I ALWAYS listen to music while I work on a project. The type of music I listen to changes though, mostly depending on the mood I'm in or the mood I'm wanting to convey in my story.
I listen to a variety of music ranging from screamo/heavy metal to classical. Recently, I've been listening to classical and chill step.
A few of my favorite artists are Rise Against, The Word Alive, Crown the Empire, Crywolf, Koven, Josh A., Mattia Cupelli, and Ludovico Einaudi.
