Hello /vp/

It's that time again!
Are you ready for my riddles? Because I won't go easy this time.Well....maybe I will,you are going up against ME of course.

So lets start, shall we?

But I get pass it
not that good of a singer but I make that one hit, a wonder.
Kids flinch when they feel me.
Men get burned from me.
I think its obvious by now, but who am I?
