If you're more of a Star Trek fan, you can listen to 24 exhilarating hours of the Enterprise-D not doing anything:
You can even listen to the ambient whirring of the Satellite of Love from Mystery Science Theater 3000 for six hours, and not a single second of which is funny:

YouTube users have supplied us all with the soundtrack to closing our eyes and pretending all of our petty earthly problems have been replaced with the constant anxiety of maybe getting sucked out into the frozen black of space after a hull breach. The dullness of these videos has a lulling effect that makes it easy to slip into a sci-fi-induced techno-coma of mindless dedication to whatever task you have at hand. No wonder the Empire was able to build 3/4 of a brand-new Death Star within four years. Once they kicked on the ambient hum, everyone immediately got to work, rebuilding a thing so dangerous they forgot it had history of being blown up.
