Or was this acceptable in the 60's?

Today I came across this song by Neil Sedaka called "Happy birthday Sweet 16". It appears that he released a song at age 22 singing about a girl he has known for a while and has been watching and waiting for her to come of age. I find it quite uncomfortable. You couldn't release such a song nowadays so was this okay in the 60's? AIBU to be so uncomfortable with a song that probably hasn't had airtime for 50 years?
Here are the Lyrics
Tra la-la-la-la, la-la-la-la
Happy birthday, sweet sixteen
Tra la-la-la-la, la-la-la-la
Happy birthday, sweet sixteen
Tonight's the night I've waited for
Because you're not a baby anymore
You've turned into the prettiest girl I've ever seen
Happy birthday, sweet sixteen
What happened to that funny face
My little tomboy now wears satins and lace
I can't believe my eyes you're just a teenage dream
When you were only six, I was your big brother
Then when you were ten, we didn't like each other
When you were thirteen, you were my funny valentine
But since you've grown up, your future is sewn up
From now on you're gonna be mine, so
If I should smile with sweet surprise
It's just that you've grown up before my very eyes
You've turned into the prettiest girl I've ever seen
Happy birthday, sweet sixteen

One I found much worse was somewhat more recent: the Barbie Girl song. This was targeted at, and being commonly publicly sung by, preteen girls. It asked the listener to undress them, touch anywhere etc. Whatever the intention, I fear it came off as a total paedo's delight.

Very true baby. Mil had to give half her wages to dm.

My dm was lucky as my dgm was very pro education so dm went away to college then lived in a flat share, early 60s.
