Who Sang Someone? Showoff

A certain someone must be out there, waiting for a guy like me
A certain girl who will be my best friend, and think about me constantly
I'm searching for someone, who will always be with me
I'm searching for someone, girl I think of you constantly
Maybe it's you
I hope it's you
It's gotta be you
A certain someone must be saying I will meet my love someday
It's the same girl that I still dream of, and I don't even know her name
In my head I can see the shadows form before my eyes and
In my head I can see love taking up a new disguise and
In my head I can see myself alone without the truth and
In my head I can also see my happiness in you- yeah
Maybe it's you
I hope it's you
It's gotta be you
