Pavement - Zurich Is Stained Lyrics

I can't sing it strong enough:
That kind of strength I just don't have.
If you watch the lights change please
Don't hold them hanging.

You think it's easy but you're wrong
I'm not 1/2 of the problem
Zurich is stained and it's not my fault
Just hold me back or let me run.

What does it mean a mistake or two?
If it's the kind of mistake no one can trace
To the fountain where we sold it
And held them hanging.
