Just Wanna Be with You
(high school musical)

I got a lot of things I have to do
All these destructions, our future's coming soon
We're being pulled in a hundred different directions.
But whatever happens I know I've got you

You're on my mind, you're in my heart
It doesn't matter where we are
We'll be alright, even if we're miles apart

All I wanna do is be with you, be with you
There's nothing we can do
I just wanna be with you, only you
No matter where life takes us
Nothing can break us apart
You know it's true, I just wanna be with you

You know how life can be, it changes over night
It's sunny then raining, but it's alright
A friend like you always makes it easy
I know that you get me every time

Through every up, through every down
You know I'll always be around
Through anything, you can count on me

All I wanna do is be with you, be with you
There's nothing we can do
I just wanna be with you, only you
No matter where life takes us
Nothing can break us apart
You know it's true, I just wanna be with you

"Through every up, through every down, you know I'll always be around. Through anything, you can count on me."
