Cover art for Protection lyrics by Massive Attack

This incredibly beautiful song is about friendship between a boy and a girl, not a relationship. The relevant lines is "You've got a baby of your own, when your baby's GONE, she be the one, to catch you when you fall" It's not a standart love song, it's about "more than love". And there are not enough songs about friendship.

It could be about both.
