I LOVE THIS SONG! One of my favorites off the new album

Same here - one of my favorites :)

yeah it has a realy cool sound to it, but so so alot of there songs. i love this band

This song strikes me as strange because of the possible implications of the lyrics.

When I saw you walking by, I could not believe my eyes.
Underneath the city lights, reflecting all your curves just right.
Can I have your attention for a moment? I just need to say something.
If you've got the time then I've got the reason for the sin.
If you've got the time then I've got the reason for the sin.

The first verse seems like a proposition to a curvy woman in the city. That makes me think prostitute. Well, she could also just be an acquaintance he happens to see in the city. Clubbing maybe? Whatever the case may be, he's motivated to sin with her.

Have you been looking out? Have you been watching my back?
My patience is running out and I can't seem to stay on the right track.

He talks about his patience running out and being unable to stay on the right track. So, it sounds like he's repeating some sort of sin, probably sexual if my interpretation of the first verse is accurate at all. He also asks if "you" [Who I assume to be the woman since the song is modeled like a one sided conversation] is watching his back and looking out. It sounds like discovery would get him into trouble.

Your wanting eyes keep me coming back for more and more each time.
Let's get this right cause there is no second chance after tonight.
No chance after tonight.

This stanza has a certain finality to it. He wants to get something right because the chance to do so won't be presented later. This makes me think he wants to leave. It seems like her eyes will still be there, so he must be the one motivated to change the situation. Maybe he wants to make amends for their sins.

I know you've got it in you, won't you let it out?
Dig a little deeper and I know you'll find strength inside.
If we can be the ones to hold on, to stay strong.
Then maybe we can make a difference in somebody's life.
In somebody...

This sounds like he's pleading with her to find some sort of inner strength. Maybe she's grown dependent upon their sin. It might be an addiction of some sort if not sexual, though the "reflecting all your curves" line would seem out of place if that were the case. It sounds like he wants both of them to decide to walk away from their sin and stay strong so they could possibly make a difference in the lives of others. Maybe the others are future love interests. If their sin is a sexual affair, then that would make sense. They wouldn't be able to have healthy relationships with others if they continued in their sin.

I won't be part of the riot.
I won't be part of the revolution.
They think they are keeping us quiet.
We aren't the problem.
But we are the solution.

Sorry, I've got nothing here. I don't really get this stanza. Is "they" the members of the riot/revolution? What riot is he talking about? And, if he and she are part of the solution instead of the problem, what is the problem?
