Name and artist of song

Some of the lyrics are:

Everything that you do,
I'm so in love with you
It keeps getting better
The rest of my life with
you by myself

Every little thing that you do,
Baby, I'm amazed by you

Thanks

The song is called "Amazed".

Most famously in recent years it was recorded by Lonestar, although I'm sure Bonnie Tyler did it before that. In 2006 Duncan James from Blue also covered it.

As you can imagine, Lonestar's one was the most rocky version of this country song, Bonnie's the most power balladish, and Duncan's the most Boy Bandesque, if any of those adjectives exist.

I don't know which version you heard, but it's certainly one of them.
