I've started listening to "ambient noise" soundtracks while browsing the Boards. It helps to fill the "must-do-several-things-at-once-to-feel-productive" quirk I have.
After watching all 7 seasons of Star Trek: The Next Generation, I had gotten pretty used to the Enterprise-D's engine humming. Now I get to feel like I'm on the Enterprise while I'm discussing BIONICLE 2015.
Who else listens to ambient noise?
