Hi, I am looking for a song. I know I've heard it in multiple movies,
it's just I cannot seem to find it's title, or for that matter, any
information other then as follows. These are the lyrics I know: "Do
you realize that you have the most beatiful smile, Do you realize?"
(repeated over, and over, and over.)
FYI, I don't think it's by Velvet Revolver. 

     Please help, it's been stuck in my head for too long!

Dear kara3478,

Though one word of the lyrics is different than the bit you remember,
I am absolutely sure that the song you have in mind is "Do You
Realize" by the band The Flaming Lips. The full lyrics of that song
are as follows:


Do You Realize - that you have the most beautiful face
Do You Realize - we're floating in space -
Do You Realize - that happiness makes you cry
Do You Realize - that everyone you know someday will die

And instead of saying all of your goodbyes - let them know
You realize that life goes fast
It's hard to make the good things last
You realize the sun doesn't go down
It's just an illusion caused by the world spinning round

Do You Realize - Oh - Oh - Oh
Do You Realize - that everyone you know
Someday will die -

And instead of saying all of your goodbyes - let them know
You realize that life goes fast
It's hard to make the good things last
You realize the sun doesn't go down
It's just an illusion caused by the world spinning round

Do You Realize - that you have the most beautiful face
Do You Realize

(Written by W. Coyne, S. Drozd, M. Ivins and D. Fridmann, The Flaming Lips)


"Do You Realized" was originally published on the Flaming Lips' 2002
album "Yoshimi Battles The Pink Robots". In 2003, the song was used
for the music soundtrack of the movie "How To Deal".
