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
