Sunset and Twilight’s Song

So I’ve made reference to “their song” several times in my story. I’ve intentionally kept it vague partly because it kept changing in my own mind but also so you could insert whatever song you think fits best for them. I’ve grown curious as to what song y’all have inserted while reading. The songs that have popped up most in my head during those scenes have been “Miracle” by Foo Fighters, “Thunder” by Boys Like Girls and more recently “Let Me Be” by Escape the Fate. They all seemed to capture the relationship in one way or another.

So i pose the question to you. What song do you see as their song? there are no wrong answers, I’m just curious
