Who sings this song? (Increasing pitch, something with never to...)?

It's a woman who sings and the chorus is something like:

never to (run?)
never to (hide)
(na na na na)...

and the pitch is getting high

(nana na na na...)

and the pitch is getting low...

I don't know a complete phrase so I couldn't find it on google..
maybe someone who has already heard the "increasing and decreasing
pitch" might know..

thanks
