The More I See You

This is a Jazz song by Michael Buble I just heard from Radio. It's good :)
the lyrics..

The more I see you,
The more I want you.
Somehow this feeling
Just grows and grows.
With every sigh I become more mad about you,
More lost without you,
And so it goes.
Can you imagine
How much I'll love you
The more I see you
As years go by?
I know the only one for me can only be you.
My arms won't free you;
My heart won't try.

How come all the jazz songs have the same kind of lyrics... :p
So straightforward and passionate hehe... then I start wondering if one day I will sing this song at the right time to the right person?
Do these songs usually serve this purpose? or they are usually used as a song to dance/ hum along?
Anyways it's still fun to sing along :D
