> Sometimes there is. Sometimes it's just made up shit with no real backing in the same way a lot of stories told in comedy routines are. Not all of it is genuine expression.

I don't necessarily agree. Read the lyrics to the "irony is a dead scene" EP by the Dillinger Escape Plan and Mike Patton. It's nonsense. Still genuine expression.

Most Carpenter Brut songs don't even have lyrics and there is endless expression there. I know that I consume music in a very different way than most people, and that's probably why I have such a strong opinion here.
