Oh my gawd!!! I found another song just for my wedding, that is if I'm going to have one in the future. Haha! It's a lovely song, fell in love with it when I overheard it from the radio:
Lover's Concerto.

How gentle is the rain
That falls softly on the meadow
Birds high up in the trees
Serenade the clouds with their melody

Oh! See there beyond the hills
The bright colors of the rainbow
Some magic from above
Made this day for us
Just to fall in love

You hold me in your arms
And say once again you love me
And if your love is true
Everything will be just as wonderful

Now, I belong to you
From this day until forever
Just love me tenderly
And I'll give to you
Every part of me

Oh! Don't ever make me cry
Through long lonely nights without love
Be always true to me
Keep this day in your heart eternally

You hold me in your arms
And say once again you love me
And if your love is true
Everything will be just as wonderful
