Lyrics of Song

I am studying lyrics of song these days to catch the emotion inside words.
I found that I didn't understand the meaning of sentences.

For example, I read the lyrics of famous song which was titled " Can't take my eyes off you".
The first and second sentences of this song are below.

You're just too good to be true.
Can't take my eyes off you.

The meaning of these words are

I can't believe you are here or you are real existence,
because you are very very beautiful or wonderful more than any person who I met before.
So I can not stop watching you.

I thought the meaning of this song is "I was attracted by your beautiful eyes"
as for Japanese title of this song "君の瞳に恋してる”

I noticed the reason why I cannot sing a song well.
