一首很悲伤的英文歌

unmistakable -------backstreet boys
歌词是：

Anytime, anywhere, any place.
You could be anyone today.
Maybe I recognize you on a crowded street.
Maybe you take me by surprise.
Will you be the one I had in mind?
There'll come a day.
When you walk out of my dreams.
Face to face
Like I'm imagining
Baby how can I be sure
That you're the one I'm waiting for
Will you be?
Unmistakable
People say watch your life through the glance
Desperately waiting on a chance
I know you're out there
Holding on holding out for me
Are we gonna know the time is right
What if you're here and I'm just blind
There'll come a day
When you walk out of my dreams
Face to face
Like I'm imagining
Baby how can I be sure
That you're the one I'm waiting for
Will you be?
Unmistakable
How can I own a soul
