Day by day and night by night I feel you in my mind
It happens all the time you know my day dreams stop
My heart beats on I can't take it any more
It's you I live for

You are in my system, you are in my system
Don't you, don't you, don't you know that?

I will keep on pushing, pushing until I get through
My main objective, baby is to get to you
To turn your mind around I know will take time
But you know I can wait now, you're on my mind

Oh babe, you are in my system
I just want you to know that you, in my system
Got me burning, I'm on fire, oh, in my system
Everything I need you, in my system
Don't you, don't you, don't you know that, babe?

It's a romantic vision of me and you
It happens all the time, my dreams are filled with you
There's no doubt in my mind that I'll be true babe
You know I'll take you out and I'll keep loving you

You, you're in my system
Cut me right down to the wire you, in my system
Just want you to know that ooh, you are in my system, system
Got me burning, I'm on fire you, in my system

Can't make me believe you aren't
You, you're in my system, system
Got me burning, I'm on fire
Girl, you are in my system
Everything I need is you
