Cover art for Simple Design lyrics by Breaking Benjamin

I'm sorry, are y'all on crack?? This song is about commitment in a relationship. Need I elaborate?

I live a chemical life I’m on a mission to try You went insane for the day I'll have to shove it away My only option is gone Smile as they break and they fall You want a simpler life You can’t erase what was mine

He's using her, just like he's using all the other women in his life. She learned of his promiscuity, and went ballistic. Still, he wants her.

You must be out of your mind This was a simple design You fuck it up every time How could you leave me behind?

Simple design?? Yeah, f*ck with anyone you want, that's pretty simple, isn't it? But she won't have that; she wants commitment.

It’s all right, it’s all right cause I know what you want but you’ll just have to wait if I had it to give I would give it away I'm livin' it up while I’m fallin' from grace there’s no way, there’s no way that I’m running away

He knows she wants him all to herself (is that too much to ask in a relationship?!) but he can't/won't. He's too busy 'living it up' with anyone and everyone he fancies. Regardless, he still wants to use her for his own pleasures...

I’m used to making it worse made up of four letter words you want to know what it was now isolated and gone you fall apart at the seams I'll never know what it means try not to pull it apart You're aiming straight for the heart

Yeah, he has a violent nature, so don't test him with deep-cutting words--telling him exactly what he KNOWS he should be for her, or he might flip out.

you had to be the worst for me I don’t know what to say, so let me be and now I find you've left me behind I don’t know what to say, so nevermind!

Yeah, take the easy way out. Shut up, perhaps flip her the bird, and move on to the next 'piece of meat' What an a-hole!

Judging from the content of their "We Are Not Alone" album, I don't think this interpretation is very far off.
