Well, obviously She's Mine is a love song.
And Jon already said this album "it's not a boy girl record, it's very topical", so that's a little disappointing to me.
And about Let It Rain, I'm not sure what's the Young Guns connection; is it the lyric or the melody, or both?
"somewhere there's a church bell/ that's summoning the choir/somewhere there's a dreamer who would walk 1,000 miles" is a throwback to the "Young Guns" era.
"I hadn't written anything like that in a long time. I like it because of the social justice of it, and taking a stand and saying let's purge ourselves of all of the hurt and hate and division, but who's going to be the one to stop it? Who's going to be the ones that unify us? So, let it rain and let's let the sun shine through."
