Day by day and night by night
I feel you in my mind
You know the day dreams stop
It happens all the time
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
I just want you to know that,

You are in my system
Don't you, Don't you, don't you know that, babe.
You oooohhhh you're in my system, system

Until I get through
I will keep on pushing, pushing, pushing
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
You are in my system
I just want you to know that,
You are in my system
Got me burning, I'm on fire
You, you're in my system
You're everything I need
You, oooohhhh, you're in my system, system
Don't you, Don't you, don't you know that, babe.

It happens all the time
It's a romantic vision of me and you
My dreams are filled with you
There's no doubt in my mind
That I'll be true baby
You know I'll take you out
And I'll keep lovin' you

Oh baby you are in my system,
You are in my system
I just want you to know that
Cut me right down to the wire
You, ooohh, you're in my system
Got me burning I'm on fire
You, you're in my system
Can't make believe
You, you're in my system
You're everything I need
You, Ooohh, you're in my system
I just want you to know that
You, you're my system
You, you're in my systemGot me burning I'm on fire
