It can hard to write something somber while listening to something upbeat, or write something upbeat while listening to something somber. And for me, I can never write scenes with dialogue while also listening to music with lyrics. As music can often change someones mood, I use it to get into the right mode, or mood, for writing certain scenes.
There are several songs and pieces of music that I have been using lately while writing The One You Feed, and I'll be posting them periodically. Here is one by Hanz Zimmer from the film Inception. I used it for my more somber moments.
Any other writers out there? What pieces of music do you use?
