Cover art for Underneath lyrics by Alanis Morissette

I think that this song is saying forget about the past because what's important is what's ahead: "So why spend all our time undressing our bandages When we've the ultimate key to the cause right here all underneath." Instead of thinking about the more painful memories, look at the things that matter now.

maybe?

regardless, this song is amazing.
