misheard lyrics

Fall Out Boy's Pete Wentz apparently penned the following lyrics to express his frustration with blind followers of the Emo trend trying to 'out-Emo' each other:

I am an arms dealer.
Fitting you with weapons in the form of words
And don't really care, which side wins
As long as the room keeps singing
That's just the business I'm in

This ain't a scene, it's a god damn arms race
This ain't a scene, it's a god damn arms race
This ain't a scene, it's a god damn arms race
I'm not a shoulder to cry on, but I digress

Now that actually makes a little sense. Unlike the lyrics I've been mistakenly singing along to:

This ain't a city, it's a god damn horse race.

Which really didn't make any sense at all. 'Rat race' might have been okay, but 'horse race'? Hmmm.

Anyone else been singing the wrong words?
