There's a line on this synth track where Josh Homme sings about having an "addiction to friction." He explained the lyric to The Independent:
"That addiction to friction – what's the synonym for that? Collaboration, sex, the universe. The universe is made out of collision. If everything was perfect and parallel, no one would touch and it wouldn't matter. It's in the collision that sparks the fire that's worth standing next to. Some people call it looking for trouble, but I disagree with that. I'm looking for action, you know?
The universe was made out of imperfection. Perfection is like truth – something to strive for, but not something to expect. Now, with Pro Tools [recording software] you can make perfect music and you know what it sounds like? Boredom. No collisions, no trouble, no spit, no blood, no nothing."
