Lyric discussion by Replacementss 

The correct version of the lines are:

"All you ever wanted was someone Ma ain't scared of"

You can hear it more clearly in live versions of the song, for example at 2:25 in youtube.com/watch

@Replacementss It’s entirely possible that PW sang different variations of his lyrics live (which is not uncommon, at least that I’ve noticed), and the link you offered no longer works or I’d try to figure out what he sings at 2:25, as you recommended, but I am pretty sure (not 100%, but pretty close) that on the studio recording he sings exactly what is shown to be the lyrics, above (“someone Ma’d be scared of”). I hear just that.

An error occured.
